The rainy season
The weather forecast says that the rainy season, Tsuyu(梅雨) in Japanese, starts to cover over Tokyo today. The season usually last about for a mouth and it doesn't rain all during the season. But it rains very frequently. I don't dislike the rain so much, but don't like the rainy season in June so much. The humidity, together with the hotness, makes the air sticky.
On the other hand, the discomfort weather make chilled beer very delicious! (Japanese prefer chilled beer partly because of the humidity weather.)
