Especially in Tokyo it is quite impressive (subjectively, from European perspective):

• Swimming pools and onsen on the top floors of large buildings
• construction sites that seem to be worked on 24/7, it never seems to be empty
• trains and public transport that arrives ON POINT
• most people get along with each other very well
• there is a larger “basic politeness”
• it is safe
