Ajinomoto brand is the product of a Japanese company known as Ajinomoto Co. Inc. primarily manufacturing monosodium glutamate ( MSG ) in addition to other types of seasonings, ready to eat meals, cooking oils, amino acids, sweeteners and pharmaceuticals. It is by far the most widely used seasoning across the globe for certain dishes of Japanese, Chinese, Korean and other East Asian cuisine.


Ajinomoto, monosodium glutamate, was discovered and patented by a chemist called Dr. Kikunae Ikeda and was first sold in Japan in the year 1909. The first production of Ajinomoto monosodium glutamate was done at the Zushi factory in Japan. Dr. Ikeda was on a two year stay in Germany, when he first stumbled upon the idea that there exists a fifth taste other than the standard four – sweet, salty, sour and bitter. He named this fifth taste Umami. He found this unique fifth taste of Umami in the Konbu seaweed and other dried fish based broth which contains glutamic acid salts and residues.

With a view to improve the overall nutritional health of Japanese people in every household, he wanted to explore the commercial aspect of production of monosodium glutamate. He approached Saburosuke Suzuki who dealt in iodine production, and together with him launched the production of this seasoning which became a household name in no time, giving a new taste to kitchens of many homes across the world.

Years ago Ajinomoto pioneered in innovative marketing technique by advertising on horse carts which were in use in those times, around early 1900s. They were also the first to distribute product samples, a completely new and unheard of concept in those times. A national campaign was launched to popularize the product by propagating with marching bands to create awareness among the retail shopkeepers. He also started the Road Stamp technique of promoting his product, under which the products were written about on the main roads with chalk, to invite public curiosity. The front runner for all these activities was Saburo Suzuki - son of Saburosuke Suzuki – who was all of 19 years of age.

Ajinomoto Co. Inc. was well aware of the importance of overseas sales and thus right from the very beginning emphasized the same. They started launching their main products in Taiwan, Korea and then to China. The sales of their products exceeded their expectations as it came to be widely used in restaurants, homes, canteens and food stalls. By 1916 they had opened their branch office in Shanghai and then in the following year in 1917 they opened their first branch office out of Asian shores in New

York, USA. By 1931 sales offices came up in Singapore, Hongkong, Taipei, Seoul and Dalian.
