From Military Bugles to Electric Horns
140-Year History of Miyamoto Horns


~Records of Miyamoto who never gave up its horn manufacturing during turbulent times~

In 1872, Miyamoto's founder turned himself from selling Copper Boilers to Bugles.

In 1863, there was a weapons manufacturing plant of the former shogunate in Sekiguchi-cho, Koishikawa and the Meiji government founded an army in 1872 (Meiji 5th).
When shifting itself into a modern western-style army, it began to make foreign-style bugles for signals under the instruction of commanders invited from France and Germany.
Our founder, Katsunosuke Miyamoto, who happened to be running copper boiler (copper oven) shop, began to make bugles after he was hired by an officer in charge of military bugle production.

From the late Meiji era to the Taisho era, Miyamoto began to make car horns.

Around 1905, Miyamoto was asked to repair a motorcycle horn, which led Miyamoto to begin manufacturing traffic horns. At that time, Japan started to import automobiles, and Miyamoto started receiving orders for the production and repair of horns.
The installation of a friction screw press improved production efficiency than manual operation and Miyamoto embarked on exporting.

From the early Showa era to the end of World War II, Miyamoto began to manufacture electric horns.

Around 1931 (Showa 6th), Miyamoto began to manufacture Japan's first electric horns, but faced a shortage of goods and materials as the war expanded. The annual production of electric horns around that time was approx. 6000 to 7000 pcs. The number of employees dropped to under 20 due to the draft and relocation.
Due to the wartime control of materials around 1940, Miyamoto became the only company manufacturing air horns until the defeat of the war in 1945. When the war ended, Miyamoto stopped producing air horns.
In March of 1945, Miyamoto's factory in Edogawa was entirely destroyed by the Great Tokyo Air Raids.

Words of Fourth President, Kuraji Miyamoto

四代目 宮本庫治

The fourth president, Kuraji Miyamoto, who saved the company in the turbulent periods of before, during and after World War II left the following words:
"A person who only focuses on and pursues their own interests and profits is not qualified for running a company.
In this world, happiness and peace for individuals and the society can be maintained by people considering public interests, and the world seems to be moving toward that direction."
