HOW TO: Find hydrogen peroxide in Japan

I don't know about you, but I hate mold. No, hate. Normally, I try not to use such strong, definitive words, but sometimes it seems that mold's mission in life is to torment me. It grows everywhere without abandon, laughing, when I take a shower in the morning. It takes over my newly bought produce, causing me to mourn in anguish as I fill our garbage bag with whole fruit and veggies. It even goes so far as to mount attacks against my body, causing my sinuses to produce much more liquid than what seems humanly possible, sometimes rendering me incapable of walking in a straight line.

I counteract it with what I can - antihistamines, nasal sprays, dehumidifiers, fans, vinegar, lemons, hydrogen peroxide, husband labor, machetes, grenades...

Mold and I are at full-out war.
