I think in Japan she would be considered obese.
edit: that sound harsh but in Canada obesity is quite easy to attain like I'm 6ft 190lb and I'm technically obese even though I'm only slightly chubby. And I know in Japan it's stricter.
Was about to comment on this too. multiple passages made little sense,and I can imagine it's because of the original Japanese wording making it confusing when directly translating it. But it could be beneficial to review and correct those parts and make them coherent.
