The unfortunate thing in Japan, where I (as well as the author, I believe) reside, is that the government decided to cop out on documentation for foreign residents. Every foreign resident is required to carry an official residence card, which is printed with your name exactly as it appears on your passport. You may think "aren't names in passports written with Latin characters?", and you may also be thinking "isn't the official language of Japan written with non-Latin characters?" Yes, to both.

So basically foreign residents don't have an official Japanese transliteration of their name by default. This is a problem because almost all systems in Japan are made with Japanese people in mind. If you have a middle name then you're basically guaranteed to run into an issue at some point where an application requires your name to match your ID exactly, but the internal system only accepts an input of up to (for example) 16 characters.
