In 2008, Hirayanagi made his Ring of Honor debut in the opening match of the 14 September ROH: The Tokyo Summit show. Teaming with Kotaro Suzuki, he lost to the NJPW duo of No Limit (Tetsuya Naito and Yujiro Takahashi). Later that year he gained his first trophy when he teamed with Yoshinobu Kanemaru and Kotaro Suzuki to defeat KENTA, Taiji Ishimori and Ippei Ota to win that year's One Day Junior Heavyweight Six Man Tag Tournament in Sapporo, Hokkaido.
