July 2020. The tour was cancelled, however, due to the COVID-19 pandemic, and a planned Japan tour was postponed. On 22 and 23 November 2020, Radwimps held a special fifteenth anniversary concert at Yokohama Arena. In September 2021, Akira Kuwahara announced that he would go on hiatus for an indefinite period of time, after the weekly magazine Shūkan Bunshun reported his extramarital affair with a former model. In 2022, Radwimps provided music for the film The Last Ten Years, released on 4 March. The same year, the band also wrote music for Shinkai's film Suzume, making this the third time they collaborated with the director. In October, Kuwahara returned to the band after his year-long hiatus. Side projects Radwimps have also released music under the moniker Misoshiru's ("The Miso-Soups"), beginning with the song "Jennifer Yamada-san" from the 2006 single "Yūshinron". A band with a primarily punk rock sound who perform disguised in Groucho glasses and red T-shirts, Misoshiru's released their debut album, Me So She Loose, in March 2013. In 2008, Yojiro Noda acted as a record producer for the first time, writing and producing the song "Labrador" for singer Chara, which was used as the leading promotional track for her album Honey. During the recording sessions, Noda collaborated with musicians such as Nobuaki Kaneko (Rize), Yoshifumi Naoi (Bump of Chicken), Susumu Nishikawa (Diamond Head), and Koichi Tsutaya. In 2010, Radwimps took part in a special project called Terrakoya, a commemorative band formed for the EMI Rocks 50th anniversary of EMI Music Japan rock concert, featuring Radwimps along with Acidman, Fujifabric, Atsushi Horie (Straightener), Susumu Nishikawa, The Telephones, and Kazuya Yoshii. The band released the song "Emi" in November, written by Noda in collaboration with Yoshii. Yojiro Noda made his solo debut under the name Illion in 2013 and released his debut album, Ubu, on 25 February 2013, in the United Kingdom. Songwriting Lead vocalist Yojiro Noda writes all of the band's music and lyrics (the only exception currently is the bonus track "Yonaki" from Radwimps 4, written by Akira Kuwahara). Almost all of Noda's lyrics are based on events he has experienced, or nonfictional events. "Enren" from Radwimps 4: Okazu no Gohan, released in 2006, was the first fictional-themed song Noda wrote since the band formed.
