Nissan Motor said it would announce details of a voluntary early retirement program in Japan later on Tuesday, aiming to cut up to 1,500 blue and white-collar jobs amid a shrinking domestic market.

The scheme, to start in June, will be open to workers aged 45 and above in non-managerial posts, Nissan spokesman Simon Sproule said. A formal announcement will be made at 9 a.m. local time.
