| Izumi Hall was planned and constructed
as part of the 60th anniversary project of Sumitomo

In pursuit of creating an ideal sound field, the Hall
was modeled after the “Grosser Musikvereinssaal (Musikverein
Main Hall) in Vienna”, home of the Vienna Philharmonic.
It is a shoebox style concert hall with 821 seats.
With acoustics, elaborately considered not only through
the design of the ceiling and walls but also the floor,
chairs, and 8 chandeliers, a space filled with a confluence
of instruments has been realized.
The reverberation time is between 1.8 and 2 seconds,
which is regarded as the best time for classical chamber

With Tadashi Isoyama (Professor of Kunitachi College
of Music) as the musical director, Izumi Hall sponsors
about 30 original performances each year.
