Many thanks for your replies kujiratyan - i've had a look at the websites you've suggested and i'll keep looking out for bands that i like. I'm struggling to find any other bands that might be playing due to the website being in Japanese
but i'm attempting to learn Japanese at the moment (i only know about 500 kanji and hiragana/katakana, but hopefully i'll be able to translate it a bit better soon!).
The little house diagram is cool as well! Are you Japanese or have you moved to live in Japan from somewhere else? I am from the UK.
To Polar: Not one, but two volcanoes erupted on your trip?! That is very unlucky. When did you travel to Japan?
