In 1885,
my great-grandfather who is the founder started Seiryu-do and I am the fourth generation.

It newly started Seiryu-do in Hiroo through the stage of Ginza and Kamakura.
I would like to introduce the profound fascination of artist and their works,

which is mainly Japanese and oil paintings in the 1900s to you.

Our mission is to connect precious works of art with people’s life stories 

and pass on the beautiful stories to the next generation.
