Written by Editorial department

The Seto Inland Sea, Japan’s largest inland sea, is dotted with countless islands and known for its “multi-island beauty.” This time, we are introducing the “Komogakushi Onsen Hotel Sanyo Club,” located on the secluded Iwagi Island in the center of the Seto Inland Sea.

The name “Komogakushi” (“Hidden in Reeds”) comes from a story that tells that a Jizo statue wrapped in reeds once washed up at the cape on the hotel’s grounds.

Charm #1: Ocean View

All of the rooms at beachside Komogakushi Onsen Hotel have ocean views. The lovely view of the Seto Inland Sea is incredibly soothing. Guests can choose their preferred room from Japanese-style, western-style, and suite-style rooms.

All rooms come equipped with bidet toilets.

Select rooms are also pet-friendly! (Only in western-style rooms on the private floor)

Charm #2: Local Healing Hot Spring “Bijin no Yu” (“Beauty Water”)

The best part of the Komogakushi Onsen Hotel is the hot spring (onsen), the water for which is drawn up from 1200 meters underground. The spring water is 31.9 ℃, and contains calcium, sodium, and chloride. This thick, viscous water has a great reputation as “beauty water” that gradually moisturizes skin.

Both the men’s and women’s baths are made with Japanese cypress. It is said that the fragrance of natural Japanese cypress sooths the heart. It is easy to pass the time in the hot springs, watching the sun set over the Tatara Bridge and Seto Inland Sea’s many islands.

Charm #4: A Shore Like That of a Private Beach

Beneath the hotel is a lovely beach with quietly rolling waves. The atmosphere there is relaxing, like that of a private beach. You can enjoy swimming in the beautiful crystal clear blue sea. Another perk is that guests can go directly to the beach in their swimsuits from their rooms.

Charm #5: A Row of 3000 Cherry Trees

Mt. Sekizen, located at the heart of Iwagi Island, is famous for its cherry blossoms. In early April, when the cherry blossoms bloom, 3000 flowering cherry trees form a path that looks almost like the flowing robes of a celestial maiden. The path is great to hike, extending around 6 kilometers between the harbor and the observation deck. Settle down beneath the cherry blossoms for lunch, and take some time to just enjoy the scenery.

Of course, the view is spectacular even when it isn’t the spring season, so you can enjoy hiking throughout the year.
