Dogo Island Hot Spring, Shizuoka Prefecture | Complete Guide to the West Izu Hot Spring Resort Known for Spectacular Open-Air Baths and Skin-Beautifying Waters
Dogo Island Hot Spring, located in Nishi-Izu Town, Kamo District, Shizuoka Prefecture, is a renowned scenic hot spring resort in West Izu that attracts numerous tourists. It is a perfect fusion of unique coastal landscapes, including Sanshiro Island, and high-quality hot spring waters with skin-beautifying effects—truly a hot spring destination where spectacular views and healing converge.
History and Origins of Dogo Island Hot Spring
The history of Dogo Island Hot Spring is relatively recent compared to other hot springs in Izu. It is said to have begun in 1962 (Showa 37), when Saburo Komatsuhara, the founder of Dogo Island Hot Spring Hotel, successfully drilled the first hot spring.
Before this, Dogo Island was known as a scenic spot called “the Matsushima of Izu,” but the emergence of hot springs further enhanced its appeal as a tourist destination. The hot spring water that emerged from the coastline proved ideal for open-air baths that take advantage of the natural landscape, and today many inns feature spectacular open-air baths of which they are proud.
More than 60 years have passed since the opening of the hot spring. Dogo Island Hot Spring has developed into a leading hot spring resort in West Izu and has become one of the most popular hot spring tourist destinations on the Izu Peninsula.

Charm and Characteristics of Dogo Island Hot Spring
Spectacular Open-Air Baths
The greatest attraction of Dogo Island Hot Spring is, without question, the open-air baths with stunning views. Bathing while gazing at the magnificent Suruga Bay, the unique silhouette of Sanshiro Island, and the varied terrain of a ria coast is truly a moment of bliss.
Bathing at dusk is particularly special, and bathing in the hot spring while watching the sunset sink into Suruga Bay is praised by many guests as “the best hot spring experience of a lifetime.” Bathing while listening to the sound of waves and feeling the sea breeze allows you to forget the hustle and bustle of daily life.
Sanshiro Island and the Tombolo Phenomenon
Sanshiro Island, the symbol of Dogo Island, offers the perfect view while soaking in hot spring waters. The island is named “Sanshiro” (three or four sons) because it appears as three or four islands depending on the viewing angle.
