Asahi

This is a day-trip hot spring facility located along National Route 1 at AsobiX Asahi. The parking lot is shared with AsobiX and can accommodate over 150 cars. [Opening Hours] Weekdays 10:00 AM - 12:00 AM, Weekends and Holidays 9:00 AM - 12:00 AM [Price] ¥800 Amenities such as towels and toothbrushes can be purchased at the ticket vending machine, but they can also be purchased from vending machines in the changing room. The changing room is spacious and equipped with coin lockers (¥100 refundable), beverage vending machines, tanning machines (¥500 for 10 minutes and up), scales, and hair dryers. There is a cold water dispenser immediately upon entering the bathing area. The main bath area includes a washing area, standing bath, natural hot spring indoor bath, carbonated bath, sauna (around 90℃), and cold bath (around 12.8℃). Outdoors, there is an event bath, three individual tubs, an open-air rock bath, a relaxation area, and a body scrub room. The washing area is equipped with rinse-in shampoo and body soap. The hot spring water is circulated and chlorinated, without heating or adding water. It is pale yellow and almost tasteless. The water at the spout has a sulfurous smell, and the bath itself has a mineral smell. The water feels very warming. I didn't notice any chlorine smell in any of the baths. The standing bath is 1.2m deep, and you can feel the water pressure on your body. There are about four jets. Also, for some reason, there is a monkey bar (ladder) above, and I wonder if it's actually for exercise. The floor is a little slippery. The water temperature in the carbonated bath is about 36℃ according to the thermometer, and the others are about 40℃, allowing for a relaxing soak. The pot-shaped bath has mineral deposits floating in it. The event bath during my visit was "Sudachi-scented bath" (a blend of lemon and grapefruit juice), which was green in color and had a pleasant scent. The sauna room is spacious and can accommodate about 20 people. In addition to the large public bath, the hotel also has a restaurant, a shop, and a rest area with a large selection of manga comics, so you can relax and enjoy your stay.

Visited Asahi no Yu on June 13, 2025. This day-trip hot spring facility is located in a section of a mall surrounding National Route 1, where supermarkets, restaurants, electronics stores, amusement parks, and 24-hour gas stations are lined up. The natural hot spring water is a slightly thick saline spring. It's relatively inexpensive compared to the surrounding area, and there are a variety of baths, a spacious sauna, and a semi-outdoor bathing area where you can relax even on rainy days. Open 10:00-24:00 (9:00-24:00 on holidays), with registration closing 30 minutes before closing. Adults pay 800 yen; cash, credit cards, and electronic code payments accepted. Shoe lockers are free, and changing and valuables lockers cost 100 yen and require a return. Amenities include body soap, rinse-in shampoo, a hair dryer, and a water dispenser. (The soapland is a cheaper version of Phoenix.) The indoor bathing area includes a 41°C main bath, a 37°C carbonated spring, a standing bath, a dry sauna, a steam sauna (women's only), a cold bath, a semi-outdoor open-air rock bath, a refillable bath, three tub baths, a tatami shell drying area, and an open-air bathing area with about six chairs. The water is a hypotonic, weakly alkaline, high-temperature sodium chloride spring. It is colorless, transparent, slightly salty, and odorless. There is a slight hint of mineral deposits and slime. The water temperature is 45.8°C, pH 8.2, and dissolved solids are 2220mg. The facility also features a tatami rest area, a dining area, massage machines, and a manga corner. The dining area is open from 11:30 AM to 10:00 PM (last orders 9:30 PM). While I wasn't able to try it this time, the ochazuke (rice with green tea) set looked healthy and delicious.

This was my first visit. I went on a weekday. The shoe lockers are a little far from the shoe-taking area. The shoe lockers are free. It cost 800 yen in cash from the ticket machine. Lockers are 100 yen, but returnable. There are plenty of washing areas, and the showers can be left running. They have a decent amount of power. There are two indoor baths with different temperatures. Neither the indoor nor outdoor baths are particularly large. There are a decent number of chairs for outdoor bathing and places to rest. The outdoor event bath was covered in grime, which put me off. The sauna was spacious and quite hot. However, there were no sauna mats, so many people brought their own. The rest area is spacious and relaxing.

I went to Asahi no Yu after work in the evening for dinner. The staff were very polite and welcoming, and I felt very comfortable. The hot springs were varied, including a jacuzzi, carbonated bath, sauna, and open-air bath, so I was able to spend a relaxing time. There was also a rest area, manga, and a smoking area, which was nice. For dinner, I ordered the horse mackerel fry set, which was just the right amount, and the food was delicious overall. I appreciate the friendly service of the female staff. I'll definitely be back again♪ I wish they had more souvenirs♬

Unfortunately not tattoo friendly but they did give us our money back. If you are foreign it may not be the place for you. Apparently they let in Japanese with larger tattoos just not foreigners. So actually the staff are just racist.
