Can 国体 refer to "prefectural" as well as "national"? If `` is used in conjunction with a prefecture name like , does that mean "The National Athletic Meet that is being held in Yamaguchi", or the "The Yamaguchi Prefectural Athletic Meet"? The only definition I can find for `` (in the context of a sports meet) is that it's the _National_ Athletic Meet (goo), but `` can have a meaning of "region" or "hometown" as well as "nation" (goo), so I'm unsure as to what it can mean in this context.

As the dictionary says, in this context is an abbreviation of (National Sports Festival). means the National Sports Festival held in Yamaguchi, in the same way as “London Olympics” means the Olympic Games held in London.
