Rainbow Hills Country Club

Rainbow Hills Country Club's West-North course occupies terrain in Choshi, a coastal city at the easternmost point of the Kanto region in Chiba Prefecture. The course was designed by Izumi Ikkai and Izumi Michio, who worked during Japan's significant golf course development period in the latter half of the twentieth century. The Izumi family represents a notable lineage in Japanese golf architecture, with multiple generations contributing to course design across the country. The routing takes advantage of the rolling topography characteristic of this part of Chiba, where the landscape transitions between agricultural land and coastal elevations. Choshi's position on the Pacific coast means the course experiences maritime influences, with winds that can affect play and vegetation adapted to the seaside environment. The design reflects the Japanese approach to golf architecture from this era, which often emphasized strategic bunkering, thoughtful green complexes, and integration with the natural contours of the land. Rainbow Hills operates as a members' club within the Japanese country club tradition, where golf is typically combined with substantial clubhouse facilities and dining services. The club features multiple courses, with the West-North representing one configuration within the larger property. The setting provides views across the surrounding Choshi landscape, and the course serves the regional golfing community in this part of northern Chiba Prefecture.
