Irago Strait

It is a 4.4 km long strait between Cape Irago at the tip of the Atsumi Peninsula in Aichi Prefecture and Kamishima in Mie Prefecture, and forms the mouth of Ise Bay. Commonly known as "Irago Crossing," it is known as a difficult place for ships to navigate due to fast currents and reefs. The width of the passage for large ships is only 1,200 meters between Asahi Sho near Cape Irago and Maruyama Dashi near Kamishima, and navigation is restricted for huge ships over 200 meters in length. In 1973, it was designated as a narrow channel, and there is a ship traffic signal station on the cliff of Cape Irago Lighthouse.

愛知県渥美(あつみ)半島先端の伊良湖岬と、三重県神島(かみしま)との間の4.4キロメートルの海峡で伊勢湾(いせわん)口をなす。通称「伊良湖渡合(どあい)」とよび、潮流が速く暗礁もあって船の難所といわれる。大型船の航行幅は伊良湖岬寄りの朝日礁(しょう)と、神島寄りの丸山出し間のわずか1200メートルで、全長200メートル以上の巨大船は航行が規制される。1973年（昭和48）に狭水道指定航路となり、伊良湖岬灯台の崖(がけ)上に船舶通航信号所がある。
