The Yamauchi No. 10 Family Office (YFO), which manages the fortune of the founding family of videogame legend Nintendo, ended a long struggle to gain control of the marine engineering firm Toyo Construction.
The decision comes in the wake of Toyo's move last week to reject YFO's latest offer due to a price of 1,255 yen ($8.73) per share, which is lower than the stock price around early December.
The decision surprised some, since YFO-backed directors have had a majority on Toyo's board since June.
The two sides differed in their growth strategies, with Toyo having an ambitious five-year plan that looked beyond Japan and YFO pushing back that the overseas plans were too optimistic.
Toyo's shares hit a year-to-date high of 1,372 yen in November but fell after the company announced its opposition to the tender offer, closing at 1,207 yen Wednesday.
