Wow, you cooked it by yourself!? great.
I never thought about it because in my country (Thailand), it's quite easy to find Japanese stuff here especially in Bangkok. We have Isetan, Tokyu, (Tokai) Max Value/Jusco/Aeon, and tons of Yamazaki. Many Wagashi are made here (that's why it's cheap enough for me to buy it otherwise I can't afford it).
May be you can try this
