Toyota has agreed to give the biggest wage hikes in two decades, in an early sign of momentum in pay gains as Japan's central bank looks for evidence of a wage-price cycle that could lead to policy change.

The company agreed to increase pay including base wages and bonuses at the first round of negotiations, the company said Wednesday. The deadline for reaching a conclusion to the negotiations wasn’t until March.

This is the third consecutive year the world’s biggest automaker has met union demands in full, the company said.

Wages have taken center stage in Japan, with the Bank of Japan having indicated that it must see stronger wage growth to ensure that the trend in prices is sustainable.

The BOJ has a 2% inflation target, but even with key prices rising at 4% in the economy, the central bank is remaining committed to its massive stimulus program until wages also show larger gains.

Toyota said bonuses this year would be equal to 6.7 months' salary. It didn’t give a breakdown of the percentage increases in pay for workers defined under numerous categories. The union said the wage increase was the biggest in 20 years.

Kazuo Ueda is the government’s pick to take the helm of the BOJ in early April amid simmering market speculation that a policy change may follow, a shift that would impact markets around the world.

Current BOJ Gov. Haruhiko Kuroda has indicated 3% wage growth is necessary to support stable inflation of 2%. As labor negotiations draw to a close, some of the country’s biggest companies are announcing increases in salaries, base wages and bonuses for the next year.
