This is a glass bowl with a sakura “cherry blossom” design from the Taisho Roman glass series by Hirota Glass, a long-established glass manufacturer in Tokyo.

Cherry blossoms, with their charming appearance and deep cultural significance, are beloved not only in Japan but also around the world. They symbolize both natural beauty and rich tradition.

This pattern is created by the aburidashi "invisible ink" technique, which uses specially blended glass materials to form an opalescent, milky-white design. The patterns emerge due to the sudden change in temperature when the molten glass comes into contact with a precisely engraved mold.
