I came across this website: http://inputking.com/. It lets you input Japanese (and Chinese and Korean) in a manner similar to IME. Seems OK for people who don't always have the ability to install things on a computer (for example, a work computer). Anybody know of a better alternative, though?

For a brief period some time ago, I couldn't install Japanese IME, so I "bought" a copy of this: http://www.njstar.com/cms/njstar-japanes...-processor

If you can install things, I would just use JWPce.

I just copy+paste stuff.

There's Ajax IME for Japanese. It's been handy more than once.

I'm not aware of any other good online input methods for Chinese or Korean though.

Kitsune Firefox addon. Used it for a good 2 months before getting a torrent of IME. It worked pretty good.

If you want an option for the IME pad:

Thanks for all the suggestions. Much appreciated.

You can try https://www.hiraganakeyboard.com , it's an online Japanese IME that allows typing in romaji and converting the input to hiragana, katakana and kanji.

I just use the built in IME on Google translate.
