He would later leave D-topia and join Tsubasa Records as a music producer. As part of Tsubasa, he was given the responsibility of managing and producing various acts, including Pour Lui and later, BiS. He was later added to SCRAMBLES, formed by frequent partner, Matsukuma Kenta.
In early 2013, Watanabe co-founded the band, this is not a business. He initially acted as their vocalist (the "first-generation Kato Kouban") until sometime after the release of their first digital single, WITH A MISSION, after which another vocalist took over the role.
After BiS disbanded in 2014, he left Tsubasa Records to form his own company, WACK.
In July 2015, following the departure of Kato Kouban, Watanabe took over as vocalist for This is not a business, claiming that he was actually the original Kato, and that the previous was merely the "second generation". He remained the vocalist of the band until the third-generation Kato Kouban joined on September 7th.
In April 2016, a biography about Watanabe and his work in the idol industry, Watanabe Junnosuke: Idol o Create Suru, was published.
Watanabe's fashion brand NEGLECT ADULT PATiENTS was launched in 2018, with the philosophy "ANTi ADULT". The brand is sold in WACK's MULTiPLE MANiACS store, which frequently holds pop-up events for various WACK activities and housed KiKA'S bar.
As of 2021, Watanabe's profile has been removed from SCRAMBLES' website, indicating that he may have left. Despite this, he still continues to closely work with them.
Although he attended one of the top secondary schools in Japan, he stopped attending school during his second year of junior high and dropped out entirely during high school.
He studied Political Economics at Waseda University.
His first time going abroad on vacation was in December 2019, when he visited the United Kingdom and Europe.
In late October, the tabloid Shukan Bunshun reported that Watanabe was having an affair with ZOC and former ANGERME member, Kannagi Maro. Both Watanabe and ZOC later confirmed the relationship and stated that Watanabe was long-separated from his wife and in the middle of divorce proceedings. As the reports came out in the lead-up to multiple collaborations with BiS and ZOC, it is debated by fans to this day whether the relationship was legitimate or staged.
