• Spring (March–May): The most popular time, known for the sakura (cherry blossom) season, starting in March and lasting through April, with temperatures becoming comfortable. Late April to early May is also great for seeing other flowers like wisteria.
• Autumn (September–November): Often considered the best time, as the weather is dry and mild. October and November offer stunning autumn leaves (koyo) and comfortable temperatures for walking.
• Summer (June–August): Hot, humid, and rainy (rainy season is early June to mid-July), but great for festivals and fireworks.
• Winter (December–February): Cold but sunny, perfect for skiing in the north or visiting Onsens (hot springs) with fewer crowds.
