Wakasu, like many other areas of Tokyo, is reclaimed land. Save for the camping ground, Wakasu was constructed on a base of trash, a form of land reclamation common in Japan.
Roughly half of the island is an industrial zone, while the other half contains the Wakasu Seaside Park Wakasu Golf Course and a popular camping ground. There is also a large wind turbine located nearby the golf course. The 18-hole golf course and the campground attract many people from all over Tokyo.
