What the ministry says is wrong
全方位安全運転支援システム装備車において、ドライバモニタカメラ制御コンピュータの制御プログラムが不適切なため、外部診断機でのプログラム更新または故障コードクリア後に演算処理が終了しないことがある。そのため、過大な待機電流が流れ続け、車両を使用せずに長期間駐車した場合、バッテリが上がり、パワーシステムが起動できなくなるおそれがある。なお、外部診断機でのプログラム更新後は、パワーシステム起動時にドライバモニタカメラが起動せず、システム故障時にブレーキ警告灯等が不点灯となり、保安基準に適合しない。What is to be done about it
全車両、ドライバモニタカメラ制御コンピュータを対策プログラムへ書き換える。The two passages above are quoted in Japanese because that is the language the ministry published them in. This site keeps the wording a register had when it was read, and does not translate a safety notice.

Reading this against the source
This page is what MLIT published in the recall notices it publishes, kept as it was read. The authority publishes only its current wording; if a notice is rewritten, the earlier version disappears there and is kept here. The whole register is at /japan, and how the reading is done is set out in the method.
This register keeps an index of its own for every maker and every year it holds: Japanese recalls on a Honda: 465 in the register, and 380 Japanese vehicle recall notifications filed in 2025.
