upsides versus walking: - 10x further distances - 10 blocks feels like 1, it's simply amazing. You can see parts of the city that are impractically far or bordered by boring/industrial zones.
upsides versus biking: - slow enough to "take in" the sights, where biking definitely feels like you've "lost" something. - more stable / feels safer - much easier to stop & start, and easy to lock up for a few minutes. - about the same speed as manual bikes (in practice) but slower than e-bikes
real downsides: - safety: if there's no bike lanes, then scooters can become hazardous. In particular, because they travel quickly, you can be safe one minute and then quickly have conditions degrade. The risks of medical attention vary by city - developing countries can have limited medical care; US medical care is $$$$. - disallowed & slow zones: it can be *VERY* annoying to have the scooter beeping at you, refuse to go, refuse to lock etc. And the GPS is imperfect, so you can be on the border of a legal zone and have it stop. I've had to walk scooters many times. - cargo: tough to carry significant cargo, e.g. groceries quickly become hazardous.
perceived downsides: - return-anxiety: what if there's no scooters? ==> rarely happens, but if so, then take an uber! - range-anxiety: what if it runs out of juice? ==> I've ridden a lot and never come close... - one scooter available for two people? ==> if you're careful, you can put two people on a scooter, then scoot to the next scooter (apps all have maps of available scooters)
Put another way, scooting is the "skip to the next track" of walking.
FYI, these are illegal to use in Japan without a license. They require the same license that low CC motor bikes/mopeds require in Japan. They also require license plates.
Are you riding a road bike that requires you be hunched over/encourages high speeds or are you riding an upright city bike? Because I mostly ride the latter and I think it’s a lot closer to the experience you describe with scooters.

Perhaps you have not ridden one very far then. I have encountered both of these problems at once riding across a downtown thinking there will be more live scooters on the other side and ended up with quite a walking journey back, uphill.
"It's too fast to be safe on the sidewalks, but too slow to be used in traffic. So I packed it back in its box and put it in a closet, never to be used again."
If the onsen you went to is the one I'm thinking of, I have some bad news: it closed in September of last year.

LaQua is probably the closest equivalent now in Tokyo, although it lacks the {kitschy,fun} Ye Olde Tokyo theme of Oedo Onsen. But hey, you get a roller coaster instead.
On a personal experience, when I arrived to Tokyo for a month long vacation in Japan, I had planned going to the Tsukiji Market tuna auctions that first day. It was about 2 in the morning, I had just gotten off a plane, not really tired but the jet lag would kill me for sure, so the plan to counter jet lag would be to not sleep that day and rest the day after and sort of get in sync that way.
Now, I don't know how it is now with the new market, but to be able to see the tuna auction you had to be at the market extremely early so, it being 2am seemed a perfect excuse to just walk. I walked for about 2h and when I arrived to the market I found out that day was a holiday in Japan and there would be no auctions that day. Disappointed, tired, I saw on google maps there was an Onsen nearby (around 1h30 away) so I kept walking to Odaiba. The Onsen in question used to be open something like 23h a day which was great for me at 5am.
Now that was one hell of a way to relax after that long walk. Never rested that hard in my life.
