Check

When a player's move threatens to capture the opposing king on the next turn, the move is said to give check to the king and the king is said to be in check. If a player's king is in check, that player's responding move must remove the check. Ways to remove a check include moving the king away from the threat, capturing the threatening piece, or placing another interposing piece between the king and the threatening piece.

To announce check in Japanese, one can say ōte (王手), however, this is an influence of international chess and is not required, even as a courtesy. It may be common to announce ōte in beginner matches or for local rules to dictate that you have to announce it. Announcing a check vocally is unheard of in competitive tournaments.
