The Takamatsuzuka Tomb (高松塚古墳 Takamatsuzuka Kofun?) or "Tall Pine Tree Ancient Burial Mound" in Japanese is an ancient circular tomb in Asuka village, Nara Prefecture, Japan.
The tomb is thought to have been built at some time between the end of the 7th century and the beginning of the 8th century. It was accidentally discovered by a local farmer in the 1960s.
The mound of the tomb was built of alternating layers of clay and sand. It is about 16 meters in diameter and 5 meters high. Excavation yielded a burial chamber with painted fresco wall paintings of courtiers in Goguryeo-style garb. The paintings are in full color with red, blue, gold, and silver foil representing four male followers and four abigails together with the Azure Dragon, Black Tortoise, White Tiger, and Vermilion Bird groups of stars. The paintings are designated a National Treasure.
For whom the tomb was built is unknown, but the decorations suggest it is for a member of the Japanese royal family or a high-ranking nobleman. Candidates include:
