Modern Architecture and Design Spaces in Onomichi: A Setouchi Design Pilgrimage
Onomichi has long been celebrated as a nostalgic “temple town,” a place where time slows down among winding hillside alleys, stray cats, and the salty breeze of the Seto Inland Sea. However, in recent years, this coastal gem in Hiroshima Prefecture has undergone a quiet but profound architectural revolution. Today, travelers aren’t just coming for the historic Senkoji Temple; they are arriving to witness a masterclass in how modern design can breathe new life into industrial heritage and traditional Japanese aesthetics.
As the gateway to the world-famous Shimanami Kaido cycling route, Onomichi has become a laboratory for some of Japan’s most renowned architects, including Tadao Ando and Hiroshi Nakamura. The city’s design language is defined by “adaptive reuse”—the art of transforming maritime warehouses and decaying hillside villas into sleek hotels, minimalist cafes, and avant-garde museums. For the design-conscious traveler planning a trip in 2026, Onomichi offers a unique juxtaposition: the rugged, rusted charm of a port town blended with the clean lines of contemporary Japanese minimalism. This guide explores the essential modern design spaces that make Onomichi a must-visit destination in the Setouchi region.
1. The Industrial Rebirth: ONOMICHI U2 and Suppose Design Office
If there is a ground zero for the modern architectural movement in Onomichi, it is **ONOMICHI U2**. Once a massive, derelict maritime warehouse (Prefectural Warehouse No. 2), this space was reimagined by the visionary firm **Suppose Design Office**, led by Makoto Tanijiri and Ai Yoshida. Completed in 2014, it remains a gold standard for industrial adaptive reuse in Japan.
The architectural concept was to create a “town within a building.” Upon entering, visitors are greeted by a cavernous interior where the original high ceilings and rugged concrete pillars are preserved, contrasted with sleek ironwork and warm cedar wood. The space houses **Hotel Cycle**, the first hotel in Japan designed specifically with cyclists in mind, allowing guests to check in while still on their bikes and even hang their cycles on specialized wall racks in their rooms.
Beyond the hotel, U2 features the **Yard Cafe**, the **Kogubaro** bar, and the **Giant Store** bike shop. The “Shima Shop” within the complex is a curated design space selling local Setouchi crafts, high-end denim from the nearby Bingo region, and minimalist homewares. The outdoor boardwalk, which looks out over the Onomichi Channel, is a lesson in urban planning, connecting the industrial interior to the natural beauty of the sea. For any visitor, U2 serves as the perfect introduction to how Onomichi respects its blue-collar roots while embracing a sophisticated, modern future.
2. Spiritual Geometry: The Ribbon Chapel at Bella Vista
Located just a short drive or shuttle ride from the city center in the Urasaki-cho district, the **Ribbon Chapel** is arguably one of the most photographed pieces of modern architecture in Japan. Designed by **Hiroshi Nakamura & NAP**, this wedding chapel is situated on the grounds of the Bella Vista Spa & Marina Onomichi, perched on a hill overlooking the Seto Inland Sea.
The design is a poetic interpretation of marriage. Two spiral staircases wrap around the building, starting from separate locations, winding upward independently, and finally joining at the top to form a single structure. This double-spiral design is not just symbolic; it provides the structural support for the building, eliminating the need for internal columns. The exterior is clad in vertical wooden slats that will weather over time, eventually turning a silver-gray that blends with the coastal landscape.
Even if you aren’t attending a wedding, the chapel is a site of pilgrimage for architecture enthusiasts. The way the structure seems to float among the trees, coupled with the panoramic views of the islands, makes it a transcendent experience. Visitors should note that while the chapel is on private hotel grounds, it can often be viewed from the exterior, and staying at Bella Vista—itself a masterpiece of luxury design—offers full access to the site.
3. Slow Living on the Hillside: LOG by Studio Mumbai
High on the slopes of Onomichi’s iconic hills, tucked away from the main tourist paths, lies **LOG (Lantern Onomichi Garden)**. This project is a fascinating cultural hybrid, born from a collaboration between the local Onomichi community and **Bijoy Jain of Studio Mumbai**, an internationally acclaimed Indian architectural firm.
LOG is a revitalized 1960s apartment complex. Rather than demolishing the structure, Studio Mumbai opted for a “hand-built” renovation process. They used traditional Japanese materials—such as *washi* (hand-crafted paper) and lime plaster—applied with techniques that emphasize the human touch. The result is a space that feels earthy, tactile, and deeply serene.
The building serves as a multi-use facility featuring a boutique hotel, a cafe, a bar, and a shop. The color palette of the walls, a soft dusty pink and sage green, was inspired by the natural light of the Onomichi hills. Staying at LOG is an exercise in “slow travel.” There are no televisions in the rooms; instead, the design encourages guests to observe the play of light on the plaster walls or watch the sunset over the terracotta rooftops of the town below. It is a masterclass in how modern design can prioritize sensory experience over high-tech luxury.
4. Brutalism Meets Nature: The Onomichi City Museum of Art
Perched at the top of Senkoji Park, the **Onomichi City Museum of Art** is a striking example of how modern concrete can harmonize with a lush, green landscape. The original museum was built in 1980, but it was the 2003 renovation and extension by Pritzker Prize-winning architect **Tadao Ando** that transformed it into a world-class design destination.
Ando’s signature style—vast expanses of smooth, unadorned reinforced concrete and large panes of glass—is on full display here. He designed a new wing that sits parallel to the original building, connected by a glass-walled gallery. The genius of the design lies in its transparency; as you walk through the museum, the “borrowed scenery” of the Seto Inland Sea and the historic pagodas of Onomichi are framed like living paintings through Ando’s precise windows.
The museum has also gained internet fame for its “security guards vs. cats” saga, where local felines Ken-chan and Go-chan frequently attempt to enter the museum. This playful element adds a layer of local charm to an otherwise austere architectural space. Visitors should take the Senkoji Ropeway to the top, explore the museum, and then walk down the “Path of Literature” to see how the modern concrete structure anchors the peak of the hill.
5. Floating Perspectives: The PEAK (Senkoji Park Observatory)
In 2022, Onomichi unveiled its latest architectural landmark: **The PEAK**, a new observatory deck at the summit of Senkoji Park. Designed by **Hiroshi Nakamura & NAP** (the same firm behind the Ribbon Chapel), this structure replaced a dated 1970s observation tower with something far more elegant and integrated.
The PEAK is essentially a 63-meter-long bridge that projects out from the hillside. The design was inspired by the way Onomichi’s narrow alleys (*roji*) feel like bridges between the mountains and the sea. By creating a long, linear walkway rather than a circular tower, Nakamura allowed for a “moving” view; as you walk along the deck, the perspective of the islands and the shipping channels constantly shifts.
Architecturally, the structure is remarkably slim, supported by delicate steel columns that minimize the impact on the surrounding forest. The use of wood on the walking surface and railings gives it a warmth that invites visitors to linger. It is fully accessible, featuring a sleek glass elevator that is a design marvel in itself. At night, the bridge is subtly illuminated, appearing to float like a glowing needle above the city lights.
6. Small-Scale Design: Miharashi-tei and Community Renovation
While the large projects like U2 and LOG grab the headlines, Onomichi’s modern design identity is also built on small-scale community renovations. One of the best examples is **Miharashi-tei**, a 100-year-old *villa* that was meticulously restored and turned into a hostel and cafe.
The “Onomichi Akiya Saisei Project” (Onomichi Vacant House Regeneration Project) has been instrumental in this movement. They work with young architects and craftsmen to take abandoned hillside homes and turn them into minimalist guesthouses, art studios, and bakeries. These spaces often retain their original timber frames and clay walls but incorporate modern glass partitions, industrial lighting, and contemporary furniture.
Walking the hills, you might stumble upon **Neko no Hosomichi** (Cat Alley) or small galleries like **Mouhitotsu no Mado**. These spaces represent the “Onomichi Style”—a design philosophy that values the “beautifully aged” over the brand new. For the visitor, these spots offer a more intimate look at how design is being used to prevent urban decay and foster a new generation of creative residents.

FAQ: Planning Your Visit
1. What is the best way to get to Onomichi from Hiroshima or Osaka?
From Hiroshima, take the Shinkansen to Fukuyama Station, then transfer to the local JR Sanyo Line for a 20-minute ride to Onomichi Station. From Osaka, take the Sanyo Shinkansen to Shin-Onomichi Station. Note that Shin-Onomichi is about a 10-minute bus or taxi ride from the waterfront and the main design sites; many travelers prefer taking the Shinkansen to Fukuyama and transferring to the local line to arrive directly at the central Onomichi Station.
2. Is Onomichi walkable, or do I need to rent a car?
Onomichi is exceptionally walkable, particularly the hillside areas and the waterfront where most architecture is located. However, the hills are steep and involve many stairs. To reach the Ribbon Chapel or Bella Vista, you will need a taxi, a rental car, or to check the hotel’s shuttle schedule. For the Shimanami Kaido, renting a bicycle is the preferred method of transport.
3. Can I visit the Ribbon Chapel without staying at the hotel?
Public access to the interior of the Ribbon Chapel is generally restricted to wedding guests or hotel residents to maintain privacy. However, architecture enthusiasts can often view the exterior from the hotel’s public garden areas. It is recommended to call ahead or check the Bella Vista Spa & Marina website for the latest visiting policies.
4. Which design hotel should I choose: Hotel Cycle (U2) or LOG?
Choose **Hotel Cycle** if you want an energetic, industrial vibe, proximity to the train station, and easy access to the start of the Shimanami Kaido. Choose **LOG** if you prefer a secluded, quiet atmosphere, high-concept minimalist interiors, and don’t mind a steep walk up the hillside with your luggage.
5. Do I need to book museum tickets in advance?
For the Onomichi City Museum of Art, advanced booking is usually not required for the permanent collection. However, for special exhibitions, particularly during the Setouchi Triennale seasons or peak spring/autumn travel months in 2026, it is wise to check their official website for timed entry requirements.
