ActuaBD.com is among those sources reporting that Delcourt has acquired Tonkam, an imprint with over 600 titles. The article provides a brief history of Tonkam's contribution to the rise of Japan in Europe, painting it as one of the early market participants (mid-'90s) and pointing towards its broad range of material, including shoujo manga, comics from China and Tezuka's Buddha series. The article also says that Delcourt plans to largely leave the imprint alone, although I have no idea if that's customary to say in France when you buy a business the same way it is in North America or not. Delcourt has its own manga titles, I believe, so that may prove to be a factor as well.
