Unfortunately, most Onsens are rejected tattoos in Japan. However, there is a Tattoo-Friendly open-air Onsen! This is one of the few baths that allow tattoos! ★1★ Let's meet at the station. Woman guide can't take men to men's bath. But she will give you an instruction, so you will not be ashamed of making mistakes. Only the open-air bath, men and women are exchanged depending on the day. Women can be used on even days and men on odd days. If you make a reservation with a couple, one of two will not be able to enter the open-air bath. Instead, can take in a high concentration soda bath. Five indoor baths can be used at any time. There is also a separate open-air wooden deck. Use it naked. It is the best situation to see the Tokyo Sky Tree while relaxing in a hammock when you get hot! ※ Whether you do shampoo or just soak in is up to you. I usually just soak in. ※Weekends are crowded, you may have to wait to get in. ★2★ There is a convenience store nearby. I will buy one drink for each. Let's slowly return to the station.
