Facilities: I have to lament the humanization of Japanese convenience design. There are many toilets and rest seats in the swimming hall. It is very convenient for families with old people and children to rest at any time. There are many hand-washing pools where animals can be directly touched. Apart from introducing little Chinese, the others are very satisfied. Interesting: There are many small animals, which are more than the domestic ones. The whole swimming hall is spiral, first slowly up and then slowly down, up and down you can see no small fish swimming around, the whole is a diversified small ecosystem. But at the entrance, you can buy a small stamped book and find the stamps of the corresponding small animals everywhere. Transportation: It takes less than ten minutes to get off the bus in Osaka. There's a Tianbaoshan Ferris Wheel next to it. It's easy to find.
