I'm not sure, but I think it's to do with the fact that it's settled much more recently. Anyway, Hokkaido is a different class of prefecture than all the rest, and it actually has subprefectures as well, which none of the others do - but overall it has around the same population as the rest of the prefectures. The do in Hokkaido is 道, which usually means "road" - historically, this referred to a region of Japan, so 北海道 (Hokkaidou / north sea road) contrasting with 東海道 (Toukaidou / east sea road, which is no longer used as a prefecture but refers to the region around Nagoya between Tokyo and Osaka) and I think there's a 西海道 (west ~) somewhere.sirdanilot wrote:Why is Hokkaido only one prefecture while the others are smaller?
The other prefectures are mostly known as 県 (ken), but there is also 都 (to), used for the metropolitan prefecture of Tokyo, and 府 (fu), used for the metropolitan prefectures of Kyoto and Osaka, again mostly for historical reasons.
Before the Meiji revolution in the late 1800s, Japan was divided into a different set of provinces, known as 国 (kuni), which also confusingly means country, or 州 (shuu), which is now used for states in America, for example. Many of these match up to modern prefectures (almost all of them have different names, though, like there was Musashi, which covered Tokyo, Saitama and Yokohama), but Hokkaido wasn't colonised by the Japanese at that point, so I don't think it has a matching historical prefecture.
