Yamanashi is located west of Tokyo and is easily accessible from the city centre. There are various theories such as that the origin of the prefecture's name is that it was because a lot of fruit yama pears were harvested, and that it comes from the "mountain leveling" that leveled the mountains and made them flat, but in fact it is not a "mountain-free prefecture" but a "mountain-free prefecture". About 86 percent of the total area is mountainous. Therefore, golf courses often have a strategically rich layout that takes advantage of the natural terrain. There are many golf courses along the Chuo Expressway connecting Tokyo and Yamanashi and along the Fujiyoshida Line connecting the Otsuki Interchange and the Kawaguchiko Interchange.
Golf courses in Yamanashi are easily accessible by car via the Chuo Expressway. In recent years, the extension of the Ken-O Expressway has made it possible to easily access the courses from Kanagawa and Saitama via Hachioji Junction, attracting golfers from a wide area. For train access, the JR Chuo Main Line runs along roughly the same route as the Chuo Expressway, and the Fujikyu Line runs along roughly the same route as the Fujiyoshida Line, and some golf courses offer club buses to pick you up and drop you off at the nearest station.
Golf courses in Yamanashi are generally built in mountainous areas, so despite being close to central Tokyo, they are at high altitudes, making it appealing to play in cool weather even in the summer. Otsuki Garden Golf Club is conveniently located about 14 kilometers from the Otsuki Interchange on the Chuo Expressway and about 11 kilometers from the Tsuru Interchange on the Fujiyoshida Line, yet it is located at an average altitude of about 600 meters, making it popular with golfers who want to play in a refreshing cool climate.
