The days ranged from wonderfully sunny and warm and humid to rainy and stormy due to typhoon season. The air temperature remained at twenty degrees Celsius. Wearable, but you must be able to withstand hot and humid weather.— This text has been automatically translated into English

One day you might enjoy a pleasant temperature of 15°C, the next day you should have an umbrella handy. The weather was rarely ideal, sometimes sunny, often rainy. Because of the weather, November is not the best time to visit Japan.— This text has been automatically translated into English

Weather Experience: Moderate StarStarStar

Lots of snow in the north and fairly cold weather in the south. The problem is when you have travel plans. Ski conditions are excellent, but can be uncomfortable for non-skiers.— This text has been automatically translated into English

Cool, clear, blue skies alternated with glorious sunshine during the day and light snow in the evening. The temperature dropped considerably and a warm coat was required. No crowds, perfect!— This text has been automatically translated into English
