Cold in November to February, but riding possible. Nice from June to September. Warm water, no wetsuit needed in summer.

Recommended wind for kitesurfing is wind coming from S and SSW .

There is Thermal wind at Honshu / Kemigawahama, Japan.

Frequently 5-12 m/s afternoon thermals out of the S, SW. Gusty on anything with any north or much east to it. One of the more consistent spots in summer due to thermals out of the SW off of Tokyo Bay. Almost guaranteed afternoon wind on a sunny summer day. Prevailing thermal is almost directly onshore, so you need to be competent at staying upwind to have fun here.

Wind usually blows from S, SSW and SW on the spot.

Honshu / Kemigawahama, Japan is a Chop spot.

The launching/landing area is reported to be of Medium size.

There is grass to rig up on, beach is wide enough for launch, though there are a fair amount of rocks, sticks to get in your lines. Beach can get somewhat crowded with kites, so rig up, launch and get out in the water.

The water is the north end of Tokyo Bay, surrounded on either side by steel and chemical plants, hence the nickname, `Chemicalgawahama`. But it is the closest beach to downtown Tokyo, so it is used frequently. The riding area is enclosed between two breakwaters and part of the beach is concrete embankment (wear a helmet).
