I plan to watch it and be in the chat too! It is all in Japanese so you don't have to join in the chat if you don't want to, but do watch the broadcast at least! If you do join the chat please keep in mind that Toshi and anyone else inside and outside of the booth can read the chat window. In other words, please do not be rude or say anything that would embarrass you or your country of origin. For example, please DO NOT ask for English/other language translations as he speaks.
