By layering two layers of fabric without applying a black coating, we were able to improve the UV protection and light blocking effect. It looks more natural, and both the front and back look cool and stylish.

The part that moves up and down when opening and closing the umbrella is called the "rokuro" and the joint part of the bone is called the "dabo."
The process of protecting each of these parts with the umbrella fabric is called "rokuromaki" and "dabomaki," and each part is carefully attached and covered to protect your hands when opening the umbrella and to prevent damage to the ribs, while also creating a traditional beauty and sense of luxury.
This is an old-fashioned technique that is time-consuming and therefore not seen much these days, but all of Komiya Shoten's long umbrellas are equipped with it.

The ribs are made of steel (iron that has been heat-treated). Steel is heavy compared to other materials, but it is a very strong material. Therefore, it is resistant to wind and has the strength to support the umbrella, so it goes well with fabric and can fully express the beauty of the umbrella's tension.
It uses a natural center pole made of maple wood, which is highly durable.
