This notice was published in Japanese. The Japanese text on this page is the regulator’s own, reproduced exactly. The English beneath it is a translation we added to make the notice readable, offered as a help and not as a substitute for the original: where the two differ, the Japanese is what the regulator said. Verify against the official notice before acting on it.
