Onoso, an Accommodation Specializing in Spiny Lobster and Abalone

Chiba Prefecture／Isumi District
¥33,000～
No meals ; 2 peopleTax included¥32,340〜
(USD 202.96)

We completed a major renovation in March 2026.

Onosou is an Accommodation founded by the previous generation of a diver, with the wish to share delicious local ingredients such as spiny lobster and abalone with many people. That spirit lives on today, and we continue to serve dishes made with locally sourced ingredients. Step away from the bustle of everyday life and enjoy our signature meals in Onjuku, where time flows gently and local flavors abound. Our enchanting bath to soothe travel fatigue features Onjuku’s natural brown-hued Onsen, “Bijin-no-Yu,” known for helping relieve fatigue and sensitivity to cold. You can also relax and lose track of time in our bath area produced by special effects sculptor and decorator “Katsu”. The main beach with Onjuku’s white sand is just a 1-minute walk away.
