The four released a video thanking fans and followers alike for helping the channel reach the number.
By comparison, King & Prince's channel, centered mostly in music videos, ranked second with 6.2 million views and 670 000 subscribers.
Jyanino Channel was ranked fourth for their video in which Yamada was revealed as the last member, and first as "Top creators with increasing number of subscribers in Japan".

Ninomiya responded: "When (the manga) comes out, let's have a toast with Clear Asahi,"[27] The four filmed and photographed different moments behind the scenes both at the commercial taping and at the press conference, which were included in a video in the channel.

On October 4, 2023, Jyanino Channel announced a name change and a small activity suspension period.

On August 7, 2024, Bunshun Online reported about a secret meeting between Nakamaru, who is married, and a young woman in a Tokyo hotel.
At the beginning, there was an obvious sense of distance, as the members didn't know much about the others, other than their musical side, but soon the group became so close that even the "taboo actions" (such not calling a senior with -kun or -san) were thrown out the window.
