In the face of slowing global growth, the carmaker has been trying to cut costs and improve productivity at its factories. It has also faced a string of recalls in recent months.
Earlier this week, the firm announced a recall of 320,000 trucks and SUVs over problems with airbags, saying they could inflate without a collision.
In November last year, it recalled 1.6 million vehicles equipped with faulty airbags. In October, it recalled 6.5 million vehicles over a faulty window switch.
The Japanese carmaker has recalled about 15 million vehicles fitted with the bags since 2013.
On Friday, it also announced a share buyback of about 150bn yen worth of outstanding shares.
Despite the recall worries, Toyota won back the crown of the world's largest carmaker by sales in the first nine months 2015 from Germany's Volkswagen.
