Hamamatsu Castle (Hamamatsu-jo) was where the founding shogun of the Edo period (1603-1868), Tokugawa Ieyasu, lived for 17 years before he became ruler of Japan. As he lived in the castle during the time when he began a war for the purpose of uniting the whole country, it was also named the Castle of Advancement. https://www.jnto.go.jp/eng/spot/castles/hamamatsu.html

A new building housing "Brother Earth", a 35-meter-diameter dome planetarium, was opened in March 2011. The planetarium is the largest in the world. Also, be sure to check out our four large-scale exhibitions featuring an aurora film shown in a -30°C and a 9-meter tall manmade tornado! These attractions are highly entertaining and allow museum visitors to experience the power of nature. Additionally, the building itself acts as an exhibit through the use of solar power, green walls, visible earthquake-resistant structures and elevator mechanisms. http://www.nagoya-info.jp/en/see/facilities/nagoya_city_science_museum.html
