"On how to keep up with growing demand for digital cameras, Kariya said Nikon is planning to raise output capacity at its plant in Thailand.
"At one point, there was discussion that we need to set up a new plant," he said. "But our Thai plant's productivity has been growing very fast in recent months.
"We believe there is still room for the plant to raise its output from the current monthly volume of 300,000 digital SLR cameras and 300,000 lenses."
For the future, Kariya said Nikon, which marked its 90th anniversary this year, will also consider whether it can strengthen its production capacity in Japan.
The Thai plant, with about 14,000 employees, is producing almost all of Nikon's digital SLR cameras, excluding the flagship D3 model.
In contrast, Canon is manufacturing all of its digital SLR models in Japan and Uchida said it has no plans to produce them abroad.
"I think it would be better not to take digital SLR cameras outside Japan" as the company now has a wide range of models and could save a great deal of time in designing and marketing new products if they are produced at home, he said."
