Slow LIVEFri 9/5 – Sun 9/7, Tokyo

Slow LIVE is an open-air festival held at Ikegami Honmon-ji, a temple in Tokyo with over 700 years of history. Embracing the principles of Slow Food in music as well, the event is guided by the concept of “let’s enjoy music slowly.” On the day, there is a single-stage setup with seating, and more changeover time than at typical festivals, so you can take your time not only with the live performances but also with food and more.
