Feb 5 (Reuters) - Aflac ( AFL ) reported a

fourth-quarter profit on Wednesday that missed Wall Street

estimates, hurt by weakness in the health and life insurer's

Japan unit.

The company provides accident and pet insurance plans

through its units in the U.S. and Japan. It also offers

supplemental insurance for out-of-pocket expenses not typically

covered by major medical insurers.

On an adjusted basis, Aflac ( AFL ) earned $1.56 per share, compared

with the average analyst estimate of $1.62, according to data

compiled by LSEG.

The company's Japan unit reported adjusted sales of 359.9

billion yen ($2.36 billion), below estimates of $2.62 billion.

The insurer reported revenue of $5.4 billion, missing

estimates of $4.16 billion.
