When I moved to Japan in 1983, not much was computerized and I was able to use my preferred short version of my name--eight letters or five katakana, surname last in both cases--for nearly everything. But over the years more and more places started requiring that names be input into labeled fields, which would reverse the given-name surname order. And many places started to insist on the same name as on my passport--nineteen letters, eleven or twelve katakana, depending on how I wrote it. Many input forms don't allow so many characters, none that I have encountered distinguish first from middle names, and there's usually no way to link that long name to the short name that I have been using for work and in daily life for more than forty years. It's a constant annoyance, not just for me but for other people.
