The Tokaido Shinkansen line shows what Japanese engineering can do. The fastest service, called のぞみ (Nozomi), runs at 300 km/h, getting you from Tokyo to Osaka in about 2.5 hours. During testing, these trains have even reached an incredible 443 km/h.

The cost really depends on when and where you're going. Here's what you'll pay for a Tokyo to Osaka trip:

• Bullet train: ¥13,320 to ¥14,570
• Budget flights: From ¥8,200

For longer trips like Tokyo to Sapporo, both options cost around ¥28,000. But here's a tip from my experience - flight prices can drop a lot if you book two months early.

The real cost story isn't just about ticket prices. Bullet train stations sit right in city centers, saving you those pricey airport transfers (usually ¥600 to ¥800). During peak seasons, train prices might go up ¥200-400, but flight prices can skyrocket.

I've found what I call the "4-hour rule" really helpful. If the train journey takes less than 4 hours, the Shinkansen usually saves you money. This factors in all that extra time at airports - security lines, check-in, and getting to and from distant terminals.

The Shinkansen (新幹線) network connects Japan's major cities across Honshu island. These sleek trains zip between destinations at speeds reaching 320 km/h. After countless trips on these trains, I can tell you they're often your best choice for city-to-city travel.

The Tokaido Shinkansen (東海道新幹線) really shines for shorter trips. This line connects Japan's biggest cities - Tokyo, Nagoya, and Osaka. You'll skip all those time-eating airport procedures if your journey is under four hours.

Quick journey times I've experienced:

• Tokyo to Kyoto: 2 hours 15 minutes
• Tokyo to Nagoya: 2 hours
• Osaka to Fukuoka: 2.5 hours

Unlike airports stuck out in the suburbs, Shinkansen stations sit right in the heart of each city. Trains leave every few minutes, perfect for both tourists and business folks rushing to meetings.

These stations have grown into much more than just train stops. Take Tokyo Station (東京駅) - it's practically a small city underground. You'll find:

• Shopping malls with local specialties
• Restaurant streets serving regional dishes
• Business centers and meeting spaces

The impact on local economies has been huge. When the Shinkansen reached Kagoshima in 2011, the area saw economic growth exceeding ¥46 billion.

Sometimes planes beat bullet trains in Japan. After years of traveling across the country, I've learned exactly when to skip the rails and take to the skies. Here's what experience has taught me - if your trip is over 450km or would take more than 3.5 hours by train, flying usually makes more sense.

Flying really shines for longer trips. Take the Tokyo to Kagoshima route - flights start at ¥13,800, plus about ¥1,600 for getting to and from airports.

Best routes for flying:

• Tokyo to Sapporo (札幌): Just 1.5 hours in the air
• Osaka to Kagoshima (鹿児島): 2.5 hours total
• Tokyo to Fukuoka (福岡): 2-hour flight

Here's a money-saving tip I've learned - book two months ahead for special deals. Budget airlines like Peach and Jetstar often offer cross-country flights cheaper than a nice dinner out.

Japan's island layout means sometimes you have to fly. Places like Shikoku (四国) don't have bullet train service at all.

Fukuoka Airport (福岡空港) surprised me with its convenience - it's just one subway stop from Hakata station. This makes flying to Kyushu much more appealing than I first thought.

For Hokkaido trips, planes are your best friend until they finish building the Sapporo Shinkansen extension. The airlines make these multi-city bookings surprisingly simple.

The scheduled times you see online don't tell the whole story. Research shows people spend about 157 minutes at airports compared to just 32 minutes at railway stations. Let me break down what this means for popular routes based on my frequent travels across Japan.

Tokyo to Kyoto is the most traveled route for tourists in Japan. The のぞみ (Nozomi) bullet train covers this route in 2 hours 15 minutes, cruising at 300 km/h. Flying might seem faster at 90 minutes in the air, but you'll spend 2 more hours dealing with airport hassles. Take the bullet train and you'll find yourself in Japan's cultural heart in no time!

Getting to Hokkaido shows different timing patterns:

• Flight time: 1 hour 32 minutes
• Total time with airport procedures: 4 hours
• Bullet train to Hokkaido: 4 hours (only reaches Hakodate for now)

The Sanyo Shinkansen (山陽新幹線) really shines on this route. Setting off from Osaka you'll spend 2 hours 20 minutes on the train, with consistent service throughout the day.

Flying between these cities looks like this:

• Pure flight time: 70-75 minutes
• Door-to-door journey: 2 hours 30 minutes
  

The Japan Rail Pass changed a lot in October 2023. Here's what you'll pay now:

• 7 days: ¥50,000
• 14 days: ¥80,000
• 21 days: ¥100,000

Rail pass holders get some nice perks - like free seat reservations that normally cost ¥1,000 per ticket. A single Tokyo-Kyoto round trip costs about ¥26,160, so the pass can really save money if you're visiting multiple cities.
