Even cherry trees aren't sure what to make of this year's run of unusual weather.

Cherry blossoms, which usually bloom in the spring, have recently been flowering across the nation, likely due to typhoons that brought in warm air and salty seawater, according to Weathernews Inc. and other experts.

The Chiba-based company said it received reports of the Somei-Yoshino variety of cherry tree blossoming from 354 people in 39 prefectures earlier this month.
