Ryōgoku Kajinosuke II (両國 勇治郎, March 18, 1892 – August 10, 1960) was a Japanese sumo wrestler.

He reached the top makuuchi division in May 1914 and won the championship with a 9-0-1 record.

He reached sekiwake rank in January 1915 but was unable to climb any higher and spent most of the rest of his career as a maegashira.

After retirement, he worked under the name Takekuma in the Dewanoumi ichimon, and recruited Musashiyama.
