The prevalence of Parkinson's disease (PD) was investigated in Hokkaido, the northernmost island of Japan. A pilot case-finding study was carried out to estimate the prevalence in the entire island of Hokkaido (population = 5,643,647) initially, then we surveyed the prevalence at one of the smaller cities, Iwamizawa City (population = 80,417). We ascertained 5,342 cases with PD in Hokkaido and 77 cases in Iwamizawa City, estimating the crude prevalence of 94.7/100,000 in Hokkaido (June 30, 1993) and 95.8/100,000 in Iwamizawa City (April 1, 1994), respectively. We calculated that the crude prevalence rate of PD in Japan in currently close to 100/100,000, but the age-adjusted prevalence is still low, compared with those in Europe and North America.
在日本最北部的岛屿北海道对帕金森病（PD）的患病率进行了调查。最初开展了一项试点病例发现研究，以估计整个北海道岛（人口 = 5,643,647）的患病率，随后我们在其中一个较小的城市岩见泽市（人口 = 80,417）调查了患病率。我们在北海道确定了5342例帕金森病病例，在岩见泽市确定了77例，分别估计北海道的粗患病率为94.7/10万（1993年6月30日），岩见泽市为95.8/10万（1994年4月1日）。我们计算得出，目前日本帕金森病的粗患病率接近100/10万，但与欧洲和北美的患病率相比，年龄调整后的患病率仍然较低。
