Wakasu(若洲?) also Wakasu Island, is an island located in Koto, Tokyo. Wakasu, like many other areas of Tokyo, is manmade. 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 a golf course and a popular camping ground.
The 18-hole golf course and the campground attract many people from all over Tokyo.
