A cool little park that's a 12 minute train ride from Nagoya and just a 20 min walk from the station. The park has also just celebrated its 2nd birthday this month (July 2012).
The bowl is 1.4m and 1.7m deep with a 300mm extension in the deep end.
There is a mini ramp at 1.1m high and 3.6m wide and a minimini ramp at 0.8m high and 2.4m wide.
The company that made the bowl and the ramps did a really good job with the limited space they had to squeeze it into the unit. The minis are small but still fun to skate and after you work out the lines in the bowl you can fairly rip around.
The guys that built it are rampshop.com and they built the Nike (miyashita) skatepark in Tokyo.
There is a convenience store 2 minutes walk away and the usual drinks vending machine right outside with the local super market just 10 minutes walk away for a bigger variety of food. All the locals are really friendly and there are a lot of visiting skaters from various teams and shops from around japan all the time. Once a month on a Sunday there is a beginners group on a Sunday till 1pmish and sometime a shop will book out the whole morning. Apart from arriving first in the morning there is usually always another skater there and some even come for a skate in their lunch time.
The only down side for some people maybe that helmets are compulsory and if you don't have one on you, you can rent.
Here is the last jam comp before the extension was added. I'm in there about 1:55
Finding the place is fairly simple and if your in the Nagoya area well worth the visit. The only down side is that it does get hot in the summer so best to take some water with you.
