TOKYO (Reuters) -Toyota Motor did not respond to a trade union’s wage demands in a second round of pay talks held on Wednesday, a senior union official said, keeping investors guessing about the outcome of closely-watched annual wage talks due on March 13.

For the past two years the world’s biggest automaker has accepted the union’s demands in full at the first meeting, which has long served as the pace-setter for Japan’s spring labour-management wage offensive called “shunto”.

“We did not receive a response to our pay demand today,” Hiroki Akiyama, a senior Toyota union official, told reporters.

Last week, Toyota said it would continue negotiations with the union after the first round of talks.

Instead of reaching a pact on wages and bonuses, the company and union deepened their debate over workplace issues on Wednesday, Akiyama said, adding, “We will continue negotiations into next week.”

In contrast, Honda Motor, Japan’s second-largest automaker, responded in full last week to union demands for a record rise in base pay and bonus payments.

Toyota’s third labour-management meeting is set for March 6, before a formal offer for 2024 pay hikes on March 13, along with other blue-chip Japanese companies.

Economists project hikes of about 3.9% on average from big firms, exceeding a 3.58% pay rise deal struck in 2023 that was the highest in three decades.

This year’s labour talks are being closely watched by the Bank of Japan, which sees sustainable wage and price hikes as a prerequisite to normalising its ultra-loose monetary policy and ending negative interest rates.
