Kotohiki Hachimangū (琴弾八幡宮)

Kotohiki Hachimangū sits on Mount Kotohiki above the Seto Inland Sea, where its most famous feature is not architecture but a sand drawing: the character 銭 (zeni, meaning “coin”) raked into the white beach below, measuring 122 meters east to west and 90 meters north to south. This enormous sand symbol — visible only from the observation deck of the shrine or from the air — is remade twice annually by volunteers who rake it back into existence after wind and tide have blurred its edges. The practice began in the Edo period as a prayer for prosperity, and continues unchanged. To stand above it is to see a massive meditation on money written in white sand against dark pine.

The shrine was founded in 703 CE when Emperor Monmu ordered its construction after Empress Jingū was said to have stopped at this beach during her legendary campaign in Korea. The location was chosen because the mountain’s shape resembled a koto (Japanese harp), and when wind passed through the pines, the sound echoed like plucked strings — hence the name Kotohiki, “harp-playing.” The shrine became a major pilgrimage site on the Shikoku 88 Temple circuit despite being a Shinto shrine, positioned between temples 68 and 69. The zeni-gata sand drawing was first created in 1633 during the Kan’ei era, commissioned by the local lord Ikoma Takatoshi to symbolize the circulation of wealth and the importance of commerce to the domain.

Emperor Ōjin (Hondawake no Mikoto) is the primary deity, worshipped here in his deified form as Hachiman, the god of warriors and protectors of Japan. He is enshrined alongside his mother Empress Jingū and the Sumiyoshi Sanjin (three gods of the sea). Hachiman’s association with this location stems from the Jingū legend and the shrine’s position overlooking maritime trade routes through the Seto Inland Sea. The combination of military protection and ocean safety made Kotohiki a shrine for sailors, merchants, and warriors throughout the medieval period. The messenger here is the dove, common to all Hachiman shrines, representing peace achieved through strength.

The founding legend tells that when Empress Jingū returned from her conquest of the Korean kingdoms (a mythological campaign recorded in the Nihon Shoki), her fleet stopped at this beach. She was pregnant with the future Emperor Ōjin, who would later be deified as Hachiman. As she rested, she heard the sound of a koto playing from the mountain, though no musicians were present. Taking this as a divine sign, she ordered a shrine built there. The zeni-gata sand symbol has its own origin story: in the early Edo period, a white-robed monk appeared before Ikoma Takatoshi in a dream and drew the character for “coin” in sand, saying “prosperity flows like water when money circulates freely.” When the lord woke, he commissioned the enormous sand drawing as a permanent prayer for economic vitality, believing it would draw wealth to Kan’onji and the entire region.

The shrine complex consists of the main hall (honden) built in the Hachiman-zukuri style, painted in vermilion and white, positioned to overlook both the zeni-gata below and the Seto Inland Sea beyond. Stone steps climb through dense pine forest from the beach to the shrine grounds. The observation deck (Zenigata Suna-e Viewing Platform) extends from the mountainside specifically to view the sand drawing from above — the only angle from which its character is legible. The beach itself, Ariake Beach, is part of Setonaikai National Park. The sand used is white quartz, chosen for contrast and durability. Within the shrine grounds stands a secondary shrine dedicated to Kotohiki Daimyōjin, the local mountain deity believed to create the harp-like sounds through the pines.

• Zenigata Sand Drawing Restoration (Spring and Autumn) — Volunteers rake the 4,000-ton sand character back into shape using traditional wooden rakes, a process taking several days and requiring precise measurement from the observation platform above
• Chigogyo Procession (October) — Children dressed as sacred attendants are carried through the town during the annual autumn festival, recreating Empress Jingū’s imperial procession
• Hatsumode (January 1-3) — Visitors climb the mountain at dawn to make first prayers for financial prosperity in the new year while viewing the sunrise over the Inland Sea

Late afternoon in autumn, when the angle of light sharpens the contrast between white sand and dark water, making the zeni-gata most photographically dramatic. Visit during the spring or autumn restoration period (usually late March and late September) to witness the sand raking ritual. Avoid midday in summer — the exposed observation deck becomes extremely hot, and haze reduces visibility of the sand drawing. The pine-covered approach is coolest in early morning.
