Kosanji Temple, Onomichi

Kosanji Temple stands on Ikuchijima Island in the Seto Inland Sea, part of Hiroshima Prefecture's Onomichi city. Built between 1936 and 1977, this relatively modern temple was constructed by businessman Kozo Kosanji as a monument to his mother. What makes this temple extraordinary is not its religious heritage but rather its ambitious architectural vision—Kosanji spent over 40 years and his entire fortune recreating famous structures from across Japan, resulting in a complex that some call the "Nikkō of the West."

The temple grounds showcase 15 buildings that replicate or draw inspiration from Japan's most celebrated historical architecture. The main hall replicates Nikkō Tōshō-gū's Yomeimon Gate, while other structures reference the Phoenix Hall of Byōdō-in and elements from various National Treasures. Beyond traditional architecture, the site features the Hill of Hope, an outdoor marble sculpture garden covering 5,000 square meters with works inspired by classical and Renaissance art. The juxtaposition of Buddhist temple architecture with Western sculptural traditions creates an unusual and visually striking environment.

Visitors can explore the temple buildings, walk through carefully landscaped gardens, and view the extensive art collection housed within the complex. The Treasure House contains artifacts and artworks collected by Kosanji. The marble garden offers panoramic views of the Seto Inland Sea and neighboring islands. While some architectural purists debate the temple's authenticity, the site undeniably represents one individual's extraordinary dedication and artistic vision.

Ikuchijima Island connects to the mainland via the Ikuchi Bridge, part of the Shimanami Kaido cycling route. From Onomichi, take a bus to Setoda Port, then walk approximately 15 minutes to the temple. Alternatively, cyclists following the Shimanami Kaido can easily access the temple from the route. Visitors arriving by car will find parking available near the entrance. Admission costs ¥1,400 for adults, which includes entry to both the temple grounds and the Treasure House.
