Very convenient, good speeds
Nothing like streaming the season premiere of the Witcher in 4k on a bullet train sipping whisky.

Great service and great device
The Platinum WifiBuddy was perfect for our two week trip to Japan. The employees were also super friendly and communicated everything we needed to know about pick-up prior to our trip. We were a group of two people using the device mostly for web searches and mapping directions (rarely streaming audio or video). For the most part we had a fast connection throughout our entire trip and managed to get by without even needing a sim card. We had some minor issues with slow connections in rural/underground or very crowded areas but it was never for an extended period of time. If we visit Japan again we would rent this same device from JapanWifiBuddy again in a heartbeat!

Easy pickup, setup, operation, and drop off.
I picked up the package from the post office at Narita Airport, turned it on, logged in using the sticker on the back of the device, and was on the internet. We kept it on and used it everyday and all day (running 4 phones) and the battery still had around 20% left by 10pm at night. Charge it up overnight and it's ready to go again the next day. An external battery was included but we never needed it. Service was great the whole time in Tokyo, Osaka, Kyoto, and Hiroshima. At the end of the trip we put everything into the included preaddressed envelope and dropped it in the post box at the Haneda Airport International Departures Lobby. It couldn't have been easier or better. We'll use WifiBuddy next time we visit Japan. Thanks!
