It's a kofun whose front section remains, more or less, in a shape like a taproot. There aren't many places where you can photograph the round rear section, but you can get fairly nice shots through the mesh of the fence at the adjacent Kansai Electric Power substation. That said, it looks like a round kofun.

Chinooka Kofun (ちのおかこふん) A kofun surrounded by a tall fence along a narrow road in a residential area. Near the top of the kofun, I could see something that looked like a gorinto stupa. You can't get close to it. It's said to be the oldest in Sakai City. Plate-shaped?

Chinooka Kofun (ちのおかこふん) Originally a keyhole-shaped kofun with a mound length of 150 m, estimated to have been built in the late 4th century. Most of the front section has been lost. It's on the southwest side of the Mozu Kofun Group, and at the time it was built, Osaka Bay probably came right up close to it. Since it's in the middle of a residential area, it's hard to get a sense of the whole thing, but the view from the south side of the kofun is relatively easy to see. The explanation board and stone monument are also at the southern edge. According to the explanation board, "Judging from the shape of the stone coffin and the artifacts, Chinooka Kofun is thought to have been built around the late 4th century, and was the first large keyhole-shaped kofun built in the Mozu Kofun Group." (￣o￣)／ When the center of kofun building moved from inland Yamato to Mozu and Kawachi, the first place the ancient people chose was this spot, clearly visible from the sea... I feel like I can somehow understand how the ancient people felt.

It's a keyhole-shaped kofun, but the front section has been destroyed. At first glance, people tend to think the Kansai Electric Power-related site is that part, but as stated on the information board, it's actually the residential area to the southwest. In aerial photos from the early Showa era, the keyhole shape was mostly intact, but in wartime aerial photos the front section had been leveled, making it look like an ordinary round kofun, and around 1960 the west side of the round part was also slightly cut away by development, leaving it as it is today.

It's near a main road, but the front section, whose shape is no longer intact, seems to be the spot where you can see the kofun. It's surrounded by residential areas and company property. The road leading to it isn't wide, so parking is difficult. It's the oldest kofun in the Mozu Kofun Group and I found it interesting, but the shape of the mound was just too... it was a shock.
