Hakodate, in Japan, was a port city very early, so it was influenced by Western culture more obviously than other Japanese cities. For example, Wulinguo Park is a castle built in the Edo era in accordance with the Western architectural style. Its overall shape is a pentagonal star. Wulinguo presents a very unique beauty in all seasons. For example, in spring, it is full of cherry blossoms, in summer, it is full of lush green leaves, in autumn, there are red leaves blooming, and in winter, it is covered with white snow. When we went, it was winter. The whole Penglanguo Park was covered with snow. It was very dreamy. Visitors can climb up the viewing tower of Wulinguo and take pictures from the top. They can take pictures of beautiful, white Pentagon stars.
