Why Japan Is Spending $85 Billion to Build the World’s Fastest Train

Welcome to Billionaire lnvestment –Why would Japan spend $85 billion to build the world’s fastest train, when it already has the legendary Shinkansen?
In this video, we go inside Japan’s most ambitious infrastructure gamble: the Chuo Shinkansen Maglev, a 500 km/h (311 mph) superconducting train running mostly deep underground between Tokyo, Nagoya, and Osaka.
This isn’t just about speed.
It’s about economic survival, national strategy, and future-proofing one of the world’s most important transport corridors.
In this video, you’ll discover:
Why Japan chose to build a brand-new maglev line instead of upgrading existing rail
How 500 km/h underground travel changes the economics of Tokyo–Nagoya–Osaka
Why 86% of the route is in tunnels, and why that drives costs sky-high
How this project acts as a backup lifeline for Japan’s aging Tokaido Shinkansen
Who actually benefits from the Chuo Shinkansen — and who pays the price
Whether this is a visionary investment or one of the most expensive transport bets in history
With costs rising, timelines slipping, and public pressure mounting, Japan’s maglev project has become a real-world stress test for modern mega-infrastructure:
Can speed still buy economic advantage in the 21st century?
Or is this the limit of what even a highly organized nation can pull off?
If you’re interested in megaprojects, high-speed rail, infrastructure economics, future cities, and how money quietly reshapes geography, this video breaks it all down — clearly, critically, and without hype.
Watch until the end to see why Japan believes this train could redefine the future of ground transportation.
