Do I need a round-trip (return) flight ticket to apply for my visa to Japan?
It depends on the nationality. While some nationalities need to hand in a round trip booking confirmation when applying for the visa, most nationalities don't, but only a one-way ticket to Japan is required (or not even required at all for some nationalities such as UK citizens). However, in this case, you need to prove higher financial means in your bank account compared to when having a round trip booking. You can find those details on the websites of the Japanese embassies in your country of residence.
