In the early 1930s, Aladdin, a famous American brand, and an Englishman established a joint venture company, Aladdin. The prototype of the Blue Heater was developed by another company in the UK, and the companies later merged. Yanase Co., Ltd. started importing it to Japan in 1957, and it became a big hit in 1961 when it was introduced and praised in "Kurashi no Techo". Products that were originally made in the UK have been shifted to domestic production in Japan, and their performance has improved even further.
