Arc System Works, developer of popular fighting games including the Guilty Gear franchise and Persona 4 Arena, has acquired the Technos Japan IP catalogue. These rights were previously held by Million, a small Japanese developer founded by ex-Technos staff, known best as the rights-holder for the Double Dragon and Kunio-kun franchises.
In the NES era, Technos Japan was on fire. Double Dragon was a hit series, and its Kunio-Kun franchise (which was released under a variety of titles in the West, including River City Ransom, Super Dodge Ball, and Nintendo World Cup) was a mainstay of the console.
The series revived in 2001, during the Game Boy Advance era when Million arose, under the stewardship of founder Kunio Taki, the former Technos CEO.
The companies have had a close relationship, and Arc has published a number of Kunio-kun games in recent years, including a smartphone version of River City Ransom called Kunio-kun Nekketsu Street.
It's unclear what the fate of Million is, in all of this; the company's homepage dates to 2007, with the most recent listed game release, a PlayStation 2 version of Super Dodge Ball, from 2006.
