1. The Nagasaki Atomic Bomb Museum
The atomic bomb museum is a must see for locals and foreigners alike. The devastation caused by the atomic bomb is out of this world and horrifying. The Nagasaki city website says that the museum serves as a powerful reminder of the true nature of nuclear weapons and of the pressing need for world peace. Seeing what it was like for the people in the vicinity of the explosion after the bomb is well documented in this museum, the struggles some people went through to survive, and a representation of the destruction caused to this area in Japan. Close to the museum is Nagasaki's peace park. Also a symbolism of peace after the bomb.
2. Mt. Inasa sights!
Mountain Inasa is a hill to the west of Nagasaki in which all of Nagasaki and its boat harbor can be seen from. There is a rope way travelers take from the shrine at the bottom of the hill to the top. Your view from the top is breathtaking. The night cityscape view is what made mt. Inasa famous, making it one of the top views in the world to see at night!
3. Pray for luck at Suwa Shrine
Suwa Shrine is the biggest Shinto shrine in Nagasaki. Not only is this place enormous but it's very traditional, old, and all major festivals and Shinto related events always have a celebration at the shrine. However, to get to this shrine please be in shape! The stairs are never ending and the only only water at the top in cleansing water :D
4. Seaside park, Dejima
Seaside park outside of the Dejima wharf is an amazing park that always has its fountains on, grass green, and families playing around it. The park is located right on the seaside and there is no better place to stop and relax. Big festivals like hanabi, and kunchi are celebrated here
5. Glover Gardens
Is a park in Nagasaki that was built for Thomas Blake Glover because of his work in shipbuilding , coal mining and other fields. The gardens are built on a hillside in an area with old restored Meiji period European homes. One of the most unforgettable aspects of these gardens is the giant koi pound at the top of the hill, a pound with hundreds of funny koi dying to play, is a dream here that needs to be experienced :)
