Japan's exports of used vehicles to Russia, exempt from sanctions imposed over Moscow's invasion of Ukraine, have surged to their highest level in more than a decade.

Moscow's success in keeping the ruble strong despite sanctions has also boosted Russians' appetite for used high-quality Japanese vehicles, which can be exported so long as they are worth less than ¥6 million ($43,400).

Japan's total exports, by value, of secondhand cars to Russia in June were the highest on record since January 2009, according to government data.
