THQ Japan will close its doors and end all publishing business on February 29 , as reported by Impress Watch.
As a result of the closure, all staff will leave the company as it shuts down. These measures are seen as necessary following the troubles faced by THQ in North America. Although there is no word regarding the publishing of future THQ titles, the company has been known to license its titles to local companies.
