WorkJam

In 1999, Data East licensed out the Tantei Jingūji Saburō series (aka Jake Hunter) to WorkJam.

In 2008, Aksys Games localized and published Jake Hunter: Detective Chronicles in the US, the first WorkJam title to make it out of Japan.

Following negative reviews due to its poor localization, it was remade and re-released as Jake Hunter Detective Story: Memories of the Past, this time to more favorable reception.

The title contained a remake of one of WorkJam's previous mobile phone games, Theresia: Dear Martel.

In 2011, WorkJam closed down, passing responsibilities for the part-developed Fukushū no Rondo to co-developer Arc System Works.

[8] 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.
