Yamaha Motor Co Ltd today reported sales of ¥405.6bn for its first quarter ended December 31, 2018, a 5.1% gain over the previous year. Net income was up 2% to ¥32.4bn. The appreciating yen had an impact on sales, though the company said that growth in its marine, motorcycle and industrial machinery segments absorbed that impact.

Yamaha’s marine segment had sales of ¥91.5bn, up 5.9% compared to the same time a year ago. Operating income was ¥20.3bn, up 12.8% for the quarter.

An increase in North American personal watercraft sales drove most of the quarter’s growth, according to the statement.
