Even in summer, average temperatures rarely rise above +20°C, and evenings can be quite fresh. In winter (from December to February), the average temperature holds around -5°C, so a warm winter jacket, hat, scarf, gloves, and thermal underwear will be absolutely essential.

In the summer months (June-August), you will need light sweaters, t-shirts, and trousers, but be sure to bring a windbreaker or light jacket. August stands out with the highest amount of precipitation, so a good umbrella or raincoat will become your faithful companions.

Sunscreen may also be useful on clear days, especially in spring and summer.

Regardless of the season, it is worth bringing a small backpack for day excursions, where you can put an umbrella, an extra layer of clothing, or a bottle of water. Considering that even in months with a small amount of precipitation, a significant number of "wet days" is still observed, readiness for light rain or drizzle will make your journey around Kushiro much more comfortable.
