WorkJam

WorkJam Co., Ltd. (株式会社ワークジャム Work Jam Co., Ltd.) was a Japanese video game and software development company. Its main headquarters were located in Chiyoda, Tokyo.

History
WorkJam was founded by Yutaka Kaminaga on December 15, 1998. In 1998 they released their first title in Japan, an adventure game titled Cross Tantei Monogatari. In 1999, Data East licensed out the Tantei Jingūji Saburō series (aka Jake Hunter) to WorkJam. In 2002, it released the first of these licensed games, titled Tantei Jingūji Saburō: Innocent Black. Full rights to the series were given to WorkJam after Data East went bankrupt in 2003.

In 2011, WorkJam closed down, passing responsibilities for the part-developed Fukushū no Rondo to co-developer Arc System Works. The company's social game business was purchased by CommSeed and Cykan Holdings at the end of the same year.

On February 6, 2017, Arc System Works announced that they had acquired the rights to all of the ex-WorkJam properties which had passed to Expris, namely the Jake Hunter, Theresia, Nazo no Jikenbo, and Koneko no Ie series.
