Cool accessories from Japan for my C750?

[Xumbi]

A friend of mine is heading over to Japan in a couple weeks, and I was wondering what accessories I should ask him pick up for my C750.

My signature shows everything that I currently have.

Cases?  Cards?  Screen protectors?  What are some cool accessories that can be found in Japan?

My advice :

Pentopia stylus
An USB -Charge/sync retractable cable
An additionnal battery (the big one EA-BL08K).
the remote control (for sound player)

I bought a leather case but I don't use it (not really practicle).prefer a nylon one.
