I was complaining a while ago that there was no Japanese etymological dictionary available on the internet, apart from Starostin's [url]http://starling.rinet.ru/cgi-bin/response.cgi?root=config&morpho=0&basename=\data\alt\japet[/url], which only contains very old words. (I have no idea why the link doesn't work here; just copy and paste it in your browser's address bar.)
But recently I found a more general etymological dictionary: 語源由来辞典 http://gogen-allguide.com/
. It's all in Japanese and it contains only about 2000 words (and growing), but I found it quite interesting. I don't know who's maintaining it and what authority they may have.
The dictionary is accompanied by a place-name etymological dictionary: 地名由来辞典 http://chimei-allguide.com/
. As you may know, just by looking at the kanji a place name is written with, you can never be sure about the actual origins of that name, even when those kanji seem to lead to a very plausible explanation.
