【Designated by the City：Historic Site】Tomb of the Master of Yusuma

Presently in Karimata, there are four tombs known as the Yusumanushu-nu Haka. This tomb is one of them, and is located at the top of the hill which commands a view over the four areas of Shimajiri, Ogami, Karimata, and Ikema. The structural features resemble that of the Tsuga-baka tombs, with double walls made of piled stones surrounding it. There is a single slab of rock making the arched gate facing south-southwest. The tomb has a single inner chamber with two openings. It is said that this tomb has been used up to the modern day by generations of the decendants of the Yusumanushu-nu Haka.
Yusumanushu is a reference used for the chief that controlled the villages of Karimata, Shimajiri, Ogami, and Ikema, and it is written in the history book Yoseikyuki, “Long ago, a man by the childhood name of Mumusamui from Karimata, came to rule the four villages of Karimata, Shimajiri, Ogami, and Ikema.” We can see from the poetry written in the “Yusumanushu-nu Ayakgu,” that the Yusumanushu himself was also an excellent writer.
The Yusumanushu was under the rule of Nakasone Tuyumya and ruled with benevolence. It is told that during his rule, he built the Watanji-Bashi Bridge, connecting Karimat and Shimajiri, improved farm roads, set rest areas between Karimata and Hirara, and worked to dig water wells.
