This season

The number of hot days like summer is gradually increasing, but when I notice it, it's already summer solstice.
From tomorrow, the length of the day will be getting shorter every day.
I feel lonely, but as winter approaches, it's nice to have Japan where you can feel the four seasons.
From spring, this cherry arrives around this time when I'm tired of eating too much watermelon.
I love it because it's so delicious that it's incomparable to American cherries.
Is it in season now?
