Reiwa era started here. We're halfway through our Golden Week(almost 10 days this year)
He may keep that ramen hair to remind him of ramen while competing, as Misha suggested!:dev3:
For some reason, it appears to me that some boys in Japan feel they have to have their hair like that at least once in their lifetime or something. AQFS, you may have to get over it at least for another while

As for the last Heisei photo, his SEV neck really stands out, especially when Koshiro's wearing his colantotte(from his mom, I read).
If I'm guessing correctly, I think they have had some annual athlete check (physical exams on designated skaters by JSF) in Tokyo, which will be broadcasted partly by BS Fuji on May 3rd. (But
that ramen shop is in Osaka, maybe they traveled back to Osaka together?)
Regarding 4Lo, yeah I agree that Hanyu-kun's landing was extremely scary, but I'm also scared of a fall before jumping, as I recently read in one of "aru-aru (happens-all-the-time)" list articles (of Men figure skating in Japan) in
this ex-skater's blog. (Scroll down to see a gif of fall before a loop jump, that's very scary too)
What Hanyu-kun said in an interview after WC, that edge jumps get affected by ice conditions quite easily compared to toe jumps, is another concern. But not like I know much about jumping quads anyways, so I'll just trust him and his team, and wait patiently to hear how it works out for him!
