Japan's dramatic north-south extent across 3,000 kilometers creates extraordinary climate diversity, from the sub-Arctic conditions of Hokkaido to the subtropical warmth of Okinawa. The country's island geography and surrounding ocean currents — the warm Kuroshio from the south and the cold Oyashio from the north — produce complex weather patterns. Japan experiences four distinct seasons, each celebrated in the culture, from cherry blossom season in spring to the vivid autumn foliage.
