Otsukahara Kofun is a grassy keyhole-shaped burial mound set in rural Asahi. Photograph low-profile earthworks, surrounding paddy fields and seasonal foliage; golden hour emphasizes the mound’s silhouette. Small site with limited facilities—access by car, roadside parking; respect signs and avoid disturbing graves. Visit spring/autumn for color, early morning weekdays for solitude and soft light.
