About
Set in Tokyo, a city where music is woven into the fabric of daily life, impromptu stages line the major stations where anyone can perform. In an era where a viral SNS post can make you a star overnight, instrument shops have become trendy youth spots with built-in cafes. The band boom has spread globally, merging unique musical cultures from every nation. For instance, Japanese bands are known for meticulous technical skill, Western bands for energetic performances, and Southeast Asian bands for a trending new genre incorporating folk instruments. Talents from all over the world gather in the musical hub of TOKYO.
