Website for dialect differences

Question

Is there a website where one might find a list or dictionary or difference dialect differences, -not just kansai- or "slang" of certain regions or prefectures?

Answer 1

I have found a couple of links for your reference:

http://www.kansaiben.com/

This appears to hold a list of all dialects in Nihongo:

http://www.nihongoresources.com/language/dialects/kansaiben.html

Hope this helps.

Answer 2

As ssb already commented on your question on main, you're looking for 方言辞典 "dialect dictionaries".

The two online sources I know are

• Weblio 方言
  A fairly comprehensive dictionary, sourced from dictionaries for individual dialects across the web.

• http://dictionary.goo.ne.jp/dialect/
  A free online version of the paper dictionary 全国方言辞典 published by 三省堂 (Sanseidō).
