"Absolutely priceless…"

Absolutely priceless for our two weeks travelling around Japan.
We collected from Ninja WiFi in Tokyo airport. A little difficult to find, so allow yourself time, but really efficient once we found them.
We had two devices (and found a 25 % discount code online) for our family of 4. They worked perfectly the whole time and made our lives so much easier.
By having two. we're able to split off and still be able to stay in touch.
The charge easily lasted a day and then we charged them overnight.
The return was easy too, but the return post box is BEFORE security, so find it immediately before or after you check your bags in.
Would absolutely use them again

"Easy pick up at Handea AirPort"

Easy pick up at Handea AirPort
I used a 4G modem - with an extra powerbank thats was included.
Good coverage with good speed.
Charge the modem first for best experience then use as a backup the Powerbank.

"What can I say...I purchased a SIM car…"

What can I say...I purchased a SIM car for tourist, the 30days version and 10GB. All the instructions were in Japanese only !! So, don't call this a data sim card for tourist ! I had to go in a starbuck cafe to use google lens and translate all the process step by step.
Result 2 hr wasted...
After the network is good and it works, so for this part, no problem.
Please understand people. We are just landing, you purchased a tourist data sim card and the instructions to set the APN are only in Japanese...But it is aimed for tourists ?!? Anyway, sometime logic is not the same everywhere.

"Pocket wifi"

I've ordered a pocket wifi. Everything ws there, but:

- cable didn't work, so I had to use my own cable
- power off after +/- 5 hours. Ok there is powerbank... which charges only for 2hours.

So: in case of emergency, you have wifi. But certainly not for the whole day!

"Terrible company and dishonest "

Esim didn't work even though I've never had a problem with other esims. Emailed Japan Wireless as that's the only way to contact them. No reply so after a few hours of having a phone not working I eventually had to buy from another company. When they did finally reply the customer service was useless and also said they cannot process a refund despite having sold me a product that didn't work. I'd avoid these guys and go with one of the other big providers. Oh and they sent me an email afterwards asking me to review. Gave them one star and surprise, surprise they haven't published it! Dishonest company in the extreme.

"Esim was a joke"

Esim was a joke. I paid and when I am here it's totally useless. I am using Samsung S24 so the phone is not the issue. I got scammed. Email them, messaged them no reply. Pls stay away

"Great pocket wifi provider for Japan"

Really surprised at the low reviews on here.

Just returned from 14 days in Japan and chose Japan wireless as our pocket wifi provider. We chose premium package, unlimited data and the signal was great the whole time.

Battery life was really good, sometimes we did have to use the spare battery pack but only once or twice and we used the wifi A LOT during our stay, it really is necessary to have a good signal for navigation purposes and help guiding for trains etc.

Never used the translator as we used Google translate on our phone.

Great experience, no issues at all.

Easy collection and return at Haneda Airport.

"Très satisfait de ce service peu onéreux."

J'ai acheté une carte SIM pour essentiellement pour pouvoir bénéficier des données mobiles et utiliser google maps. La carte était disponible à mon hôtel à mon arrivée à Tokyo et a parfaitement fonctionné pendant les deux semaines de mon séjour.
Je suis très satisfait de ce service peu onéreux et je le recommande.

"Please get rid of older router models which do not work properly"

I have been using their pocket wifi for more than a year now as my husband and I travel to Japan frequently. I have experienced several issues with them. Although they always offer a replacement, they do not seem to understand a replacement might not help at times. I think the best they can do is

1. inspect all their charging cables and router before shipping out.

2. make sure their router are up-to-date. Old ones should be got rid of ASAP.

I missed an important meeting because of the router they sent me was old and did not work properly. At first I thought it might be due to long holidays and that many people are sharing the narrow bandwidths they rent from NTT Docomo. This was the case in January 2023 but yes I can understand.

But later when I received the replacement I found out that was not the case.

Replacement router is a newer model which works perfectly.

"Be very careful with Japan Wireless"

Be very careful with Japan Wireless, also known as Global WiFi and Ninja WiFi. Be aware that these companies are associated with JRail Pass and if you opt for a mobile WiFi remote you will deal with them, not directly with JRail Pass. Up front, they seem like a good, reliable, customer-friendly company but their policies for anything out of the ordinary are not consumer-friendly at all. I accidentally left a remote battery charging cord/cable in the black case when I returned the WiFi unit. When I contacted them for the return of the unit (i.e., to mail the small 8 cm cord back to me) the charge was ¥20,000/$133.33. After a round of protest emails and their "Valued Customer" policy replies the price was lowered to ¥5,000/$33.33. My battery-charging unit costs less than that. In the end, I declined their "offer" and bought a new charging unit for less. The "logistics" team is not at all customer-friendly. Moral of the story - double check the black case before you return the WiFi unit and expect to be exploited for anything out of the ordinary.
