Here’s a very useful link when you’re trying to figure out how to put your aircon on heating mode! It’s a life saver.

There’s also a list of toilet related vocabulary, which ought to be useful some day: http://www.neverland.to/kanji/list/toilet.html

And you’ll find pictures of common kanji found on rice cookers, aircon, or washing machine. This is great if you live here, but can also be useful if you don’t live in Japan but bought a japanese rice cooker.
