Tanabata is celebrated on July 7, also known as the Star Festival. Last year, I attended the Shonan Tanabata Festival in Hiratsuka, Kanagawa Prefecture. There is an old tradition to write down a wish on a piece of (colored) paper and tie it to a bamboo tree.
Below are two pictures I took just before we left Japan last week.
Hope you had a great Tanabata Day in Japan.
