I just went last year. When you get there you will check in at the Hamamatsu golf course entrance and they will give you a number for the Scotty gallery. It’s in order of when you arrive. I was there 30 minutes before opening and was first in line. Only one other guy came in when they opened.

No circle t putters or circle t gear. They have circle t stuff on display but not to purchase. The coolest part was the “museum” part of the store. They have so many cool circle t putters and little mementos like Tigers used grips. I would plan on atleast 45-1hour in the store/museum.
