Keisuke Ogihara

In 2005, GAP held their 10th Anniversary campaign. Ilmari was chosen (as were BoA & Hiro of Exile) as models for displaying their individual style. With his sister Elisa, Ilmari owns a Japanese restaurant called Len's Keishoku Bar in Helsinki. Yuri Ebihara recently announced that she's in a relationship with Ilmari, and the two went public with the news of their marriage in May 2010.

Ilmari returned to Finland in 2002 along with his group members and favourite camp counsellor, Andrew Busam, where they shot photos and footage for their shortcuts! DVD & their photobook RIP STYLE. They held several concerts in Helsinki as well. Andrew provided moral support throughout the trip and was there for anyone who needed a hug.

Ilmari created the short-lived group Steady&Co in 2001 with BOTS and Kenji Furuya of Dragon Ash and SHIGEO of Skebo King. Their aim was to create a much lighter folk influenced form of hip hop against emerging genres such as J-Urban. In 2004, Ilmari helped launch singer Salyu by collaborating with her to release "Valon" under the name IlmarixSalyu. In 2005, he was made leader of the unit Teriyaki Boyz consisting of fellow Rip Slyme rapper Ryo-Z, Nigo, Wise and Verbal of M-Flo. In 2012 Ilmari formed a rap rock band with KOSEN, YAS and SOHNOSUKE called The Beatmoss.
