My first visit to Japan left me in culture shock, but I wish the US would adopt some of its norms

• In Japan, I saw how the local culture and etiquette are different from what I'm used to in the US. 
• With self-cleaning toilets and an absence of trash, Japan models an impressive level of cleanliness.
• The public toilets and hotel freebies in Japan were also far superior to what I've seen in the US. 

As soon as I arrived in Tokyo to a near-silent Narita Airport, I knew I was in for a bit of culture shock.
