Works great!
This was my second time renting the Platinum - it worked just as great as the first! We only had one connection problem, and that was easily fixed by a quick reboot. There were two people using it this time, and there was enough data for both of us to be using Google Maps, Yelp, keep family/friends updated by posting a few photos each night, etc. By the end of our 1-week trip, we had only used 8 or 9 gbs, so the 10gb/3days is plenty for most people!

Great experience!
I was scrambling around last minute trying to find portable WiFi before my trip when I found Japan WiFi Buddy. Super affordable for the week I was spending during my trip! I got the diamond package, which gave me so much space (even with my friends hooked up to the hotspot!) It was super easy to use and did not take up any room in my bag, and I even carried it in my jacket pocket sometimes while exploring my hostel's neighborhood. I'd definitely use this again during my next trip to Japan!

Great Service!!!
We reserved the Diamond package for 12 days, and all I can say is that it was perfect for us: we had service everywhere (Osaka, Kyoto & Tokyo, and in between these cities during the trip on the Shinkansen) with no interruptions at all. We even used it at the hotel's rooms, since the connections and the speeds were better than the ones offered by the hotels. Just keep it fully charged (we charged it every night), and take the battery pack with you (including the necessary cable); if you are a heavy user as we were, you might need it late in the afternoon. I would not hesitate to recommend it to everyone!!!... 5 STARS!!!
