The Tachibanazuka Kofun is located in a corner of the schoolyard of Miyako Town Kuroda Elementary School, about 500 meters east of
Ayazuka Kofun. It is a tomb made of gigantic
granite megaliths. Since it has been open for a long time, no
grave goods have been discovered. It was previously thought to be an -style circular tumulus, but research from 1995 revealed that it was actually a -style square tumulus, measuring 37 meters from north-to-south and 52 meters from east-to-west with a height of 3.8 meters. The structure of the stone
burial chamber is very similar to that of the nearby Ayazuka Kofun. From the structure of the burial chamber, it is believed to be slightly older than the Ayazuka Kofun, and was built around the end of the 6th century. It is located in a corner of Kuroda Elementary School's schoolyard, near
Japan National Route 201 and approximately 4.6 kilometers due west of
Imagawa-Kappa Station on the
Heisei Chikuhō Railway Tagawa Line. ==See also==
