Bansuiso is a Renaissance-style villa built as a second home of Earl Sadakoto Hisamatsu, a descendant of the former Matsuyama clan. It has hosted the Imperial Family and been a popular venue for high society notables of various artistic fields. Making a good use of the gorgeous architecture of the time, it continues to host a range of events and exhibitions today. Although located in the city centre, the villa allows visitors to relax in the charming retro rooms isolated from the hustle and bustle going on outside.
