Hot September

This summer was too hot. It is still hot even in September. But typhoon bring cool air into Tokyo area this afternoon.
We are worrying if it rains on today's tour, but it became clear and blue sky. Today is the best day for our tour in Imperial Palace.
Today's guest has come from Korea, and we can walk in comfort atmosphere.
Look at the picture, the sky is quite pure blue.
