The school venues and the lodging facilities in Tokyo and Tsuruga have good access to the Internet. It will be convenient for you to have a computer so that you can use it during your off time, too.
For Overseas Participants, you should also bring a plug adapter because the type of plugs can be different from those of your country. Please see the information about plugs in “About Japan” in General Information and Maps. Also you can buy one in Tokyo on the day you will arrive or after the every-day classes on weekdays but you have to manage to take subways and to find an electric shop.
