There are more and more places offering free WiFi in Japan, and even the Japan Tourism Agency is promoting WiFi settings that are very convenient for foreigners. However, if foreign tourists use smart phones to surf the Internet in Japan, they may violate the Radio Law.
According to the Japanese news-postseven website reported on June 5438+05, Japan has strict regulations on terminal equipment accessing wireless networks. If the wireless network is used through terminals such as mobile phones and tablet computers that are not marked with the' technical standard applicability logo', it will be regarded as a violation of the Radio Law in principle. But under the same circumstances, if international roaming is used, telephone operators will issue licenses and certificates for wireless Internet access.
However, this provision is inconsistent with the actual situation in many places. In Kyoto, which is deeply loved by foreigners, a service that anyone can use WiFi (Kyoto _ WiFi) for 3 hours for free was started last summer. MICE Zhenxing Office of the Kyoto Bureau of Industry and Tourism said that the service did not explicitly indicate that terminals without the "technical application logo" could not be used.
At the same time, all parts of Japan are promoting more free WiFi for the convenience of foreign tourists, but only a few cities such as Yamanashi Prefecture indicate in Japanese and English that "only terminal devices that have passed Japanese technical standards can use WiFi". Gao Qiao Yide of the Tourism Promotion Division of the Ministry of Tourism of Yamanashi Prefecture said, "This regulation is not mandatory, just to attract attention."
