Based on Japan having a population of 128 million, and having 98 questions, Wakayama "ought" to have 0.76 questions, and Taiji "ought" to have 0.0025 questions. Granted, the number of tourists a place gets, and the number of questions it gets, isn't strictly proportional to its population, and I've read that Taiji gets a reasonable number of bona fide domestic tourists. But I wouldn't expect a Wakayama tag to get overpopulated.
If a couple of locations in Wakayama got questions asked about them, and they were tagged by their town, leading to several single-use tags for locations within the same prefecture, would that be seen as a a worse outcome than a couple of questions being tagged by prefecture, leading to them using a shared tag?
Should a question specifically about a minor destination like Taiji be tagged by the town, the prefecture (state) it's in, or both?
