noun
A voting method where the voter's identity is not recorded on the ballot, ensuring anonymity. Used in elections and formal decision-making.

The union officer election was conducted by secret ballot.
記名投票 is an open ballot where the voter's name is recorded, contrasting with 無記名投票's anonymity.
Compound of 無 (mu, 'without'), 記名 (kimei, 'signature/name recording'), and 投票 (tōhyō, 'vote'). The term is a direct translation of the Western concept of secret ballot, adopted during Japan's modernization.
