Otaru dream beach is not the cleanest or nicest beach in the world, but closest to Sapporo, and therefore most popular and most crowded. It has a large parking lot (which costs 800 yen during beach season) and many yakuza run beach houses line the ocean. At dream beach one can ride a banana boat, rent a sunbathing lounge chair, an inflatable toy or even buy a beer. Good place if you want to catch some sun but don’t have time to drive all the way to Ranshima.
