As a local, I often use American Shooters' indoor range. If you go during off hours during the week, it can be near-empty, which is great. The range masters are polite and helpful. But DO NOT buy guns here! Their prices are expensive to the point of absurdity---$150-$200 more than other shops in town. I also found some of the gun store folks a bit rude and pushy. If you are shopping for guns, The Gun Store on Tropicana is a much better choice. One big plus: the have range rules in Japanese and I saw a Japanese speaking range master there more than once.
Pros: Decent shooting range
Cons: The gun prices
