Cold, snowy winters in north
In Northern Japan, particularly in Hokkaido and the north of Tohoku on Honshu Island, the climate is characterized by a humid continental type with long, harshly cold winters and heavy snowfall, especially on the west-coast regions facing the Sea of Japan. These areas have earned the nickname "snow country" or "Yukiguni."

This climatic condition significantly influences the lifestyle and culture of the region, marking it with unique seasonal beauty and challenges.
Cherry blossoms in spring
Cherry blossoms in Japan are blooming earlier due to Climate Change and urban warming, with records showing a shift in peak bloom dates by up to 11 days. Concerns are rising that warmer winters may cause some varieties, like the Somei-Yoshino, to face extinction by 2100. For more detailed information, you can explore this topic on The Independent, which provides an in-depth look at the implications of this shift on Japan's iconic cherry blossoms. These changes present a profound impact on cultural traditions and environmental landscapes, highlighting the urgent need to address climate challenges.
Autumn leaves in fall
Autumn leaves in Japan, known as "koyo," typically begin to change colors in mid-September in Hokkaido and from mid-October to early December in other regions such as Tokyo and Kyoto. This year, however, the 2024 season has experienced unusually warm temperatures, resulting in a delay of the peak foliage times. For those planning to visit, cities like Tokyo and Osaka are now expecting their best viewing periods around early December, offering a great opportunity for visitors to witness the vibrant transformation a bit later than usual.
Typhoon season: June to October
Japan's Typhoon Season traditionally runs from June to October, with peak activity between August and September. This period is characterized by powerful tropical storms that can bring strong winds, heavy rainfall, and significant damage, particularly affecting regions like Kyushu, Shikoku, and Okinawa. For travelers planning to visit during these months, it's crucial to stay informed about the weather conditions. Comprehensive information and tips for navigating the typhoon season can be found on the Japan Experience website, which provides valuable insights to ensure a safe and pleasant trip.
Varying regional climates
Japan's climate varies significantly from north to south, ranging from a humid continental climate in the northern region of Hokkaido with cold winters and warm summers, to a subtropical climate in the southern Ryukyu and Nanpo Islands with warm winters and hot, humid summers. The country also experiences different weather patterns between the Pacific coast, which has milder winters and hot summers, and the Sea of Japan side, which is known for heavy snowfall in winter.
