In Japan, proposals are usually private and can be very direct or more indirect, but the basic idea is still the same: one person asks the other to marry them. A common phrase is “Will you marry me?” and many couples also talk seriously about marriage before the formal proposal.

For the surname part, yes — under Japan’s current law, married couples must choose one family name, and in practice the wife takes the husband’s surname in most cases. Reports cited by major outlets say this happens for more than 95% of married women, though a husband can technically take the wife’s name instead.

How proposals work

Japanese proposals often happen after the couple has already discussed marriage, rather than as a total surprise. Family approval can also matter, especially in more traditional situations, and some couples still treat meeting the parents as an important step before proposing.

Common proposal styles include:

  • A straightforward “Will you marry me?”
  • A more indirect romantic line.
  • A proposal tied to dinner, a trip, or a special date.

Surname rule

Japan’s civil code requires married couples to use the same surname, making it unusual internationally. In practice, social convention strongly favors the wife adopting the husband’s surname, even though the law does not require that specific direction.

That means the answer is:

  • Proposals: usually personal, sometimes traditional, often preceded by relationship talks.
  • Surname: yes, usually the wife takes the husband’s surname.

Bottom line

So the short version is: Japanese marriage proposals can be as direct as “Will you marry me?”, and after marriage the couple must share one surname, with the wife usually taking the husband’s name.

TL;DR: In Japan, proposals are often preceded by discussion, and married couples must use one surname; most wives take the husband’s surname.
