Good price, it worked well the hold trip and it arrived on time to the Hotel.
Recomended!

I didn't have issues, sim worked perfectly

Good coverage during the complete roundtrip

Worked perfectly for me.

everything went well, excellent service

connection is stable, in various different prefectures. setup is relatively easy as well. would recommend.

The SIM card really came in handy. With full-speed first 3GB and the rest in slower speed, I managed to deplete it only once.

I USED THE SIM MY WHOLE HOLIDAYS AND IT WAS GREAT ALL AROUND THE COUNTRY, BECAUSE WE VISITED A LOT OF CITIES.

The price is good for what they offer, especially if compared to some competitors that seem keen on ripping tourists off. The SIM arrived earlier than the specified time, luckily someone was there to receive it for me. It included instructions and the metallic pin for opening the phone SIM slot. It started to work shortly after setup, speed was decent and I never ran into limitations for intensive use. The SIM is white and unbranded, and the operator turned out to be IIJ, a MVNO which utilizes the NTT DoCoMo network. Reception was not as good: in several places I would lose Internet connection even though the indicator on the phone seemed healthy. I blame this on the MVNO being given second-rate service from Docomo, or on Docomo simply being worse than SoftBank. My friend on SoftBank alway had usable Internet when mine was cut off.

Not a single problem. Easy to get at the Airport
