Scenery, Information, and Trivia

• From Naruto Interchange until Shishi no Satomiki Bus Stop area is often very congested.
• When entering from Naruto, you pass through the Daidai Kofun Tunnel. When digging this tunnel, they found a "Kofun"(ancient tomb), causing it to have to be modified.
• As you go through the mountains from Itano, after you pass through the longest Osaka Tunnel, you enter Kagawa Prefecture. As you enter Kagawa Prefecture, you become able to see the Inland Sea.
• From Sakaide Junction until Toyohama Service Area is rather flat. After Toyohama, it becomes mountainous again. Once you pass through the mountainous region tunnels, you enter Ehime and Kawanoe Junction.
