It’s been notably less pleasant for the last two years, for reasons shared with substantially all cities (ex-China, I suppose). Would heartily recommend it otherwise, which would have surprised me when I was younger. In particular, the neighborhoods allow you to pick your vibe, pace, and sense of scale at multiple points along the continuum, so if e.g. the Shibuya scramble crosswalk is not your idea of a good time you can live five minutes away by train and enjoy tree-lined streets and cozy bistros with a bit of outdoor seating instead.
