As a person who heve been for 2 days in Japan, I noticed that the city is super clean and the people are very friendly.. I must say that japanese people touched to my heart. They helped me without my demand when they saw a victim tried to find her way in underground :)
People are definitely very helpful here. They often tend to direct you or stay with you until they are sure you have gotten where you need to be or have completed what it is you are doing. I'm glad to hear they have touched your heart.
