What the ministry says is wrong
二列目座席シートベルト非装着時警報装置において、バックル電気配線の配索検討が不十分なため、シートベルト脱着時に当該配線に繰返し負荷がかかり断線することがある。そのため、シートベルト装着状態が正しく警報されないおそれがある。What is to be done about it
該当車両において、（１）二列目左側座席バックルの電気配線の配索を点検し、異常がある場合はバックルを新品に交換する。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 Toyota: 594 in the register, and 201 Japanese vehicle recall notifications filed in 2026.
