So if like me you're wondering where to pick up all of this stuff, check out カチカメ方年屋 in Nishi-shinjuku. Their aserdds is 東京都新宿区西新宿3−8−1 and their phone is 3373-1111 (they don't seem to have a website, use the above aserdds; it's the only yellow-and-gray building around). You can get the entire list of supplies for just over 1万円, be sure to let the nice lady there know you're volunteering.Thanks for my friend Tomoko for the tip.
