This is a single flower vase from the Taisho Roman glass series by Hirota Glass, a long-established glass manufacturer in Tokyo.

This vase has a cute round body like a water balloon. The height is low, but the body is surprisingly large and stable.

The checkered pattern, traditionally called "Ichimatsu," conveys a nostalgic atmosphere. The pattern is also applied to the narrow part of the mouth.

This pattern is created not by painting or pigments, but by the "Aburidashi (invisible ink) technique," which uses specially blended glass materials to create an opalescent, milky-white pattern by the sudden temperature difference when molten glass comes into contact with a mold with a precisely engraved pattern.

The single-flower vases are packaged in a decorative box, making them ideal for gift-giving. 

Hirota Glass is one of the oldest glass makers in Tokyo, founded in 1899. Based on the data of designs handed down to the company since its foundation, Hirota Glass has continued to produce a series of products that harmonize with contemporary home décor, while inheriting the traditional techniques of Japanese glassblowing and Edo Kiriko.
