3 Tunnels Garnering Attention from Tourists

Today is a collection of 3 unique tunnels. Don’t look down on them because they’re called tunnels! You’ll realize the mistake you’ve made after reading. These tunnels are worthy as tourist attractions and range from those made from the latest technology to strange ones in the country. I’ll be blown away if you’ve ever heard of the third tunnel!


Kanmon Tunnel

The Kanmon Tunnel connects Yamaguchi prefecture with Fukuoka by going under the Kanmon Straits. (It was completed in 1958. It’s 780m long and took 21 years to finish.) Now this tunnel is popular as a tourist attraction among visitors. The reason is because it’s a walkable undersea tunnel—a real rarity. And many people are impressed that we had the technology to build an undersea tunnel over 50 years ago.

The footpath here is 4m wide and 60m underground. There’s also a two-lane road for cars on the upper level. Pedestrians can cross for free and have a nice 13 min walk under the sea!

And here’s the borderline between Yamaguchi and Fukuoka. It’s unusual to have a border under the sea and it’s a place for commemorative photos regardless of your nationality.

<Tip 1>
Strike a pose and snap a photo! And on the other side you can get a commemorative stamp to complete the memory!

Tokyo Bay Aqua-Line

The Tokyo Bay Aqualine is a highway that crosses the Tokyo Bay, connecting Kawasaki, Kanagawa prefecture and Kisarazu, Chiba. As you see in the diagram, cars can drive undersea!

In the middle there’s the Umihotaru PA, reachable from any direction and arranged to allow for U-turns. There’s many who pay just a one-way fee, drive, and then spend their time at this Umihotaru. As you can see from the pictures, it’s quite pretty and a great date spot.

This is called the Cutter Face. This 14.14m blade was actually used during construction. This is another definite must-see.

<Tip 2>
For temporary visitors coming from overseas, reach your destination and also see the undersea tunnel by taking a highway bus that goes through the Aqualine from Haneda Airport or Tokyo Station!

Doai Station

This train station, called the “mole station,” is in Gunma prefecture. It’s named such for its up and down platforms being 70.7m different in height. So if you need to get to the other side of the station, it takes about a 10 minute walk. The picture is of the down platform (underground).


To go to the up platform, you need to climb these 462 stairs—a length of 338m. (And to reach the surface is 24 steps more, for a total of 486.)

Once you’ve actually gotten above ground, you’ll find Doai Station. The underground, above ground and moles are deceiving but it’s actually a mountainous region so it’s high in elevation. (The down platform is 585m above sealevel, the up platform is 653.7m.)

Doai Station is an unmanned, rural train station that seems to only be used by climbers for Mt. Tanigawa but it’s gathering notoriety as a tourist attraction. This unusual station was picked as a Top 100 Kanto Region Station.

<Tip 3>
Don’t be deceived by it’s mole nickname. It’s high in elevation so it feels cool even in summer. Be sure to pack long sleeves!

We’re sure that most people have never heard of our third recommendation, Doai Station!
