What the ministry says is wrong
ショベル・ローダのフロントアンダーガードの取付けボルトにおいて、設計検討が不十分なため、稼働時の外力による捻じれなどにより、ボルトに緩みが生じることがある。そのため、そのままの状態で使用を続けるとボルトが折損し、最悪の場合、フロントアンダーガードが脱落するおそれがある。What is to be done about it
全車両、フロントアンダーガードの締結方法を変更する。また、フロントアンダーガードを対策品に交換する。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 Hitachi: 96 in the register, and 380 Japanese vehicle recall notifications filed in 2025.
