Senjokaku Hall Miyajima: The Massive Tatami Pavilion Overlooking the Torii Gate

Why Senjokaku Is Worth the Climb

Most visitors to Miyajima Island head straight for Itsukushima Shrine and its floating torii gate — and then leave. What many miss is one of the island's most impressive buildings, sitting on the hill directly above the shrine: Senjokaku (千畳閣), the Hall of a Thousand Tatami Mats.

Senjokaku is a massive open-air wooden pavilion with no walls and no ceiling. It was commissioned in 1587 by Toyotomi Hideyoshi (豊臣秀吉), one of Japan's three great unifiers, and left permanently unfinished after his death in 1598. The result is unlike any other building you'll encounter in Japan — a cavernous timber-frame hall open to the wind, where massive wooden pillars and beams stand exposed against the sky. According to the Toyokuni Shrine official site, the hall's floor area spans approximately 857 tatami mats, making it the largest wooden building on Miyajima.

The climb takes 15-20 minutes from the ferry terminal, and the admission is ¥100 (~$0.70). For the scale of what you see — and the hilltop views of the torii gate and island below — it is one of the best-value attractions in the Hiroshima area. Senjokaku is part of the broader Hiroshima city guide and is among the recommended things to do in Hiroshima.

History: Hideyoshi's Unfinished Hall

Senjokaku's formal name is Toyokuni Shrine (豊国神社), and it is dedicated to Toyotomi Hideyoshi himself. According to the Toyokuni Shrine official site, Hideyoshi ordered the construction in 1587 as a Buddhist sutra-chanting hall — a place where monks would recite sutras for soldiers who had died in battle.

Hideyoshi was at the height of his power when he commissioned the hall. He had unified Japan through a combination of military campaigns and political alliances, and his building projects — including Osaka Castle — were statements of authority as much as they were functional structures.

But Hideyoshi died in 1598, and the hall was never completed. No walls were added, no ceiling was installed, and the massive timber frame was left exposed to the elements. The Tokugawa shogunate, which took power after Hideyoshi's death, had no interest in finishing a rival's project. The result is a building frozen in time — structurally sound but deliberately incomplete for over four centuries.

Senjokaku was designated an Important Cultural Property (重要文化財) by the Japanese government, recognizing both its historical significance and its architectural value as a rare example of late 16th-century construction.

Inside the Hall of a Thousand Tatami Mats

Architecture and Construction

Stepping into Senjokaku is an unusual experience. The space is enormous — the equivalent of 857 tatami mats — but instead of enclosed rooms, you stand in a vast open pavilion with massive wooden pillars supporting the roof above and nothing but air on the sides.

The timber construction is heavy and muscular. The pillars and beams were built to support walls and a ceiling that never arrived, so the structural elements are overbuilt for their current purpose — which gives the hall a sense of weight and permanence despite its openness. The wooden floor is polished by centuries of foot traffic, and the exposed roof beams show the craftsmanship of late Momoyama-period carpentry.

Because there are no walls, the hall is naturally ventilated. In summer, the breeze flowing through the open structure makes it one of the most comfortable spots on the island. In winter, the lack of walls means it can be cold — dress accordingly.

What You Can See Inside

The interior houses several items worth noting:

• Paintings and calligraphy from other island buildings, hung from the beams and pillars
• Wooden ema (votive tablets) of unusual size, donated over the centuries by visitors and pilgrims
• A historical measuring pillar that was used to take measurements for the torii gate reconstruction in 1873, according to local historical sources

The hall functions partly as a museum and partly as a place to simply sit and take in the space. Unlike most Japanese temples and shrines, there is no prescribed route — you are free to walk around, sit on the wooden floor, and look out through the open sides at the surrounding trees and the island below.

The Five-Story Pagoda

Directly adjacent to Senjokaku stands the five-story pagoda (五重塔), a 27.6-meter tower that predates the hall by over a century. Originally built in 1407 and rebuilt in 1533, the pagoda blends Japanese and Chinese architectural elements — a combination visible in the bracketing and roof curvature.

The pagoda is earthquake-resistant due to a unique structural design: the central pillar extends only to the second floor rather than running the full height, which allows the floors to flex independently during tremors. This engineering approach was ahead of its time and remains a subject of architectural study.

The pagoda interior is not open to the public — you can only view the exterior. However, the exterior is photogenic and the pagoda's position next to Senjokaku, framed by trees and the island landscape, creates one of Miyajima's most distinctive compositions.

Both structures are free to view from outside. Only Senjokaku requires the ¥100 admission to enter.

Views from the Hilltop

Senjokaku sits on a hillside above Itsukushima Shrine, which means it offers elevated views that you cannot get from the shrine itself. From the pavilion's open sides, you can look down on:

• The floating torii gate — visible across the water during high tide, or standing on exposed mudflats during low tide
• Itsukushima Shrine and its vermillion corridors from above
• The island's forested mountains rising behind the shrine complex
• The Seto Inland Sea and the mainland coast in the distance

The views change significantly with the tide. During high tide, the torii gate appears to float on the water — the classic Miyajima image. During low tide, the gate stands on exposed ground, which offers a different perspective and allows you to see the scale of the gate's supporting structure.

Many visitors recommend visiting Senjokaku in the afternoon, when the light on the torii gate and shrine below is particularly warm.

Practical Information

Hours, Admission, and Access

According to the Toyokuni Shrine official site:

Detail	Information
Hours	8:30 AM - 4:30 PM (last entry 4:00 PM)
Admission	¥100 (~$0.70) adults, ¥50 (~$0.35) children

The five-story pagoda is free to view from outside at any time. Its interior is not open to the public.

Getting there from Hiroshima: Take the JR Sanyo Line from Hiroshima Station to Miyajimaguchi Station (approximately 30 minutes), then the ferry to Miyajima Island (approximately 10 minutes). From the ferry terminal, walk through the shopping street and past Itsukushima Shrine, then climb the stone steps up the hill — total walking time is approximately 15-20 minutes. Wear comfortable shoes for the uphill climb.

Best Time to Visit

Senjokaku is pleasant year-round, but certain seasons add specific appeal:

• Autumn (October-November): Autumn foliage surrounds the hall, and the contrast between red maple leaves and the weathered wooden structure is striking.
• Spring (March-April): Cherry blossoms frame the pagoda and hall.
• Summer: The open-air design provides natural cooling. The breezy pavilion is one of the most comfortable spots on the island during hot weather.
• Winter: Quieter crowds, but the open structure offers no protection from cold.

Early morning or late afternoon visits offer the best light for photography and smaller crowds. Most tour groups focus on Itsukushima Shrine and the shopping street, leaving Senjokaku relatively uncrowded even during peak seasons.
