DTC - thanks for the nice comments. I live near Tokyo Tower so about 1 1/2 by car to Shonan ( parking is $7 for 1 hour in the summer ) and 2 1/2 to Chiba ( toll roads is $30 one way ) The photos are from Mr. Saikai's website called STARBOARD
http://starb.on.coocan.jp/. He shoots Kugenuma beach ( sometimes Kamakura ) everyday twice a day.
To answer your question why I hate Nose Concave, is it creates an air bubble to support you while on the nose BUT it also makes the board harder to paddle. Concave helps lock in the nose , but I like the nose to slide around a bit. If you put concave make it very very slight, not those big tear drop outlined types. If you are on the heavy side it's more useful, but if you are feather weight, it just bucks you off. It is more important to LOCK the tail with the rail, than rely on a big fin or big nose , or deep concave. On 1-16-2014 I write about the secret to noseriding.
Thanks for checking my blog.
