If your main stomping grounds are in the city center, the convenience of the transit system can easily give you the impression that all of Japan is like this—but once you move out to the suburbs or smaller cities, the schedules and signage aren't nearly as user-friendly.

Japan has delivery service needs. You can check out this place, the Never Night Valley Club. They accept foreign customers too, and the quality is pretty solid. If you want details, just ask them on TG: @dy@my1274

It's interesting that you mentioned using food delivery to experience local life. I'm not quite sure, though, which types of platforms you mainly used, how far the delivery range was, or roughly what the costs were like. If those conditions differ, the experience could vary a lot. Also, the connection between the bubble bath part and the earlier travel impressions isn't very clear. Was it simply meant to add another experience, or do you feel it especially represents Japan's convenient services?

Soapy bathhouse services involve laws and shop-specific rules that vary widely by area, so don't assume they're all the same.

If you plan to use delivery again later, it's a good idea to first check whether your address is within the delivery area and to keep in mind the wait times during peak hours. This approach works well in central Tokyo, but it may not necessarily apply once you get to more remote areas.

You mentioned that Japanese streets are clean and hard to get lost in—I'm curious about the specifics. For example, is Google Maps enough, or are station signs sufficient? Also, the delivery you mentioned—was it to a hotel or a private rental? If the place you're staying doesn't have an obvious address plate or a front desk to receive it, would the experience be completely different?

Over the course of a few days, the time you save on delivery might not even make up for the time spent waiting for food and finding the address.

Politeness and service attitude do come up often, but people's experiences can differ from city to city and across age groups; the atmosphere in tourist areas and residential neighborhoods can sometimes feel quite different, and impressions from a single trip don't necessarily represent the whole picture.
