This is a glass bowl with the tokusa “horsetail” pattern from the Taisho Roman glass series by Hirota Glass, a long-established glass manufacturer in Tokyo.

The tokusa motif, cherished since the Edo period (1603 CE–1868 CE), symbolizes growth and prosperity. Its straight, upward-reaching lines embody aspirations for success and flourishing, making it a beloved design through the ages.

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.

Hirota Glass, founded in 1899, is one of Tokyo's oldest glass makers. It combines traditional Japanese glassblowing and Edo Kiriko techniques with modern home decor designs, producing harmonious and timeless products.
