"Putin has expressed condolences to Japanese Prime Minister Shinzo Abe over the significant loss of human life caused by the series of destructive earthquakes on the Kyushu island. The head of the Russian state has expressed condolences and support for the families of those killed, wishing those injured in the natural disaster a speedy recovery," the Kremlin's press service said.
At least 37 people died and some 2,000 others were injured in a series of powerful earthquakes that hit Japan in past days.
A magnitude 6.5 earthquake struck southern Japan, near the regional capital of Kumamoto on the Kyushu island, on Thursday. Early on Saturday local time, a second earthquake struck the same island, registering magnitude of 7.3. Some 100,000 people have been evacuated.
On Friday, Russian Foreign Minister Sergei Lavrov said that Russia was ready to provide assistance to Japan.
Japan is seismically active region. In March 2011, a 9.0-magnitude offshore earthquake caused a 46-foot tsunami which hit Japan's Fukushima nuclear power, leading to the leakage of radioactive materials and the shutdown of the plant. The accident is considered to be the world's worst nuclear disaster since Chernobyl.
