There are two types of unique mosquito coils in Japan. Firstly, one of the Japanese mosquito coils which is called “Kayaributa” is very unique because of its shapes. “Kayaributa” looks like a piggy bank, but the piggy style is not for saving money.  “Kayaributa” is a tool for putting mosquito coils its inside and also it looks like pottery. Probably, many Japanese will come up with summer when they see “Kayaributa”.


Secondly, the mosquito coils which are made by Dainihon Jouchugiku Co. Ltd is very famous and traditional one. Dainihon Jouchugiku Co. Ltd was established by a Japanese businessman, Eiichiro Ueyama in 1880s. Ueyama got a plant which is called Pyrethrum, using for the natural insecticide at that time from an American businessman in 1880s. The flowers are mixed with water after dried and crushed. It`s the oldest insecticide in the world, but Pyrethrum has been used for natural and not harmful insecticide for a long time.

Ueyama developed the mosquito coil which is made by Pyrethrum and he created a very unique type of mosquito coil, stick shaped mosquito coils. The stick shaped mosquito coil was a new blockbuster product at that time, but stick shaped mosquito coils burned up very quickly (it was burned up only 40 minutes) and it was not effective for repelling mosquitoes. After years of trial and errors, Ueyama finally came up with a more effective shape of mosquito coil, looks like a spiral shaped mosquito coil in 1890s. It was continued to burn up about 7 hours, and Ueyama`s ideas actually came from his wife Yuki (Yuki demanded Ueyama to create longer and thicker, spiral shaped mosquito coils because she saw a big snake near her house and her idea came from the snake).

The spiral shaped mosquito coils are widely used in many countries, such as Southeast Asia and it helps a lot of people from mosquito diseases, for example, Malaria.
