In Japan there are plenty of traditional hot springs, the most common are called Onsen (温泉). This time I will talk in a more fun way to enjoy the hot springs.
Hakone Kowaki Yunessun (箱根小涌園ユネッサン) is a hot springs spa resort and water amusement park located in Hakone. In this resort are a lot of recreations of Onsen with various decorations or environments, and other natural Onsen, pools or waterslides.
In traditional Onsen has to go naked and thus normally men and women are separated in different places, but in Yunessun as we are allowed to wear swimsuit, we can enjoy together. If we also have a tattoo, we can cover it with clothing (because in the Onsen it is not allowed to enter with tattoos).
Some of the most striking types of hot springs in Yunessun are where the water that simulates wine, tea, coffee or even sake (Japanese liquor).
We can also buy food, play games machines or dare to be treated by Dr. Fish, one of the most amazing experiences that Yunessun offers.
