May 2016, the Omiya Bonsai Art Museum is closed on:
From March - October,
the museum is open until 16:30 (entrance before 16:00).
On Thursdays, gardens in the Omiya Bonsai Village are closed, too.
This year Children's Day falls on Thursday and the
museum is open on May 5.
Gardens of the Omiya Bonsai Village will be open on May 5, too,
because it is during the Grand Bonsai Festival period.
