> At the beginning, I used to do everything manually:
> - I downloaded a region in JOSM
> - I found the stations with missing attributes
> - most of the time, the japanese name was present, so I used it to find
> the japanese wikipedia page (by just adding 駅 / "station" at the end of
> the name)
> - then I completed the names fields (romaji, english, french, kana,
> name) if needed. I also looked at the english page because the romaji
> name was sometimes better there (long vowels written with a macron)
> 
> It was quite long, so I automated the task:
> - I still have to download the stations in JOSM (using the relations
> saves a lot of time)
> - I export that to an XML
> - I find the nodes being a station
> - if a romaji name is present (romaji, english, french), I use it to
> complete the others
> - I download the Japanese and English Wikipedia pages and extract the
> info
> - I complete the missing attributes
> - I put the modified node into another XML
> - I open it in JOSM
> - Double-check manually that it looks fine and commit Note that it does
> not handle the disambiguation pages (when two stations have the same
> name). And it is not really clean at it is done by extracting data from
> HTML.

Wouldn't any Wikipedia information be under CC BY-SA and therefore unsuitable for importing?
