The former president of a nationwide chain of day-care centers was sentenced Wednesday to a suspended one-year prison term for professional negligence resulting in the death of a 4-month-old boy.

Another former executive was sentenced to a suspended 10-month term. Both sentences were suspended for three years.

The Tokyo District Court handed down the sentences to Masamitsu Maekawa, 55, former president of nursery chain Chibikko-En, and Kozue Maedomari, 38, a director at the Toyama-based company.
