A cool cave to walk under in the hot summer. Bring along a front facing light for your phone so that photos taken can be clearer. There will be some dripping water but it’s a lovely and easy long distance walk underground with some stairs n wet floors. The tickets you bought will include the Caves and Kingdom world. After exiting from caves, there will be some shops and glass souvenirs shop. There are glass making experience here and the glass cups ranges from Y2000-Y8000. Design and colours and prices are definitely better than in Onna glass but it’s a small furnace outside the shop. Not sure how long it will take to receive your finished products. However, if you are looking to buy glass cups and glass earrings and necklaces, there are a lot of varieties here at reasonable prices. You can even make n design your own glass pendant. There’s also a cute game store where you get 5 ping pong balls for Y500 and you can get the cups that your ball enters. A great place for must visit for about 2-3 hrs.
