Pros:
The park is beautiful and so is the course. There is a mix of dogleg lefts and dogleg rights.
Cons:
There are no holes where you get to let loose with your distance drivers. The whole course could be played with a midrange disc. The front nine is a joke. There are some very technical holes on the front but they are just too short(the first hole is about 110 feet).
Other Thoughts:
It is worth playing if you are in Tokyo because they don't have much to choose from and the park that the course is in is incredible. On the other hand, the course is very short, and very wooded.
Also, bring your own discs if you want to play. The girl at the rental counter tried to rent me four 150 class putters. Thank god there was somebody on the course that let me borrow a few disks (roc, yeti aviar, and a crow). You wont need anything more than a midrange and unless you are playing in a comp, don't worry about the weight.
