I wouldn't have posted here if I didn't expect harsh, so I don't take it personally.
Hideki didn't spend most of his life abroad, but I understand my audience is not Japanese. What looks "atypical" to him needs to be pointed out to the reader. I understand this is outside of Hideki's viewpoint, but I don't expect readers to know that Suu is considered very overweight in Japan, when she wouldn't be considered by such an extreme in the US.
I understand that it's simply "language" in Japan, but again, my readers are not Japanese, nor is the book written in Japanese.
I apologize if I've misrepresented Japanese vending machines, but I did research that actually and believed I was being accurate when it comes to warm food being served...
As for the building, I did mistype by not saying "Japanese-style", it's obvious the building is in Japan, but I was trying to convey that it was a traditional style of architecture. Again, I don't expect my readers to know Showa-period from Heian-period by name, and I don't want to bog them down with details they don't need.
As for the LGBT points, this is something I've researched heavily, and I have spoken to LGBT people from Japan (more gay than trans, because it's more relevant to my writing). Much of my research was actually on LGBT students and their personal experiences, including bullying, but worse yet was dealing with teachers who were entirely unequipped to handle their situation. The statistics of LGBT youth in Japan who have been bullied, were taught in school that it was "deviant behavior", or self-harmed or attempted suicide as a result of their treatment, are chilling. While Japan is taking steps and growing (just last year they let a gay couple become foster parents), they still have a long way to go, and there's a serious lack of information both for LGBT youth and those responsible for their education.
My goal is not to cast Japan in a bad light. The episodes involving the subject (which won't come up til book 3 actually) avoid generalizations, and show peoples' opinions from all angles (a concerned teacher who doesn't know how to help, people who are more comfortable ignoring it than addressing it, characters who are concerned for a friend but who've never known an openly gay person except for a silly stereotyped character on a sitcom, etc). I love the culture and I appreciate the steps they're taking, but there's still a lot of progress to be made.
