AMBICO is a privately owned company specializing in Agricultural commodity and consumer goods.

The company’s journey was started back in 1971, so called the pioneer of Konnyaku farming and manufacturing in Indonesia.

Masaharu Ishii was one of the former Japanese Army who was sent to Indonesia. After the Japanese occupation era, most of the Japanese army were sent back to Japan. However, Mr.Ishii felt attached to Indonesia, decided to stay and fought alongside Indonesian people during the independency war

After Indonesia gained its independence, Mr.Ishii decided to start a family in Indonesia. As a form of gratitude, he tried to find a beneficial Indonesian commodity that could be introduced to the world and that could bridge the relationship between Indonesia and Japan. During period 1956-1965, he learned about the konjac trading industry thus made him the only trusted person to do the inspection for Japanese government in terms of exported konjac.

In 1971 Mr. Ishii built PT. Ambitious Trading Co. as a way for him to introduce konjac yam to the Indonesian people by processing it into Konnyaku and Shirataki.

The name of the company was inspired by the well-known motto :

“Boys, be ambitious!”


-William S. Clark.

Be ambitious not for money or for selfish aggrandizement, nor for that evanescent thing which men call fame.  Be ambitious for knowledge, for righteousness, and for the uplift of your people. Be ambitious for the attainment of all that a man ought to be.
