I don't understand why I would need an <input type=year> to get this right
though. If the bank wants something in 年号 it can just let the user type in
1985 and convert that via JS to 昭和60年, no? If anything, having some sort of
picker seems like it would be more complicated.

Frankly, this seems a bit over-complicated. The number of times a user will
be entering a year other than 1900->present has got to
be infinitesimally small. In reflecting upon the years I've entered, it'a
almost always been a living person's date of birth, some event I was
scheduling, a date for something I was purchasing (e.g. airline ticket), or
the present date.

I really don't know if it's worth spending time on something that is such a
minor use case, and can frankly be handled fine without a dedicated input

And niwa-san, on every document I've ever filled out for the Japanese
government, I've always written 1985年 instead of  昭和60年 and it's yet to
cause me any problems ;-) I do understand that there are some sites that
want it written in the traditional form, but these seem to be precious few
and far between, and frankly are not the sites I would expect to find HTML5
form input elements on anyways if the US government is any indication of
moving to new standards...
