What the ministry says is wrong

 加速装置において、スロットルケーブルの防水構造が不適切なため、雨天時の走行等に より、後輪タイヤの跳ね上げた水が当該ケーブル内部に浸入することがある。そのため、 低温時に当該ケーブル内部に浸入した水が凍結し、最悪の場合、アクセルグリップが戻ら なくなり、エンジンの回転が下がらなくなるおそれがある。

What is to be done about it

全車両、スロットルケーブルを対策品と交換する。

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.

Source: Ministry of Land, Infrastructure, Transport and Tourism website (出典:国土交通省ウェブサイト), used under the Public Data License 1.0. This site gathered the record, grouped it by notification number and set it in English around the ministry's own words; the notice itself is unaltered. CarsMultiverse is not the ministry and not a safety authority. To act on this notice, use the ministry's own document.

The Japanese register on this site

ヤマハ elsewhere in this register

ヤマハ is named on 181 notices in the copy of MLIT’s register held here, of which these are the nearest to this one in time.

The same part: アクセル

115 notices in this register name アクセル. A defect that keeps returning under one heading is worth reading as a group rather than one notice at a time.

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 Yamaha: 186 in the register, and 511 Japanese vehicle recall notifications filed in 2004.
