Was the image model of apparel brand "RYBC" for the 2019 spring&summer season along with fellow 9bic member Kunugi Minato
Appeared in the stage play "Smartphone Dad" (Smartphone Oyaji) as Kimoto Kousuke (starring role/main cast)
Ryoga says of himself that he is a bit on the crazy side. He is fun loving and adventurous and can be quite mischievous as well.
At events Ryoga is very open and active when it comes to interacting with fans. He tries to communicate with people regardless of language barriers and makes sure fans have a good time. He is very easy to talk to and does not shy away from physical contact.
Ryoga is considered the "center" of 9bic as he was given the image colour red. This is most likely due to his good looks and his singing and dancing abilities, making him an all-rounder in terms of "idol must have" abilities. Despite that, he is not the 'leader' of the group (that position seems to b Keiichirou's). He says of himself that he has some loose screws and is a bit on the crazy side. He also has moments of stupidity sometimes.
Just like his fellow group mate Ichikawa Keiichirou, Ryoga was active in the entertainment/modelling business before joining 9bic. He came to Tokyo for events and met Yonemura Kaito there, who then invited him to join 9bic, which he did.
Ryoga shares a room with Minato at the 9bic House.
It's known that Ryoga has at least one older brother. He said they look alike.
Ryoga usually speaks in "proper" Japanese in the YouTube videos and at events but he uses his local home dialect on Twitter sometimes.
Ryoga has an extremely hard time waking up in the mornings. He is not a morning person.
Ryoga also hates mayonnaise.
Ryoga used to have slightly crooked canines ('yaiba' or 'fangs' in Japanese) but he had his teeth fixed, so now they're gone.
