This isn't an account of the cultural moment that indi-fashion hub Harajuku had before its gentrification by Major international brand stores, or a inane J-Travel blog complaining about being out of shape and there being too much walking, It's a possibly interesting story of personal growth only coincidentally related to Harajuku.
I didn't know what Harajuku was, and thought it was going to be some Japanese term for some psychological concept, like ikigai, kaizen, wabi-sabi, or something like that.
Disappointingly, it's about personal shrinkage - weight loss. Yes, you have to want to do it; people fail because they get hungry, and that can be surprisingly hard to fight. The magic GLP drugs work because they suppress hunger, at which point not eating becomes easier.
Took a really long time to get to that point.
