Tokyo-based label Columbia Music Entertainment (CME) is buying software developer/distributor TDK Core.

TDK Core, also based in Tokyo, plans, produces and markets music, game and educational software. In a statement, CME says it decided to buy TDK Core in order to "to further enhance and diversify CME's future growth and corporate strategy."

"We anticipate being able to improve our management efficiency in several respects, including by integrating CME and TDK Core's sales channels, and by reducing production costs," the statement adds.

CME says the purchase will also enable it to boost its classical music line-up through the addition of TDK's opera and ballet titles, and strengthen its education business through the integration of TDK's learning materials, sales channels and intellectual-training products.

CME says the deal will also help boost its presence in the game business and in the visual-production field, which is growing steadily in the lead-up to the full digitization of Japanese television in 2011.

Although the sale price wasn't announced, the book value of the three million shares bought by Columbia from TDK Core parent company TDK Corp. totals 1.5 billion yen ($13 million). The purchase is scheduled to take effect Nov. 1.
