TOKYO, May 10 (Reuters) - Japan's Honda Motor said on Friday its fourth-quarter operating profit grew more than six fold from a year earlier, helped by a weak yen and strong vehicle sales.

Japan's second-biggest automaker by volume saw quarterly operating profit come in at 305.6 billion yen ($1.96 billion), versus an average estimate of 248.3 billion yen in a poll of nine analysts by LSEG. ($1 = 155.6200 yen) (Reporting by Daniel Leussink; Editing by Christopher Cushing)
