lol thats probably a good move. Could you touch them / did any of them play on your camera equipment? I know in some places they're very accustom to people.

I did not get close enough to touch them; they would probably take the equipment and throw it into the water !

Ugh I hope I can go see them some day, they sound hilarious and are awesome. Do you need to speak Japanese to navigate Japan or is it possible as an english speaker?

No you dont need to speak Japanese. There is a lot of english in Japan now.
