Can’t live without these Japanese conveniences.

Hey everyone. What Japanese convenience/service/item have you gotten so used to that you miss it if you ever moved back home? I personally think the toilets. Everything from the washlets to the generally clean and plentiful public toilets. I'm planning to visit home sometime this year and not looking forward to this aspect (ok, plenty other reasons to dread the US, but these toilet issues, especially the public toilets, will likely bug me), especially as I will likely spend a lot of time outdoors walking all over the place and not inside a hotel room. I feel totally spoiled here. Interested to know what others feel too attached to when it comes to the conveniences of Japan.
