The deities enshrined at Kyoto Ryozen Gokoku-jinja Shrine include Ryoma SAKAMOTO who was assassinated in Kyoto, with a bronze statue of him standing at the shrine and the Ryoma-sai Festival held on the anniversary of both his birth and death on November 15 of each year to honor his memory and comfort his soul (his birth and death originally took place on November 15 of the old calendar but the festival is held on November 15 of the Gregorian calendar).
祭神の中には京都で暗殺された坂本龍馬も含まれており、境内に銅像が作られているほか、誕生日であり命日でもある11月15日には、龍馬の遺徳を偲び霊を慰める龍馬祭が行われる（誕生日・命日は本来は旧暦11月15日だが、祭は新暦11月15日に行われる）。
