If you ever lived in Japan for over a year you would have seen the weather pattern follows a distinct set of seasons. Of course there is Spring Summer Fall, and Autumn. But another season that many people find one of the worst weather times of year that splits spring and summer is the rainy season.
The flowers come in all sorts of colors. Typical colors are purple, blue, white and shades of colors in between.
The flowers last from June to Early July across Japan before fading away at the onset of Japans summer season.
If you are in Japan during this time you can find the flower just about anywhere, but the best place to see it is in Kamakura where it surrounds numerous temples in the formal capital of the country.
