Onjuku Beach surf guide
Surf: Not the place for NE swells but a S up to headhigh should see some pretty peaks for the packs of party people who can get on the train in Tokyo and step off onto the beach in around an hour. This means you will get all types of surfcraft piloted (or not!) by a wide range of surfing abilities. To escape the throng, there are some reefy peaks to the east of the harbour, but they take some effort to get to.
Environment: For such a popular destination there is of course plenty of accommodation and restaurants to cater to the thick crowds of August.
