Excellent location, easy to get to from the station. It’s a beautiful ryokan. Onsen with views of the ocean. Staff were very friendly and helpful. It was quiet even though my room was facing the main road. Both breakfast and dinner was excellent. They had a great selection of nihonshu. The staff were well versed in their knowledge of nihonshu and recommended a few to try with my dinner.

Nothing

The outstanding hospitability, courteousness and friendliness of Taiseikan ryokan staff, combined with the esthetically appealing rooms and surroundings make for a delighful stay. The spacious rooms provide perfect comfort and offer magnificient views. Our preferred stay in Japan after many years of steady travelling.

Except the public bath, the Ryokan has another two bath rooms can be used without booking or extra fee, you can go in as long as it's available, and it functions as the private bath. Since Ajiro is not a hot destination compared with Atami or Ito, the private bath is often available. However, Tokyo people like to spent weekend in izu so it's expected to be a bit busy in the weekend. The rooms are very clean and traditional as well. I think it's hard to find another ryokan with same level of comfort with a close price.

The room only has 4 power sockets, all away from sleeping area, made it inconvenient to charge phones, portable wifi, etc. Also it's a bit surprised that such a good ryokan doesn't have microwave oven in the room.

Food, staff, and location. The hotel is not far from the JR station, and it is convenient for people not driving. Staff is nice and attentive to detail. The food, especially the grilled fish, is delicious. This boutique hotel is valued for money given that two private onsen rooms are offered for all guests. I highly recommend this place for people who look for a quiet and relaxing onsen trip.

Very friendly staff, well equipped hotel including private onsen. It’s in a small village reachable by bus from Atami. You can walk along the coast line to some more restaurants

Futon sleeping is not my thing. The beach opposite the hotel is not intended for sunbathing or swimming

We spent 4 nights at the ryokan. At first we were worried that the booking would be too long. However we loved the trip back in time to a sleepy onsen town The banquet for one dinner and one breakfast was outstanding. We made the most of the Atami area and having lived in Japan it made everything easier

Big beautiful clean room Beautiful view on the sea Great onsen Very kind staff Lobby with beautiful vintage fournitures and a bar

It s not thé hôtel’s responsability but it s too bad that the city built the main street just next to the sea and down by the hôtel . Many cars pass by unfortunately . All in all it didnt change our experience - we loved staying there

The view from the private onsen in the 5th floor is really great. The public one with it's outer area was okay. The room was spacious and the futons were soft and cozy. The breakfast was big and full of great seasonal and local produce.

The area around the Ryokan is not so great. Not much open in the evening or are closing down early. If you stay for the night it is better to book a room with a dinner course.

The experience here was incredible. Ajiro is a quaint town and Teiseikan provides a perfect retreat from the woahs of the city. Staff are very helpful, friendly and willing to assist foreign travelers.

The futons are a bit firm.

Very beautiful room with ocean view. Very good public bath. Free access to a private bath on 5th floor with ocean view. Very kind staff.

I forgot to order full board and it wasn't possible to upgrade (which was kinda understandable since I arrived rather late). Luckily there was a very good restaurant less than a five minutes walk away.
