What we dropped
| Property | Verdict | Why |
|---|---|---|
| Hanare Oyado Yumenoya | Runner-up (81/100) | Scored 81. The food and room scores are very high, but the price sits above the median of the inns we compared, which cost it on value. |
| Hana no Mori Clarice | Runner-up (76/100) | Scored 76. A weeknight costs about ¥40,000 per person, 158% of the median of the eight we compared, which cost it on value. |
| Bettei Kuro | Runner-up (74/100) | Scored 74. A weeknight costs about ¥40,000 to ¥42,000 per person, which cost it on value, and 61 reviews is the lowest count of the eight. |
| Oyado Uchiyama | Another guide | 4.98 across 469 reviews with a bath in every room, but it sits in a higher price band than these five and already appears among the candidates in our in-room dinner guide. |
| Corte Largo Izukogen | Another guide | All seven rooms have a natural hot-spring open-air bath, but it is in our Izu Kogen in-room dinner guide, so we did not repeat it. |
| La Belle Equipe | Passed over | 5 out of 5 across 142 reviews and it meets the theme, but its weeknight price stands well above the rest of the candidates. |
| Regina Resort Izu Muurin | Below the floor | Every room has an open-air bath, but with 5 reviews it is short of our floor of 30. |
Questions visitors ask
Which Izu Kogen inns have a private open-air bath with a sea view?
White Princess says every room has a sea-view natural hot-spring open-air bath and terrace. Shizenya Haco also describes a full sea view. At Kaedean the price varies with the view, and you ask by phone for a room with a better one.
Can I eat dinner in my room?
Rakuten lists the guest room as a dinner venue at Kaedean, Shizenya Haco and White Princess. Kaedean and White Princess also list a restaurant and Haco a private room, so check the plan. Suigetsu serves in a private dining room and Kazeyobi in the dining room.
Can I bring children?
Suigetsu does not accept guests under 18. The notes for the other four give no age limit, but ask about room capacity and children’s rates when you book.
Which is easiest without a car?
Suigetsu is about 15 minutes on foot from Izukogen station, or 5 by taxi. Kaedean is 5 minutes by taxi. Shizenya Haco has a pick-up from Futo station, which must be reserved.
Can I pay by card?
Rakuten shows that White Princess does not take credit cards. Kaedean, Haco, Suigetsu and Kazeyobi list accepted cards. At Haco, on-site card payment is single-instalment only, and the inn recommends paying in advance.
