I don't know honestly. I have to do some research. I don't know what will grow here. It's cold and dry in the winter, and Japanese houses have little insulation and no central heating, so it's cold inside too. Summers are hot and humid, and we have 6 weeks of steamy rain during June and July.
I'm open to suggestions. I've always bought peppers up until now.
The only hot peppers I've seen here are those small dry Chinese ones. Hot but no real flavor.
