IimoriIwa
"This rock formation is located east of the Ichimai-iwa Monolith, one of the most famous sights along the Kozagawa Dike, a 22-kilometer-long stretch of the 56-kilometer-long Kozagawa River which was formed via ancient volcanic activity. The formation can just be seen amidst the mountains from the Tachiai Bridge along National Route 371. Its name literally means ""Rice Mound Rock"" and is derived from its resemblance to a heaping mound of cooked rice. Be sure to check it out along with the numerous other sightseeing destinations along the Kozagawa River."
