Toyota raised its annual net profit forecast by more than 10% to $9.3-billion on strong sales of the Camry sedan and other vehicles in its biggest market, the US, and on the yen's drop.
The world's biggest-selling carmaker posted a net profit of $1.1-billion for the three months to December 31, up by 23.5% from a year ago when it struggled after natural disasters disrupted its supply chain.
Among Japan's big three automakers - Toyota, Nissan and Honda - analysts see top seller Toyota as the most likely to benefit from a weakening yen because it has the highest ratio of production in Japan, more than half of which it exports.
The yen is trading at about 92 to the dollar, compared with 78 at the start of October.
The weaker the Japanese currency, the more money exporters make when they convert overseas profits back into yen.
This year, Toyota expects to sell 8.9 million vehicles globally.
Across the group, which includes Daihatsu and Hino Motors Ltd, it forecasts shipping 9.91 million vehicles.
Last year, the 75-year-old firm sold a record 8.72 million vehicles around the world.
Its group-wide sales were also a record high of 9.75 million vehicles.
Shares in Toyota have risen by nearly 50% since mid-November.
