History

Founded in April 2012

Office Zero began as a voluntary organisation led by keyboardist Hiroshi Yokoyama, producing self-initiated performances of classical, early, and contemporary music.

2015–2019
The group consistently presented small-scale chamber music concerts and solo recitals for keyboard instruments. Programmes focused on early music performed on the harpsichord and 20th-century works for piano, introducing these repertoires to wider audiences.

Educational events in the form of lecture-recitals were also held in public facilities and galleries, integrating performance with commentary.

2020 (COVID-19 Pandemic)
Due to the spread of the coronavirus, live activities were temporarily suspended. Instead, an online salon was launched, offering seminars on Baroque music and historically informed performance practices.

2024
The “Arts in Everyday” project was conceived, aiming to explore experimental and conceptual works within a classical concert framework.

2025
May: The inaugural performance of Arts in Everyday 2025 — John Cage and Yoko Ono was held at Hillside Plaza, located within Hillside Terrace in Daikanyama, Tokyo.
