- Died: 1576
- Sons: Takanashi Masayori

Sumiyori was the son of Takanashi Masamori. He held Nakano castle in Shinano and became involved, alongside the Murakami, in a protracted conflict with the Takeda family of Kai. Around 1553 Sumiyori, Murakami Yoshikiyo, and others appealed to Uesugi Kenshin of Echigo to reclaim their lands, which had at this point been lost to the Takeda. Sumiyori went on to serve under Kenshin's banner in the hopes that he might be restored to his old domain, but this was not to be.
