Q.Asuka's tombs: how do Ishibutai, Takamatsuzuka and Kitora differ?
Published 2026-06-18
Answer
Asuka's famous tombs differ sharply in character. Ishibutai is one of Japan's largest square tombs, its giant stones exposed (said to be Soga no Umako's grave); Takamatsuzuka and Kitora are late-period tombs famous for vivid murals, both designated National Treasures. Tombs of imperial rank, meanwhile, take a special octagonal form.
Ishibutai — exposed megaliths, one of Japan's largest square tombs
Ishibutai is one of Japan's largest square tombs, its horizontal stone chamber laid bare after the covering mound was lost. Its 30-odd stones weigh roughly 2,300 tons in total. The occupant is said to be Soga no Umako, a powerful figure of the Asuka period. Famed for the sheer scale of its exposed megaliths, it is one of Asuka's signature sights.

Takamatsuzuka & Kitora — late-period tombs with vivid murals
Takamatsuzuka and Kitora are both late-period tombs from the late 7th to early 8th century. Takamatsuzuka's vivid murals were found in 1972; its group of female figures, nicknamed the "Asuka Beauties," was designated a National Treasure in 1974. Kitora bears the four guardian gods, the zodiac, a star chart and sun/moon, with five mural surfaces designated National Treasures in 2019. Kitora's star chart is the world's oldest surviving formal Chinese-style star map, and Kitora is the only tomb where all four guardian gods survive (Takamatsuzuka lost its Suzaku to looting).
| Takamatsuzuka | Kitora | |
|---|---|---|
| National Treasure | 1974 | 2019 |
| Signature murals | 'Asuka Beauties' (female figures) | Four gods, zodiac, star chart |
| Four guardian gods | Suzaku lost (looting) | All four survive |
Imperial tombs are octagonal — rank shown through shape
In the late Asuka period, the tombs of emperors (great kings) took a special octagonal form. In Asuka, the joint tomb of Emperor Tenmu and Empress Jitō, Nakaoyama Kofun (thought to be Emperor Monmu's tomb) and Kengoshizuka Kofun (possibly Empress Saimei's tomb) are octagonal. The octagon, linked to Chinese ideas of the Son of Heaven, is thought to express imperial rank through shape itself.
