I agree with some of your points such as trucks should switch from ICE but this will happen, you see company trucks start to advertise that they are hybrid and the buses are being switch to hydrogen buses. But Tokyo is hardly an industrial hellscape. You’re kind of describing traffic right near a major station but usually a bike commute to a major station can mostly be done on side streets, and in many areas you can do your shopping in shotengais (pedestrian only shopping street). It’s funny you mention gyms and dry cleaners because there are thousands of these in Tokyo, and small neighborhood has one. Your nearest one is unlikely to be a major station unless you live right next door to one. I actually like the no sidewalk small streets, they have no parking and while some are sketchy they are more often like a mixed use path where pedestrians clearly have the right of way.
