Fantastic traditional ryokan near Shimoda! If you want to experience traditional Japanese ryokan vibes, this place is for you. Would definitely stay here again. I loved my stay - so calm and peaceful. The staff was very welcoming and helpful. It has a lovely onsen (both for women and men) which is open late at night, a huge pool which is great for families. The room was extremely neat, and the interior was designed in a traditional Japanese style. The WC was in the room and public showers in onsen, as well as one private onsen with a shower that can be used at night for free (everything super neat). Just keep in mind that this ryokan is slightly out of Shimoda - if you are travelling from Shimoda you have to take a taxi from the train station (around EUR 8-9 one way) or rent a bike. There are some local buses that go to Rendaiji as well. They have a couple of e-bikes on site for rent, however, as I understood, there is a regulation (applied everywhere) that you have to come back with a bike by 5 pm. Rendaiji train station is around 10 min away on foot, or they organise shuttles - thus a great location if you want to explore Izu peninsula more. Note that if you do not take dinner on site, there are not many dinner options nearby, you either have to go to Shimoda or to 7/11 (around 10 min on foot from the property).

Not the hotel's fault, but I booked a massage, and it was of very poor quality and quite pricey.

This felt like a very traditional Japanese experience without being intimidating. The facilities were excellent and although it was winter, we made use of everything including the outside pool.

We had a room only package and food was not included. We did ask if we could add food, however they appeared to be at capacity for food servings so it could not be included. It would have been nice to include food to add to the experience, however it did not detract from the overall enjoyment as we found great restaurants in Shimoda town.

From the moment we arrived, we realized this place was better than what we had expected from the photos. It felt very old-world Japan. It was dignified, polite, sprawling, and comfortable. The onsen were excellent, the gardens were nice to walk through, and staff were very courteous and helpful. We hope to go back.

The bathroom was a bit cold, but we were there in February, and we understand that is normal for Japan... Actually, speaking of the bathroom, the room we had had a bathtub that received hot spring water, which was pretty amazing.

Beautiful ryokan in the small town of Shimoda. The pool, sauna, and onsen were so worth it and made our stay extremely relaxing.

We discovered that breakfast and dinner were a part of the experience at the ryokan. We inquired if we could have for the following night of our two night stay but they said we had to book these experiences in advance. Totally understand but a little more flexibility could be nice!

Everything! Location- easy to find, close to town centre of Shimoda (we were driving) Facilities- it has indoor onsen/public baths , both open and closed. I enjoyed viewing the full cherry blossom tree from the indoor open bath which was a bonus. There’re also outdoor swimming spa and sauna which we didn’t get to use, but they look amazing. Rooms - we stayed at the first floor ryokan. the room was immaculately housekept, has a private bath in the bathroom. Very clean. Housekeeping was excellent, providing the usual excellent Japanese hospitality. Staff - very courteous and making their effort to help even though they speak minimum English.

Our stay was fantastic! The staff was incredibly friendly and professional, making us feel right at home. Our room was huge, complete with our very own private onsen, and the facilities truly left us impressed. We couldn't get enough of the Finnish sauna! We'll be back for another visit.

Nothing at all, everything was truly amazing! We only wish we had opted for a meal-inclusive plan, but it looks like you can only do that by booking directly through their website.

This was a fairly, though not overly traditional ryokan that has exceptional pool, sauna and onsen facilities. Considering the price, you get way more than you pay for. The staff are extremely courteous and attentive.

Didn't actively dislike anything.

This is a beautiful hotel, I had an awesome, super large room with a private bath that I used daily. My room had a river view with tranquil flowing water sounds and forested hills, very beautiful. The staff were super nice and friendly. Tons of spa and pool facilities. Super close to rendaiji station.

Tattoos not allowed in public areas which is no problem if you have a private bath.

Loved having a deep tub and a sitting room in our room. Staff were very helpful and one of the staff members spoke good English and was able to help us when our Japanese wasn't getting there haha! Pool and sauna were exceptional!

This was our first ryokan, and Seiryu-So blew our minds. What a beautiful place. We spent 5 nights, and enjoyed every minte (especially the minutes spent in the onsen!) Thank you for your hospitality, we had an amazing time here.
