This is a very neat and tidy museum. Every exhibit is well set out and well lit. It has a theme of overseas exchange and displays much of Nagasaki's early history when it was a treaty port.
Located nearby Nagasaki Station by bus or train. Opened about 10 years ago and very clean. We can know about nagasaki culture with China, Europe and the Kyushu, also Christian history. Famous traditional cafe(Ginrei) inside.
This museum displays key history events of Nagasaki. Exhibits are well-organized for better insigths and understanding. If your timing is right, you may want to pay a few hundred yen to watch a short performance. When exiting the miseum, do stopover at a cafe next to the museum. They serve excellent local specialty desserts and coffee.
