Iwaso

What Iwaso does

Iwaso is a traditional Japanese ryokan (inn) operating since 1854 on Miyajima Island in Hatsukaichi City, Hiroshima Prefecture, Japan, under the privately held corporate entity Ituki Kanko Co., Ltd. (伊都岐観光株式会社). The property is located in Momijidani Valley within the Setonaikai National Park, a UNESCO World Cultural Heritage Site, and within walking distance of Itsukushima Shrine. The asset base consists of 38 guest rooms across three structures: five traditional Japanese-style rooms in the historic Honkan main building, 30 modern Japanese-style rooms in the five-story Shinkan annex built in 1981, and four detached wooden Hanare cottages constructed between 1924 and 1952. Total guest capacity is approximately 100.

Core services include accommodation with full-board kaiseki cuisine (dinner and breakfast) prepared by a Kyoto-trained chef, bathing in the Wakamiya Onsen (a rare radon hot spring discovered in 1885 and the only onsen on the island), and traditional Japanese wedding ceremonies and banquets held in the 115-tatami Kangen hall and at Itsukushima Shrine. The kitchen holds a Michelin 1-star rating, the only such recognition on Miyajima. Iwaso is also credited with originating Momiji-manju (maple leaf bun) in approximately 1906.

The business operates on a direct-to-consumer model with bookings accepted up to 10 months in advance through the official website (with English and Japanese versions), phone reservations, and email inquiries. Pricing is quote-based and not publicly disclosed, with the company stating that direct website booking offers the best rate compared to phone or third-party channels. Cancellation terms are tiered (free up to 4 days prior; 30% at 3 days; 50% the day before; 100% same day). Ancillary revenue includes wedding venue rentals and event hosting, including working dinners for the 2016 G7 Foreign Ministers' Summit and the 2023 G7 Hiroshima Summit. Marketing is conducted through the official website, email newsletter, Instagram, Facebook, blog content, and downloadable brochures, with no third-party OTA distribution as a primary channel. In April 2024, Iwaso opened a BEAMS JAPAN MIYAJIMA retail shop in its Sakura Annex, marking a collaboration between the traditional ryokan and a contemporary Japanese lifestyle brand.
