Arena to celebrate his 50th birthday. Former Boøwy drummer Makoto Takahashi appeared as a special guest and together they played Boøwy's "Justy" and "No. New York". Hotei made his directorial debut in April 2012, with the stage play Psychedelic Pain, for which he also wrote the music. On May 8, it was announced that Hotei would move to London in June, in hopes of starting an international career. Relocating to London and international focus 2012–2014 After years of spending a great deal of time in the UK, Hotei and his family relocated fully to London in June 2012, primarily for Hotei to pursue his dream of an international career. Hotei played his first major show in the UK in December 2012 at The Roundhouse in London. In November 2013 Hotei played 2 headline shows, first at Shepherd's Bush Empire in London, and then at the Highline Ballroom in New York. In an interview with the Financial Times, Hotei commented, "Last year I turned 50...time goes quickly, it's my last chance to try and get my dream. I want to play all over the world." On March 6, 2014, Hotei joined The Rolling Stones on stage during the final show of their tour in Japan. He was a surprise guest at their Tokyo Dome concert, playing the song "Respectable" before a crowd of 53,000 fans. Hotei's most famous song "Battle Without Honor or Humanity" was selected for a nationwide TV commercial in the UK for Buxton Water's "Naturally Pumped Up" campaign. The campaign launched in June 2014, with plans to run for six months. Joined by band members Zachary Alford (drums), Tony Grey (bass), and Toshiyuki Kishi (keyboard/programming), Hotei played a series of private shows and summer festivals during June, July, and August 2014. This included appearances at England's Cornbury Festival, Switzerland's Montreux Jazz Festival, and the UK's Y Not Festival. An earlier warmup gig was held at The Lexington in London, and Hotei was also invited to perform solo as a special guest of Lord March during the Goodwood Festival of Speed. Live4Ever covered the Y Not Festival, describing Hotei as "undoubtedly the coolest man on site during his afternoon set on the main stage, performing instrumental sections fit for several people in his ability to flick between technically staggering solos and crunching guitar chords whilst jumping around the stage like an excitable Duracell rabbit."
