The Tomori Meryozan Kofun (Emperor Ojin Mausoleum) is a massive keyhole-shaped burial mound located in Habikino City, Osaka Prefecture. Estimated to have been constructed in the first half of the 5th century, it is a prominent part of the Furuichi Kofun Group. The mound features a length of approximately 425 meters, a height of about 36 meters at the rear circular part, and a total volume of roughly 1.43 million cubic meters. This site serves as a monumental testament to the advanced engineering skills and social structures of ancient Japan. Surrounded by lush greenery, the area offers a serene and contemplative atmosphere.
According to long-standing tradition, this mound is believed to be the resting place of Emperor Ojin. Archaeological studies, including the analysis of cylindrical haniwa (terracotta funerary objects) and Sue ware pottery, suggest the tomb was constructed during the first quarter of the 5th century. While academic debates continue regarding the exact identity of the person interred here, the site has long been a cornerstone of Japanese ancient history. Furthermore, the nearby Hota Hachiman Shrine, which developed in close connection to the presence of this mausoleum, highlights the deep-rooted historical and religious ties of the region.
The distinctive keyhole shape (zenpokoen-fun) is the most striking feature of the mound. The vast scale and the way the structure integrates with the natural topography demonstrate the sophisticated construction techniques of the era. Visitors can observe the historical context of the surrounding landscape, which includes facilities that help explain the ancient scenery. The adjacent Hota Hachiman Shrine also holds significant historical value, with connections to historical documents like the 'Hota So-byo Engi Emaki' from the Muromachi period, enriching the cultural narrative of the area.
While the site is accessible year-round, we recommend visiting during daylight hours to fully appreciate the scale of the mound. The surrounding vegetation changes beautifully with the seasons; during the lush green seasons, the natural landscape surrounding the mound is particularly striking. On clear days, the distinct shape of the keyhole mound is easily visible, making it an ideal time for photography and historical observation.
Visitors can explore the intersection of nature and ancient history by walking around the perimeter of the mound. It is a wonderful way to experience the physical scale of Japan's funerary culture. To gain a deeper understanding of how ancient beliefs evolved into modern-day traditions, we highly recommend visiting the nearby Hota Hachiman Shrine in conjunction with the kofun.
To the south of the mound lies the Hota Hachiman Shrine, a vital center of local faith that grew alongside the history of Emperor Ojin's tomb. The area is also part of a larger historical landscape that includes other significant tombs within the Furuichi Kofun Group and the nearby Daisenryo Kofun (Emperor Nintoku's Tomb), both of which are part of the UNESCO World Heritage list.
