Very Popular***** not too much chance of getting it without a crowd because of the following reasons: Easy access from everywhere (especially for Shonan surfers) big local town, big local hospital (surfing nurses line up to work here), works well in lots of wind and swell conditions.

The beach breaks are all similar, with different bottom contours and shore features offering quality waves in the right conditions. The breaks near the car parks are often busy however if you are prepared to walk a bit you will find peaks with a lot fewer surfers. Last Saturday (23/10/2010) morning we surfed a peak 250m from the main carpark with just us for first 45 minutes while the carpark break had 50 surfers on it with the same wave shape and frequency.

The Reef is called Maruki and is one of the four famous Chiba reefs and one of the two lefthanders (goofy waves). It can hold up to solid 3 x overhead and when it get to this size the rest of the beach is closing out. When it is much smaller in the overhead range it difficult to tell that the wave is even breaking over a sandy reef (other than the paddle out is right beside protruding rocks)

With decent size in the swell, 2.5 ~ 4m out of the NE the reef with start to fire up and can be an excellent walling wave.
