About Kōji Tamaki
Kōji Tamaki is a Japanese singer-songwriter and actor. He has been well known as frontman of the rock band Anzen Chitai that debuted in 1982 and enjoyed a successful career, particularly during the 1980s. In the 1990s, he also began his career as a solo artist. He is widely regarded as one of the greatest Japanese vocalists. On his 2012 album Offer Music Box, Tamaki — who composed the original song — covered Yuki Saito's song "Kanashimi yo Konnichi wa", which was used as the first theme song for the anime television series Maison Ikkoku. In 1987, Tamaki released his first solo single "All I Do" and continued his solo career after Anzen Chitai went into hiatus (1993–2001, 2004–2009). In 2014, he was ranked first by a panel of 200 experts for the best ever singing voice in Japan.
