What the ministry says is wrong
タイヤローラーの走行用油圧ポンプにおいて、ポンプ内で使用されているピンリンクを加工する設備の管理が不適切なため、加工不良により強度が不足するものがある。そのため、当該ピンリンクの摩耗が進行し、ポンプ内で脱落することによりピンリンクが他の内部部品を損傷させ、最悪の場合、駐車ブレーキの解除ができなくなり走行不能となるおそれがある。What is to be done about it
全車両、走行用油圧ポンプを良品に交換する。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 201 Japanese vehicle recall notifications filed in 2026.
