Square-Enix have gone for an EA approach, and have outlined plans for a Friendly takeover of fellow Japanese Games-Makers Tecmo.
According to Kotaku, today Square-Enix has released a statement explaining the Tecmo takeover plan. You can find shots of the statement in Japanese here and here.
[The Statement] includes offering to purchase a controlling interest in Tecmo by purchasing shares in that company at 30 percent premium (�960 a share compared to yesterday's close price of �706 a share). The Tecmo Board of Directors has until September 4 to approve or reject this offer. If rejected, Square states, "We will withdraw our offer."
It is speculated that Square-Enix are going after Tecmo in a bid to strengthen their Western offerings, and to boost their portfolio, which now mainly consists of Role-playing Games.
This wouldn't be the first company Square have bought out. In August 2005, Square Enix acquired Taito and wholly owned the company as a subsidiary by the next month.
