Hanashyo was founded in 1946 by Mokichi Kumakura in Kameido, Koto-ku, Tokyo, the birthplace of Edo kiriko.

Ryuichi Kumakura, the second generation, has been developing new patterns such as Kome Tsunagi (rice links), Itogiku Tsunagi, and Tama Ichimatsu and premium items that are highly artistic creations.

Our works are now used as gifts for state guests and commemorative items for international conferences such as summits, etc.

At the special summit meeting held in December 2023 to celebrate the 50th anniversary of ASEAN-Japan Friendship and Cooperation, a work by Takayuki Kumakura, the third generation, was presented as "a gift from Prime Minister Fumio Kishida to the leaders of invited countries and heads of international organizations”.

Everything from cutting to polishing is done in our own workshop, and all designs are created by our craftsmen. 

Hanashyo, the manufacturer and seller of edo kiriko, is particularly characterized by our practice of energetically creating our own pattern designs besides cutting traditional patterns. Our own typical designs include Itogiku Tsunagi (thread chrysanthemum links), incomparably finer and more precise than any edo kiriko from any other workshops, and Kome Tsunagi (rice links), which adorned the wine glasses used in an automaker’s TV commercials and presented to the state guests attending the Hokkaido Toyako Summit.

Today, most edo kiriko workshops employ acid polishing in the grinding process, which uses sulfuric acid, hydrogen fluoride, etc. However, the chemicals used are not just harmful to the environment but also scrape the surface of cut glass, reducing the glass’s shine. For this reason, at Hanashyo the entire processes are done by hand and the craftspersons grind edo kiriko by hand.
