Now carrying a tablet PC such as an iPad and/or a smart phone has become a normal style of travelling abroad. But, 3G Internet connection abroad is expensive and there are few free Wi-Fi spots in Japan. Most Wi-Fi services need registration or mail certification through a screen in Japanese and/or fee.
Perfectly free Wi-Fi service without any registration nor fee is now available at Kurasshic-kan, a landmark of a popular stroll Nakamachi Street in Matsumoto. You can connect with Wi-Fi in a open public space, a cozy tea room, and a square in front of it, from 8:00 till 22:00 there.
Another free Wi-Fi spot in Matsumoto is a cheep cafe restaurant with a good view on the 10th floor of Toko City Hotel in front of the Matsumoto Station.In and near the Tourist Information Center in front of the Hotaka Station which is a gateway to the Daio Wasabi Farm also offers perfectly free Wi-Fi service. Another perfectly free Wi-Fi spot I know is Hoshino Resort Area in western Karuizawa including ”Harunire Terrace” a fancy wooden deck street you can enjoy shopping, cuisine and stroll.
