Tsukuba Onsen KIRARI annex

This onsen has an outdoor bath with natural hot spring water flowing directly from the source, which was one of the highlights of the visit. The water felt very authentic and relaxing. One thing to note is that the crowd information on the official website does not seem to be updated regularly. When I arrived, it was much more crowded than expected, which was a bit surprising. It would be helpful if the congestion information were kept more accurate. I also think it would be nice if facial cleanser were available at the washing area. Another small improvement would be placing a mop on the floor, because many people leave the bathing area without drying themselves off, which made the floor quite wet and slippery. The soft serve ice cream at Kokochi Café was excellent. It tasted very similar to the soft serve from Ministop—rich, creamy, and very satisfying. The “Oropo” (a mix of Oronamin C and Pocari Sweat) was also incredibly refreshing and delicious after the bath. As for the restaurant, the ginger pork was too strongly seasoned for my taste, so I wouldn’t particularly recommend it. However, the oyakodon was outstanding and definitely worth trying. Overall, the hot spring itself was great and very relaxing, and with a few small improvements the experience could be even better.

I had an amazing experience! When I arrived, they had someone who spoke some English help explain the process to me, you leave your shoes in a lock box, get a bracelet that you can buy stuff with. You pick out which size clothes they give to you to walk around in. For an extra 300 yen you can use the hot stone room, you lay on a stone floor with your outfit on and a towel, the room next to it has a cold room with misty air to cool off. To use the onsen you shower at a mini wash area after you leave your clothes in the ladies locker room and take the key. They have several pools to use, some with jets, some with electric shock thing (kinda cool), and outdoor onsens. They have mud masks you can put on and lay down on a slanted stone that streams warm water down your back. They have rest areas, sleep areas, reading material, a sauna, food and I definitely recommend the massage. 90min for 9000yen. Best-massage-I've ever had!! Seen a variety of ages here, don't come here with a tattoo -they are clear about that rule. Best part of my trip so far!!

was my first onsen experience after living in Japan for four years, and now I realize I truly wasted those four years by not coming sooner. It was one of the best experiences I’ve ever had. The public bath offers a great variety, including jet baths, an electric bath, and a herbal bath, along with a sauna and a spacious outdoor area with comfortable relaxing chairs. The facilities are very clean, the wristband payment system is convenient, and towels are included in the entrance fee. The staff are friendly, attentive, and speak English very well, which made the experience even more enjoyable and stress-free.

A wonderful onsen that made me feel relaxed and at peace. This is truly a great location to visit during the cold winter months as the whole place has heated floors. The atmosphere was very relaxing and the food was good too. The wristbands that we received at the shoe locker were convenient as we could use them to purchase any product or service at the onsen. Once you are ready to leave, you can use that same wristband to pay for your stay at the exit machines.

We had a wonderful, relaxing experience. The baths are fantastic and the facilities are very clean. The staff were friendly and welcoming even though we do not speak Japanese. We were there with our 10yo daughter and she also loved the experience. None of us have tattoos, but keep in mind that they have a strict no tattoo policy. Even though we were the only foreigners, we felt welcomed. We had such a great time that ended up coming back the following day!
