GeoNLP is a project operated by National Institute of Informatics (Q4346622) which aims to enable us to get location info from place names. It contains so many places including sub-municipality level divisions (ōaza (Q424857)), so I think it will be useful for wikidata.

Since this database is a set of dictionaries, some entries are duplicated. For example, a school may have two IDs, one as a educational institution, another as a evacuation center. In another case, People's Republic of China (Q148) has two IDs, because in Japanese, it is called both '中国' (China) and '中華人民共和国' (Republic of China), and each has its corresponding ID. So it might be better to permit an item to have multiple values, using qualifiers applies to part (P518) or applies to name (P5168). --何三(S) (talk) 16:47, 21 June 2018 (UTC)
