If you love art and historical things, you should definitely visit Tokyo National Museum (東京国立博物館) which is Japan’s oldest and biggest museum. You can find four different galleries in the Tokyo National Museum, each housed in different buildings; The Main Gallery (Honkan), Eastern Antiquities Gallery (Toyokan), the Heiseikan Gallery and the Gallery of Horyuji Treasures.
I visited the Heiseikan (平成館) which is dedicated to Japanese archaeological objects. In the Heiseikan you will find all kind of statues, plates and even necklaces and other accessories made years ago. I especially loved all the Haniwa. Haniwa were made for ritual use and buried with the dead as funerary objects during the Kofun period. Sounds pretty creepy, but they’re actually adorable and friendly looking. There is English information available as well.
Tokyo National Museum is located in Ueno Park and is just a 10 minute walk from Ueno Station. The museum is closed on Monday but is open from Tuesday to Sunday from 9:30 to 17:00. During special exhibition periods the museum will be open until 20:00. Check their official website for more information. Entry fee is 620 yen for permanent exhibition and about 1000 – 1500 yen for special exhibitions.
