[Sasarindo] Ryukoku Mon / Why was the misconception that the crest of Seiwa-Genji was Ryukoku? Tsuneuji HOSHINO argues that since all the clans of Murakami-Genji used sasarayutondo, they were mistakenly regarded as the family crest of Seiwa-Genji. This would be a valid interpretation. In addition to Murakami-Genji, Uda-Genji (Minamoto clan) was used for Ryugo-mon. According to "Unjo Meiran," the Murakami-Genji (Minamoto clan) were descended from nine families: Koga, Rokujo, Iwakura, Chigusa, Baikei, Atago, Kuze, Higashikuze, and Uematsu. The Uda-Genji had five families, Niwata, Ayanokoji, Itsutsuji, Ohara and Jiko-ji Temple, and both used Ryukoku-mon . Therefore, it was called the Murakami-Genji and the Uda-Genji, both of which used the Ryukoku-mon crest, so it is assumed that the Seiwa-Genji was also the Ryukoku-mon crest, and the misunderstanding was born. According to reliable records, the fact that Seiwa-Genji used the Ryuto as its Jomon is nowhere to be found... It is clear that Ryuto was not a typical Kamon of Seiwa-Genji. ('Japanese Heraldry')
