"In 2013, we see Japanese automakers further cutting production with lost output likely to hit 350,000 units in 2013 and 300,000 units in 2014," Chow said, adding however, that the recent "sales dive does not mean that they have completely stopped selling models".
She said that Nissan and Toyota, in particular, which have the biggest stands at this year's event are using the occasion to show they are still major players locally, taking more floor space than ever before.
Toyota said it will exhibit more models than usual on a 4,500 square meter stand, 10 percent larger than last year, including its new flagship Lexus sedan.
Japanese rivals Honda and Mitsubishi will also be there in force, with the former choosing to focus on its luxury Acura brand, and the latter bringing its latest models.
Given the recent issues, Chow said their involvement at this year's show is all about "strengthening brand awareness of their products in the hope that they regain some of their market share".
According to IHS, South Korea's Hyundai will be using the Guangzhou event to strengthen its presence in southern China, with displays of all its most recent vehicles.
