Yes, harahachi-bunme has been an incredibly useful tool for me, and has shaped my health for the better. I think that we all have days where we eat a bit more than we're comfortable with, but we don't need to be perfect all the time 😊 Just stay consistent with our healthiest habits.
It's unfortunate that we can't travel as we used to right now, but I hope that in the future some time you get a chance to visit! I'm biased, but I love Japan and love to share its culture with others. If you have any questions or further comments for me, feel free to email me at kokumura@kakikata.space!
