The first time I visited Japan was in 2018 when I went together with a friend of mine – Ditmar.
It was a hectic summer, as I also visited China a few weeks before and the Netherlands three times (before, between & after those trips – I was living in Denmark back then).
What surprised me is that the Japanese government banned the sale of voice-enabled SIM cards to travelers in 2006 for some reason.
As a result, only data-only SIM cards are sold to visitors like you and me.
Because VoIP (Voice over IP) apps like WhatsApp were already popular back then, it did not bother us that we could not make phone calls.
Since then, a lot has changed – travel eSIMs exist, and they are incredibly popular.
And I love trying them out to see which performs the best in individual countries like Japan.
So I revisited in 2023 and stayed in the Kansai Region (mostly Osaka) and Tokyo (again).
This resulted in me spending more than 480 USD for my Japan SIM card and travel eSIM review series (50 030 JPY (≈ 360 USD) on Japanese SIM cards and 121.50 USD on travel eSIMs to be used in Japan) – yeah… I went all out for you 😎.
I am excluding the cost of Airalo's Asialink 100 GB eSIM (185 USD) and its Discover Global 20 GB eSIM (89 USD) because I use both in multiple countries, not just Japan.
In many countries, getting a local SIM card will be the most cost-effective way to stay connected.
But that is not the case in Japan – they are criminally expensive.
Worse, almost all the Japanese SIM cards I tested had speed caps of 2 Mbps, 10 Mbps, or “unrestricted” speed for the first few days (often up to three days) before speeds would drop.
And I am talking about SIM cards that supposedly have no Fair Use Policy (FUP), and promise speeds up to 788 Mbps, or whose FUP I had not hit.
As a result, there is only one Japanese SIM card I recommend – but that one is expensive too.
Travel eSIM providers like Airalo are way cheaper than Japanese SIM cards.
Surprisingly, they performed significantly better – even when roaming on the local networks.
This phenomenon is uncommon but happens in countries where mobile operators throttle (prepaid) speeds.
Because the Airalo Moshi Moshi eSIM is basically cheaper than any Japanese SIM card available while having a significantly better performance than them, I can already recommend it if your phone supports eSIM.
Throughout this review, you will discover why I think this way, so let's start immediately!

Which Phones are Compatible with Airalo eSIMs?
Before discussing the Airalo Moshi Moshi eSIM to be used in Japan specifically, you must know whether your phone can even support Airalo's eSIMs.
Sure, your phone may support eSIM, but the local mobile operator and travel eSIM provider, like Airalo, first needs to certify a phone before the users can use their products.
As of August 2023, the phones shown in the infographic below are compatible with Airalo eSIMs:

With that out of the way, let's talk more about the Airalo Moshi Moshi eSIM!
How Much Does the Airalo Moshi Moshi eSIM Cost (for Japan)?
You can get the Airalo Moshi Moshi eSIM to be used in Japan for as little as 4.50 USD for 1 GB (7 days) and up to 26 USD for 20 GB (30 days).
Below is an overview of how much each Airalo Moshi Moshi eSIM costs:
- Japan/Moshi Moshi 1 GB eSIM for 7 days, costing 4.50 USD
- Japan/Moshi Moshi 2 GB eSIM for 15 days (new), costing 6.50 USD
- Japan/Moshi Moshi 3 GB eSIM for 30 days, costing 8.50 USD
- Japan/Moshi Moshi 5 GB eSIM for 30 days, costing 11.50 USD – very popular with Phone Travel Wiz readers
- Japan/Moshi Moshi 10 GB eSIM for 30 days, costing
189 USD (on sale) – very popular with Phone Travel Wiz readers - Japan/Moshi Moshi 20 GB eSIM for 30 days (new), costing 26 USD – most popular with Phone Travel Wiz readers (this is the one I used during this trip)
Note: Phone Travel Wiz reader popularity ranking was updated in December based on data up to the 30th of December (2023 data only). The (promotional) prices were updated on the 31st of January.

Regardless of the currency used in your country, Airalo will always charge you in USD (US Dollar).
If your credit/debit card charges you foreign exchange fees, get yourself a Wise Borderless Account and Debit Card.
Their fees are MUCH lower than banks and credit card companies charge you (and Wise is transparent about their fees, unlike banks).
I have saved literal THOUSANDS of Australian Dollars and Euros, my main currencies, when using Wise abroad when traveling compared to my debit and credit cards.
Moreover, regardless of which Airalo Moshi Moshi eSIM you choose, you can always top it up for the same amount of data and prices as listed above.
For example, suppose you buy the 5 GB Airalo Moshi Moshi eSIM (30 days, costing 11.50 USD) but realize you need more data.
You can top it up with the 3 GB top-up (30 days, costing 8.50 USD) or the 20 GB top-up (30 days, costing 26 USD).
Many eSIM providers out there do not allow you to top up or extend the validity of your eSIM, so it is cool that Airalo allows you to do so.

My Airalo Moshi Moshi eSIM in Japan Experience
I used my Airalo Moshi Moshi eSIM in Hiroshima, the Kansai region (mostly Osaka, but also Kobe, Kyoto & Nara) & Tokyo Metropolis (mostly Chiyoba City, but also Shinjuku City, Taito City & Yokohama City).
Before we continue, I do want to let you know how travel eSIM providers like Airalo work.
It is impossible for Airalo, or any other mobile operator, to operate in every country (and do not trust any company saying otherwise), so they set up roaming agreements.
And do not get worried by the word roaming yet – roaming can be expensive, but roaming with Airalo or many other travel eSIM providers, will not result in a 5000 USD roaming bill.
What Airalo does, and basically all (actual) mobile operators do, is partner up with a local mobile operator so that their customers can still stay connected when abroad.
In the case of Japan, the Airalo Moshi Moshi eSIM uses the SoftBank and AU by KDDI networks with the help of Singtel from Singapore (so your phone, apps & site may claim you are using a Singtel eSIM instead of an Airalo one – that is correct).
Note: Airalo does not always use multiple networks.
In my case, I was mainly on the SoftBank network, although I did not actively track which network I was on all the time.
While you can manually select a network, it is unnecessary.
And as you will find out later, the performance of SoftBank and AU by KDDI are similar, so it does not matter which one you choose.
The Japanese mobile operators are not in the prepaid business for whatever reason, so I mostly used Mobile Virtual Network Operators (MVNOs) using the NTT Docomo network through another MVNO called IIJmio.
All Japanese SIM cards I used using IIJmio were mostly/always throttled @ 2 Mbps, 10 Mbps, or would start off normally for the first (few) day(s) before being slowed as well.
I go more in-depth about that in my individual Japanese SIM card reviews, but all the travel eSIMs I used, including Airalo's Moshi Moshi eSIM, were not affected by this nonsense… so that was amazing 🤣.
So while I usually compare my eSIM results with the local mobile operator, it is not something I can do in Japan consistently because all the SIM cards I tried were MVNOs 🥲.
But worry not – I will do my best, mostly because I tried nine travel eSIMs using the networks of the Big Three (NTT Docomo, Softbank & AU by KDDI) with varying results.
When looking at 4G/LTE availability in Japan, the three mobile operators cover practically all of the country, with an availability of at least 99.4%.
Rakuten Mobile exists in Japan too, but tourists cannot get its prepaid SIM cards. Moreover, none of the SIM cards or eSIMs I used were using its network, so I will ignore its results in this analysis.
Japan's 4G/LTE reception is so good that you will unlikely be stuck on 3G at any time.
Unless you did not turn off airplane mode while taking off to send a quick message… I know who you are 😏.
In terms of 5G NR, the Airalo Moshi Moshi eSIM did not support it when I was in Japan, so I will not go over that for now (but I will go back when it does support 5G NR, like the Ubigi eSIM on the NTT Docomo).
In terms of speed, NTT Docomo has the fastest download speed, with a median download speed of 48.86 Mbps, ahead of SoftBank (44.77 Mbps) and AU by KDDI (41.60 Mbps).
But these results are somewhat similar, so you can say they have roughly the same speed.
The same can be said about upload speeds, where SoftBank is leading the pack (9.24 Mbps), followed by NTT Docomo (6.97 Mbps) and AU by KDDI (6.40 Mbps).
I did speed tests with the Speedtest app in three regions throughout Japan.
For reference, I consider an average download speed of 25 Mbps and an average of 10 Mbps upload speed fast enough.
Preferably, download speeds should be 100 Mbps+ on 4G/LTE… but we are not there yet 🗿.
But why these averages?
A download speed of more than 25 Mbps is enough to video stream content @ 4k resolution.
Social media sites that allow for live streaming, like Facebook Live, recommend an upload speed of at least 10 Mbps.
So, that is why – but that does not mean that a download speed of less than 100 Mbps excited me 😏.
But Australia spoiled… everything slower than 300 Mbps is slow now 🤣.
Anyway, you will also see that some of the results are in two shades of red, green, underlined, or in italics.
Underlined results are on 5G NR, while results in italics are on 3G.
The green shows that the result was the fastest on the network at said location.
For example, the Airalo Moshi Moshi being the fastest travel eSIM on the SoftBank network in a mall.
While red shows that the result was the slowest on the network among its peers at the location.
Okay, that is enough background information – let's compare the Airalo Moshi Moshi eSIM to other travel eSIMs primairly using the SoftBank network in Hiroshima, the Kansai region & Tokyo Metropolis.
Airalo Moshi Moshi eSIM Speed Test Results in Hiroshima
Hiroshima is mainly known for an incident that happened in 1945.
However, the radiation levels are so low nowadays that they are comparable to other Japanese cities – or most other cites worldwide.
Besides its history, it has much to offer, such as the Hiroshima Castle.
Including this cute variation of the castle.
Hiroshima on its own is worth visiting, although it can be a nice day trip or weekend getaway if you are in the Kansai region (Osaka) already.
While Hiroshima may or may not be among the ten largest cities in Japan (it used to be until the 2010 census – that is when it fell out of it), 5G NR was somehow not available in the city.
COMST Japan, an NTT Docomo Mobile Virtual Network Operator (MVNO), and Ubigi Japan, using the NTT Docomo network, both have 5G NR access.
However, that technology was nowhere to be found throughout Hiroshima.
As a result, it was a leveling playing field to compare all the Japanese SIM cards and travel eSIMs I used because they all were on 4G/LTE.
For now, let's see how the Airalo Moshi Moshi eSIM performed in Hiroshima:
Fast speeds with the Airalo Moshi Moshi eSIM in Hiroshima.
I did not get as many results as I would like to (seven) because Hiroshima was a day trip and was not part of the Kansai region as I initially expected it to be.
Even then, I got you some results in seven test locations 😎.
Anyway, the Airalo Asialink and Nomad APAC eSIMs also used the SoftBank network, so the screenshot above shows their results too.
The Nomad Japan eSIM used the NTT Docomo network because I used the Truphone variant instead of the JoyTelecom one (like the APAC version). That is why I omitted the Nomad Japan eSIM from the list above.
You can see that the Airalo eSIMs, Moshi Moshi and Asialink, performed similarly well.
For some reason, Nomad's APAC eSIM was close to twice as slow as the Airalo eSIMs .
As you may recall, the Airalo Moshi Moshi eSIM is powered by Singtel from Singapore – this applies to the Asialink eSIM too.
Whereas the Nomad APAC eSIM is powered by JoyTelecom from Hong Kong, meaning the routing is different between the two.
Back to the Airalo Moshi Moshi results, there is not that much to say.
I had an average download speed of 67.46 Mbps and a median download speed of 55.25 Mbps with the Airalo Moshi Moshi eSIM: it passed the 4K video streaming test in Hiroshima (minimum of 25 Mbps).
The same can also be said for the HD live streaming test in Hiroshima – the Airalo Moshi Moshi eSIM had an average upload speed of 18.35 and a median upload speed of 18.12 Mbps, making it pass the HD live streaming test (minimum of 10 Mbps).
Sometimes, the Moshi Moshi eSIM was faster than the Asialink eSIM. Sometimes, it was not.
As they are practically the same eSIMs, although the Moshi Moshi eSIM is geofenced for Japan only, the results should be similar.
But we can see that the Moshi Moshi eSIM had a download speed of 200.33 Mbps at Hiroshima station.
In comparison, the Asialink eSIM had a speed of only 24.19 Mbps.
Or when the Asialink eSIM had a download speed of 109.37 Mbps, whereas the Moshi Moshi eSIM had a speed of only 51.61 Mbps.
It could be that the tower/antenna was busier when I did the tests after each other.
Either way, as we saw with the average and median speeds between the two eSIMs, they will perform incredibly well in Hiroshima.
In fact, the Airalo Moshi Moshi and Asialink eSIMs were the best-performing travel eSIMs in Hiroshima in terms of speed.
While COMST Japan, an MVNO directly using the NTT Docomo network (the only one not going through IIJmio), was slightly faster in terms of download speeds (average of 70.48 Mbps) but significantly slower when looking at upload speed (average of 9.15 Mbps).

Airalo Moshi Moshi eSIM Speed Test Results in the Kansai region (Kobe, Kyoto, Nara & Osaka)
While the term Kansai region may not ring a bell for some readers, it is the second-largest region in Japan (behind the Kanto region, which includes Tokyo Metropolis).
The Kansai region is home to the famous Osaka but also Japan's former capital Kyoto.
And a few others like Kobe (yes – the one from Kobe Beef) and Nara (with the large deer park).
Most tend to stay in Osaka when they are in the Kansai region.
But I would highly recommend visiting one of the cities I mentioned earlier because (1) you are nearby and (2) they are worth the visit!
Osaka and the Kansai region was my first destination during this Japan trip.
Here, I learned that most Japanese SIM cards are slow.
And I could not contribute that to me being in some remote town… because Osaka is Japan's third-largest municipality (behind Tokyo and Yokohama (south of Tokyo)) and it has 5G NR (which I used with COMST Japan and Ubigi Japan).
As the Airalo Moshi Moshi eSIM is not powered by a Japanese mobile operator, I had a pleasant performance with it in the Kansai region.
In fact, it was the best travel eSIM I used in the region.
So, let's see how the Airalo Moshi Moshi eSIM performed in the Kansai region:
Fast speeds with the Airalo Moshi Moshi eSIM in the Kansai region.
Because the Airalo Asialink, Airalo Discover Global, Nomad Japan & Nomad APAC eSIMs also used the SoftBank network, I showed their results in the screenshot above as well.
Unlike in Hiroshima, where the Airalo eSIMs (excluding the Discover Global eSIM because I did not test it there) where the clear winners, the Nomad eSIMs performed impressively well in the Kansai region.
It could be because I had way more results here (53 vs. 7) 🤭.
Back to the Airalo Moshi Moshi results, I had an average download speed of 49.91 Mbps and a median download speed of 36.35 Mbps with the Airalo Moshi Moshi eSIM: it passed the 4K video streaming test in the Kansai region (minimum of 25 Mbps).
The same cannot be said for the HD live streaming test in the Kansai region – the Airalo Moshi Moshi eSIM had an average upload speed of 9.70 Mbps and a median upload speed of 6.34 Mbps, making it fail the HD live streaming test (minimum of 10 Mbps).
The fastest download speed with any travel eSIM on the SoftBank network in the Kansai region was with the Airalo Moshi Moshi eSIM.
That was in the Kimono Rental Gion Nishiki – Gion Store in Kyoto – a download speed of 375.39 Mbps.
This result was also faster than any other SIM card and travel eSIM I tested in this store.
By the way, I rented a kimono for roughly 3500 JPY at this store, which is lower than most stores in Kyoto. The colors are not as exciting as other stores, but they do what they need to do. For a Kyoto photoshoot in your Kinomo, I recommend Soma from Travel Japan Together through Airbnb (not sponsored or anything – I just loved the experience!
Other locations where the Airalo Moshi Moshi eSIM managed to get a download speed of more than 100 Mbps were at Naniwabashi Station (103.32 Mbps) and Yodoyabashi Station (127.50 Mbps) – both in Osaka.
Of all the cities I tested the eSIM in (Kobe, Kyoto, Nara & Osaka), the one with the highest average download speed was in Kyoto (86 Mbps) – mostly because of that 375.39 Mbps result I mentioned earlier.
Below is an overview of the average download speed I got in each city:
- Kobe: 30 Mbps
- Kyoto: 86 Mbps
- Osaka: 44 Mbps
- Nara: 44 Mbps
What about upload speeds with the Airalo Moshi Moshi eSIM in the Kansai region?
Surprisingly, average upload speeds are pretty slow in Japan by East Asian standards.
The average upload speed with the Airalo Moshi Moshi eSIM in the Kansai region was only 9.70 Mbps.
Other travel eSIMs, or even the Japanese Mobile Virtual Network Operators (MVNOs), did not do much better, so it is not an Airalo issue.
Even then, the eSIM got the fastest upload speeds in the Harbor Center and San Center Plaza in Kobe (30.07 Mbps and 29.11, respectively).
In Osaka, the locations were Matsunoya Imafuku Tsurumi Restaurant and Naniwabashi Station (38.02 Mbps and 22.74 Mbps, respectively).
But besides these outliers, there is not much to say because the majority of results were below 10 Mbps, while some were between 10 Mbps and 30 Mbps.
Nonetheless, the Airalo Moshi Moshi eSIM is the best-performing travel eSIMs in the Kansai region in terms of download speed.
With the average upload speed ranging from 8 Mbps to 14 Mbps between all the travel eSIMs and Japanese SIM cards I tested in the Kansai region, the Airalo Moshi Moshi eSIM did alright with an average speed of 9.70 Mbps.

Airalo Moshi Moshi eSIM Speed Test Results in Tokyo Metropolis (Chiyoba, Shinjuku, Taito & Tokohama)
Tokyo, or the Tokyo Metropolis, probably does not need an introduction.
As you probably already imagining a bustling city with bright lights.
Which… it certainly is!
But do know that Tokyo consists of 26 cities (+a few towns and villages).
In fact, Tokyo Metropolis has 39 municipalities under its name.
This is why the heading for this section had Chiyoba, Shinjuku, Taito & Tokohama in parentheses because those are the cities I visited on this trip.
But wherever you go in Tokyo, you will have guaranteed fun 😄.
Let's see how the Airalo Moshi Moshi eSIM performed in Tokyo Metropolis:
Fast speeds with the Airalo Moshi Moshi eSIM in Tokyo Metropolis!
Because the Airalo Asialink and Nomad APAC eSIMs also used the SoftBank network, I also showed their results in the screenshot above.
I had an average download speed of 54.09 Mbps and a median download speed of 37 Mbps with the Airalo Moshi Moshi eSIM: it passed the 4K video streaming test in Tokyo Metropolis (minimum of 25 Mbps).
The same cannot be said for the HD live streaming test in Tokyo Metropolis – the Airalo Moshi Moshi eSIM had an average upload speed of 8.86 and a median upload speed of 6.58 Mbps, making it fail the HD live streaming test (minimum of 10 Mbps).
The fastest download speed with any Japanese SIM card or travel eSIM was four times with the Airalo Moshi Moshi eSIM.
In Chiyoba City, it was at Kanda station and the Mansei Bridge (close to Akihabara), with 213.97 Mbps and 37 Mbps, respectively.
The other two locations were at the Schmatz Beer Stand Wing Takanawa Bar in Minato City (215.82 Mbps) and the McDonald's in Takadanobaba District in Shinjuku City (128.52 Mbps).
Even when excluding these results, I managed to get download speeds faster than 100 Mbps at only one more location: Gransta Mall in Chiyoba City – 106.14 Mbps.
While the Airalo Moshi Moshi eSIM had the slowest download speed at six of the 31 locations, they were within a reasonable range compared to the Airalo Asialink and Nomad APAC eSIMs.
This could also be said about upload speeds.
Often, they were within an acceptable margin compared to the Airalo Asialink and Nomad APAC eSIMs.
Although I do not know what happened at the Kamonka Ueno Bamboo Garden Restaurant in Taito City, where the Airalo Moshi Moshi eSIM had an upload speed of 2.10 Mbps.
While the Airalo Asialink and Nomad APAC eSIMs had upload speeds of 15.92 Mbps and 13.02 Mbps, respectively.
Or Akihabara Station in Chiyoba City – 1.98 Mbps.
Compared to 10.04 Mbps and 8.90 Mbps in the same order again.
It could be that the tower/antenna was busier when I did the tests after each other.
As the average upload speed between the three eSIMs is between 8.68 Mbps and 10.88 Mbps, I cannot say the Airalo Moshi Moshi eSIM is inherently slower than the others because they are too similar.

My Overall Experience with the Airalo Moshi Moshi eSIM in Japan – Is It Any Good?
I would recommend the Airalo Moshi Moshi eSIM, and it would be one of my top recommendations for anyone wanting to buy a Japanese travel eSIM.
Getting the Airalo Moshi Moshi eSIM, and any other Airalo eSIM for that matter, is easy and straightforward (even though I did not spend any time on how to install Airalo eSIMs – you will manage… promise!).
Airalo's Moshi Moshi eSIM is also one of the most affordable eSIMs I tested on my trip while having various options (1 GB, 2 GB, 3 GB, 5 GB, 10 GB & 20 GB).
In Japan, it uses the SoftBank and AU by KDDI networks, which have practically excellent 4G/LTE availability (just like NTT Docomo – the other mobile operator part of the Big Three).
But, I was primarily on the SoftBank network with the Airalo Moshi Moshi eSIM.
However, you can manually select the AU by KDDI network if you want to (which would be unnecessary… but you have the choice!).
The other two Airalo eSIMs that cover Japan (Asialink for Japan and 13 other Asian East- and Southeast countries and Discover Global for Japan and 84+ other countries globally) also use the SoftBank network.
You will have the fastest network experience with the Airalo Moshi Moshi eSIM (compared to other travel eSIMs I have used in Japan).
There was only one Japanese SIM card, COMST Japan, that was faster (because it had 5G NR access in the Kansai Region and Tokyo Metropolis).
So… the eSIM is an excellent choice 😳.
Taking all 91 speed tests into account, I had an average overall download speed of 52.72 Mbps and a median download speed of 38.34 Mbps with the Airalo Moshi Moshi eSIM.
When looking at upload speeds, I had an average upload speed of 10.02 Mbps and a median upload speed of 6.96 Mbps with the Airalo Moshi Moshi eSIM.
The upload speeds are not impressive because the Japanese mobile operators already have slow speeds.
So the Airalo Moshi Moshi eSIM could not do better in that regard.
Normally, I would tell you how much faster or slower the Airalo eSIM would be compared to the network it uses (SoftBank, in this case).
But because Japanese mobile operators do not care about travelers who want prepaid SIM cards, I could not get a SoftBank SIM card.
Instead, only Mobile Virtual Network Operators (MVNOs) sell prepaid SIM cards, and they go through another MVNO, which aggressively throttles speeds.
So… no Airalo Moshi Moshi vs. SoftBank comparison 😔.
But as I said, no other travel eSIM was faster than the Airalo Moshi Moshi, and only one Japanese SIM card was faster (COMST Japan).
The Japan Wireless eSIM, using the AU by KDDI network through China Mobile Hong Kong, came close with an average download speed of 47.35 Mbps.
But unlike the Airalo Moshi Moshi eSIM, I used it in Tokyo Metropolis only (whereas I used the former in Hiroshima and the Kansai region too).
So I suspect its average would be dragged down a bit if I used it outside the capital area too.
Airalo's Asialink eSIM, which I recommend if you visit two or more countries in East- and Southeast Asia for the best prices, did well too.
The Airalo Discover Global eSIM, however, was almost always the slowest travel eSIM I tested 😒.
With an average download speed of 10.05 Mbps in the Kansai region, it was no match for its “competitors”.
So I did not bother using and testing it in Hiroshima and Tokyo Metropolis because… I knew enough 🤣.
While I do not recommend the Airalo Discover Global eSIM when you visit one country only, like Japan, it is a useful eSIM for those traveling multiple continents or countries not supported by regional Airalo eSIMs (like its Asialink eSIM – select East- and Southeast Asian countries only).
By using a near-perfect 4G/LTE network, offering affordable data plans (cheaper than Japanese SIM cards) & offering super-fast download speeds, you should have a smooth browsing experience with the Airalo Moshi Moshi eSIM.
