U.S. discount retailer Wal-Mart plans to take control of Japanese retailer Seiyu by increasing the percentage of its shares, giving it a full 50 percent of the company. And Japanese business confidence is up, but not as high as expected.

Wal-Mart plans to take control of the Japanese supermarket chain Seiyu by the end of the year, and turn it into a subsidiary. The U.S. retailing giant will buy shares worth $597 million, which will give it just over 50 percent of the company.

Wal-Mart has been slowly raising its stake in Seiyu, which has more than 400 stores in Japan. But Seiyu has struggled and lost money, which sparked Wal-Mart's decision to take control.

The cuts will mostly affect the agriculture and health ministries. The government will not make any cuts to the Self-Defense Forces.
