Verdant season
From May to June, Karuizawa is the most beautiful season of the year when the new green color increases every day and shines brightly. During the rainy season, we get enough moisture and trees grow. You can enjoy nature in a quiet and relaxing way ahead of the busy summer as a summer resort.
A forest bustling with wild birds
Narcissus Flycatcher and Blue-and-white Flycatcher come to Karuizawa to breed, and the Karuizawa Wild Bird Forest is crowded with birds who are busy courting and raising their children. You may even hear the chicks.
Encounters unique to the highlands
In Karuizawa, situated approximately 1,000 meters above sea level, visitors can admire highland flowers such as the town's designated flowers, primroses, and Blue Siberian Squills. The Kousa Dogwood, with its lovely white bracts, heralds the arrival of the rainy season in Karuizawa.
What the rainy season brings
It is said that phytoncide, a scent component of forests, actively dissipates from spring to summer in the morning and after rain. The sunny periods of the rainy season are the perfect times to take a walk in the forest.
A feast fostered by mist
Karuizawa lettuce, introduced by foreign missionaries during the Meiji period, benefits from the morning mist formed by the temperature difference between day and night, resulting in a fresh and sweet flavor. This makes it a delightful treat for early summer, coinciding with the start of the harvest season in June.
