The Russian currency has plunged by about 50 percent against the dollar so far this year, raising questions for global auto makers operating in the country.
Russia is Nissan's fifth-largest market and the Japanese firm's alliance with Renault SA, of which Ghosn is chairman and CEO, gives it a majority stake in Avtovaz OAO , Russia's largest automaker.
Ghosn told reporters Nissan is gaining market share in Russia, and the group is raising prices on some Nissan and Renault models on sale there that have high levels of foreign content.
He has said that he wants to triple sales in Russia in the next three years.
