Koizumi Lighting

Koizumi Lighting is the lighting-related business of Koizumi Sangyo Co., Ltd. (小泉産業株式会社), a Japanese company whose origins the company traces to 1716, when merchant ancestor Koizumi Tahei began peddling hemp cloth. The company states that in 1946 it changed its name from Gokō Seiki Kōgyō to Koizumi Sangyo Co., Ltd. and began full-scale manufacturing and wholesale of household goods including electrical products. Its lighting roots are described as beginning in 1947 with electric stands, and in 1965 the company promoted interior lighting under the catchphrase 'lighting is interior.' The company describes its business as supporting the creation of spaces in homes and workplaces through lighting and equipment technology and products, under the brand statement 'there is a different way of thinking.'

The company traces its origins to 1716, when its merchant ancestor Koizumi Tahei began peddling hemp cloth, a specialty of Ōmi, after giving up farming. In 1738, the sixth-generation Koizumi Shinsuke opened 'Ōmiya Shinsuke Shōten' in Gokashō, beginning a full-fledged hemp cloth business. In 1847 the business opened a kimono and fabric store in Kyoto. In 1871, it opened 'Tachikiya Morinosuke Shōten' in Osaka's Senba district, a year the company calls its first year of modern founding. In 1904, 'Koizumi Gōmei Kaisha' was established with investment from five family managers. In 1946, the company changed its name from Gokō Seiki Kōgyō to Koizumi Sangyo Co., Ltd. and began full-scale manufacturing and wholesale of household goods including electrical products. Its lighting roots are described as beginning in 1947 with electric stands, followed by cut-glass stands, Japanese-style stands, and fluorescent stands. In 1953 it developed a kerosene stove and began selling it through electrical appliance stores. In 1960 it moved into sinks, and in 1962 it proposed hair dryers for the general consumer market through electrical appliance stores. In 1965, under the catchphrase 'lighting is interior,' it brought design into lighting fixtures. In 1966 it launched the industry's first study desk with a fluorescent lamp, 'Keisetsu,' and in 1967 the dining table 'Bansan.' In 1970 it established a furniture division, and in 1971 it aired a TV commercial for study desks and launched the 'Rider Desk' with lighting.
