There are a few points around Enoshima, directly on the beach at Enoshima is hard as often tourists are on the beach. The wind here is often not perfect, and fairly light, possibly due to the location and the island.
There is a second beach further along which Pure tends to use.
Great little spot. It has a North and a South side to this so it catches most of these winds as always directly on-shore.
The South Side of the beach often has really large swell, being that its ocean facing. This can make getting out past the break hard - body dragging out past it is the most effective. The beach is very wide but the water quickly becomes deep. During summer the beach is split into regions, and kiters should keep further up the beach towards the tip. Parking can be done on the lane just behind the beach.
The North side is very shallow with sand banks often appearing at low tide. The beach itself is fairly wide with an access road right onto the beach.
Fairly small spot, great for Notherly winds or cross E/W winds. Very superb thermals in the late afternoon during summer. However, there are a few casual bystanders and it doesnt take much to end up stuck on the cement harbor walls. Take care here.
The closest shop is real, just behind the Makuhari Messe hall.
This is an artificially made beach just outside Yokohama. As such it has a lot of man made structures, but has a wide beach with shallow water. Technically not an offical spot, this is kitable if you are desperate.
There is a windsurf locker and facilities for shower here. BUT please respect the wind surfers rights as they were here first. Since it is a controlled space its possible you might be told to leave, so respect the signs and take care of saftey above all.
The surrounding landscape creates great turbulence, and at times of the year (summer) there are too many land-lovers, traps, and buoys which make it impossible to kite. Winter is the best time.
Night time is possible given the illumination from surrounding area - if you are mad enough.
Almost got in a punch up there, I was told to leave as its a "Wind surfer only" beach. Shame we cant all get along.
