> In Dutch culture it is far more common to keep shoes on literally everywhere
It is in many cultures, including my own family's, but having gotten used to taking them off from living in Japan, I find it extremely strange taking them off is not more common.
It feel similar to doctors refusing to wash their hands during surgery, though I get I'm not doing surgery.

I never thought about it growing up but once I got used to it I can believe I used to walk across my house carpet in shoes that had dog shit, grease, and other grim in them, and then later lie on my floor and watch TV or whatever. I don't get why people don't see that and get grossed out more.
Sure, if they were covered in mud or feces then I'd take then off but for small amounts I wouldn't notice. Why that doesn't matter to more people seems more strange to me than the status quo.
That said, I don’t think it’s really rational. Our houses are full of bacteria and dirt one way or another anyway. It’s impossible to avoid that without having some kind of airlock equipped with a shower in your porch.
True, but I don't know about you, but we don't have literal rocks, sediment, dirt pee, or literal poop on our floors in our home, anywhere. But shoes do occasionally step on stuff like that no matter how small, and neither of those things I want inside of my house on the floor.
But you're right that there still is bacteria or dirt all over the place, no doubt. But still, I don't step on something slightly soft with my socks in the living room and then inspect my foot to find poop stuck to it, and I think I'm gonna continue to prefer this way.
This is basically what dust is. It’s everywhere.
But ambulances in with full sirens begging over their speaker-system to have pedestrians at Shibuya crossing let the vehicle through, is probably the worst thing about Japan.
As for your second question, I’m reminded of Bob Mortimer in Would I lie To You: “… then the fire brigade came and ruined the whole house” - “Bob, surely the fire was ruining the house” - “No, water damage”. Maybe if those darn firefighters had taken their boots off, there had been a bit more left of Bobs childhood home.
Unfortunately ambulances in Japan blare their sirens any time they are transporting a patient, and because they are free some people use them like taxis. So you may see an ambulance at 2AM driving down a residential street blaring their siren at full volume, going 5 mph while the medics call around to various hospitals to see who will take their patient with an upset stomach.
Once I passed a moving ambulance with the siren on...while slowly riding my bike down an otherwise empty road.
The result is that Japanese people seem to tune out the siren. If the driver isn't also on the loudspeaker telling them insistently to move aside, they assume it's not a "real" emergency.
That's what we learned in fire fighting training. Everything that doesn't get destroyed by the fire and smoke will get destroyed by the water you use to put the fire out. A house on fire is lost. You just save people and animals and then you do whatever you need to protect the neighbouring structures.
Bob should have used some of his Fuji 9, that fixes everything!
