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 and takes 5 minutes on foot. 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.
