山下亨是日本摇滚乐团ONE OK ROCK的唯一吉他手，多半以艺名Toru称之。

成立ONE OK ROCK前，曾和小浜良太（现ONE OK ROCK的贝斯手Ryota）在Hip-Hop团体HEADS内活动，两人为童年好友。他们两人于2005年就读堀越高等学校时和学长Alex成立了ONE OK ROCK，担任团长、第二吉他手以及主唱。并在听到森内贵宽（现ONE OK ROCK的主唱Taka）的演唱时，力邀他加入ONE OK ROCK担任主唱。和Taka为乐团的主要词曲创作者。2009年Alex因个人因素离开乐团后，担任乐团的第一吉他手，并将已有歌曲重新编曲为单吉他的形式。

TORU (rus. Телеоператорный Режим Управления - Teleoperated Mode of (spacecraft) Control ) system is a manual docking system of Russian Soyuz and Progress spacecraft that serves as a backup to the automatic Kurs system. It was used on the former Mir and Salyut space stations and is currently in use on the International Space Station. The TORU system became known to the public in 1997 when it was used during the manual approach of Progress M-34 to Mir that ended up with a dangerous collision. It was an approach of a previously used Progress spacecraft with the purpose of research work on further improvement of TORU.
