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 Bunkyu 3 (1863), there was a weapons manufacturing plant of the former shogunate in Sekiguchi-cho, Koishikawa.  The Meiji government founded an army in Meiji 5 (1872), and 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 operate a copper boiler shop (copper oven) began to make bugles after he was hired by an officer in charge of military bugle production.

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

Around Meiji 38 (1905), Miyamoto began to manufacture traffic-related horns after being asked to repair a motorcycle horn.
Japan started to import automobiles around this time and Miyamoto was asked to repair and produce horns.
With the installation of a friction screw press, Miyamoto achieved more efficient operations than handwork, and thus embarked on exporting to overseas.

Miyamoto began to manufacture electric horns in the early Showa era to the end of World War II

Around Showa 6 (1931), Miyamoto began to manufacture Japan's first electric horns, but faced a shortage in goods and materials as the war expanded.
Around the time, the annual production of electric horn was approx. 6000 to 7000 pcs.
The number of employees dropped to under 20 due to the draft and relocation.
The supply of goods was controlled around Showa 15 (1940) and Miyamoto became the only company manufacturing air horns until the defeat of the war in Showa 20 (1945). When the war ended, Miyamoto stopped to produce air horns.
In March of Showa 20 (1945), Miyamoto's factory in Edogawa was entirely destroyed by the Great Tokyo Air Raids.

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:
"Man who focuses and pursues only his own interests and profits is not qualified for running a company.
