The national museum of nature and science is made up of two main galleries. The Japan gallery is a great way to learn about the nature and history of the Japanese islands along with how Japanese people and their culture has evolved throughout the years. The global gallery showcases Japanese inventions and their progress in science & technology. Next to the biodiversity exhibition, there is an exhibition on the evolution of dinosaurs which I found quite interesting as it has real dinosaur fossils. The building and its exhibits are up-to-date and very well maintained. Expect to spend a few hours at this museum.
