This place isn't so much a museum as a huge gift shop of various pieces of glass. There is a museum tucked away at the back, with an admission price of ¥800, we skipped that.
What is fun though, is the "Workshop" area where you can try your hand at glassblowing and some other glass crafts that are more appropriate for younger kids. It's not particularly cheap (¥3500-4500 per piece), but if you've ever been interested in trying your hand at this it's probably worth the price.
You're more of a helper than an artisan, as the workers do all the more dangerous and difficult work, but you get to blow, and to help the glass. It takes about 20 minutes per piece, and gives you a good first-hand idea of the artistry involved in glass working.
The staff doesn't speak English, so you need to be able to take instruction in Japanese.
Definitely worth the trip.
