TBILISI, May 3 (Reuters) - Japanese Finance Minister Shunichi Suzuki said on Friday authorities may need to smooth any excessive yen moves that hurt households and companies.

"It's desirable for exchange rates to move stably. Excessive moves are undesirable," as they could have adverse effects on households and firms, Suzuki told a news conference on the sidelines of the Asian Development Bank's annual meeting.

"If there are excessive moves, we may need to smooth them out," he added. (Reporting by Felix Light in Tbilisi and Leika Kihara in Tokyo Editing by Tomasz Janowski)
