Other Thoughts:
This course is located in the heart of downtown Tokyo. It's probably the most simple course I've played yet in the greater Tokyo area. The biggest thing I disliked about course was how small of an area the course is crammed in. I was almost hit many times because my next teepad was literally 15 feet behind or next to the previous basket. Course designs like this piss me off because I feel like I'm always in some idiot's crosshairs.
They conduct a local league event twice a month, the fourth Sunday @ 10 AM and the third Saturday @ 9 AM. I hear the course is much more fun when they use alt tees for league.
Directions from the subway:
From Tatsumi Station take exit #2, walk across the pedestrian sky bridge, hug the road you just crossed and walk north. After walking around 100 - 200 meters north on the sidewalk you'll see the park on the right.
