Tokyo Broadcasting System Inc., the target of an unwanted takeover bid by Rakuten Inc., said Tuesday it has asked the Internet mall operator for more information about its intentions.

The 25-page request by TBS comprises 27 questions, including requests for detailed information about the ultimate objective in raising its stake in TBS above 20 percent, its proposal for a business alliance, and negative effects that may result from collaboration between the companies.

The broadcaster did not set a specific deadline for a reply.
