First, let's take a trip to the aquarium!
Our journey begins at Wakayamashi Station. From here, we'll take the train toward Wakayama Port!
Today, Wakayama Port Station is the final stop. Under this proposal, the line would be extended to reach the aquarium.
The new railway would travel underground.
A gateway to historic shrines, temples, and scenic coastal views. One more stop to go!
About 75 minutes from Namba and around 50 minutes from Kansai Airport. The aquarium is just ahead!
A uniquely Japanese-style aquarium overlooking beautiful Wakaura Bay. We've arrived!
This proposal extends the Nankai Wakayamako Line southward from Wakayama Port Station.
Two new stations would be added: Wakaura Station and Marina City Station.
The extension would provide direct access between Marina City, Namba, and Kansai International Airport, while also improving access to the historic Wakaura area.
Several alternative routes were considered, but this option was found to be the most practical in terms of construction, urban impact, and accessibility.
Now, let's take a glimpse into Wakayama's future!

Wakayama could become a much more accessible destination within the Kansai region.
There are so many more visitors now.
It's hard to believe this area used to be so quiet.
Economic decline may not disappear overnight—but this could be a meaningful first step.
