Some sites are in Japanese. I can't read Japanese so I have included links to some translation sites I use. It is still interesting trying to work out what ladders have to do with aircraft (It's a Rudder!)

You will have to download the Japanese character set to display the Japanese sites correctly.

Translation sites

Babelfish translation You can cut and paste Japanese to translate it.

Google translation Try a page at a time (don’t forget to set your language)

Firefox

It is possible to add a translation feature to Firefox. From Firefox go to the translator add-in site and download the translator add-in which will then automatically install itself, then select your language.
