Japan’s peak summer rush is in full swing as packed shinkansen trains, sold-out domestic flights, and busy airports show how strong travel demand is in 2025. The surge began in early August and stretches through August 31, with operators urging flexible travel plans to ease pressure.
As of August 9, major shinkansen lines—including Nozomi services to Nagoya, Osaka, and Fukuoka—report full bookings and long lines for unreserved seats. All Nippon Airways (ANA) and Japan Airlines (JAL) say popular routes, especially Tokyo Haneda–Okinawa, are at capacity. Narita Airport reports heavy inbound and outbound flows, reflecting record international interest alongside robust domestic travel.

What’s driving demand now
- Over 70 million people are expected to travel within Japan between July 15 and August 31.
- Japan logged 3,377,800 international visitors in June 2025, up 7.6% from a year earlier — the ninth straight month above 3 million.
- The January–June total reached 21,518,100, the fastest half-year on record.
- Top source markets in June:
- China: 797,900
- South Korea: 729,800
- Taiwan: 585,000
- United States: 345,100
- Outbound Japanese travel is also rising: 1,423,400 residents went overseas in March 2025, up 16.7% year‑on‑year.
Crowds and bottlenecks
Expressways face heavy congestion. Stations are packed with travelers waiting indoors to avoid heat, and station staff are directing foot traffic to prevent bottlenecks.
The June malfunction of the E8-series shinkansen briefly reduced direct trains between Tokyo and Yamagata. Regular service resumed in early August, but the supply of extra trains remains tighter than normal.
Okinawa hotspot
- Okinawa is a focal point: the July opening of the Junglia Okinawa theme park pushed demand higher.
- ANA and JAL flights to the islands are often sold out.
- Hotels in resort areas report high occupancy, and rental cars are scarce during peak weekends.
Voices from the front lines
- JR Central: Bookings are near full across key departures. Travelers are urged to stagger dates and use earlier or later trains when possible. JR Central posts updates on unreserved-seat availability and advises arriving early for crowded departures.
- ANA: Confirms peak flights are full and is monitoring capacity to adjust where aircraft and crew are available.
- Japan National Tourism Organization (JNTO): Reports sustained inbound growth; long-stay and family trips are rising, bringing more first-time visitors into regional areas.
What this means for foreign visitors
If you’re arriving this month, expect crowded hubs and longer lines at major gateways like Narita Airport. Plan extra time for transfers between airport rail links and shinkansen platforms.
Practical steps:
1. Book shinkansen seats as soon as dates are firm. If reserved seats are sold out, unreserved cars may still be an option; arrive early to queue.
2. For domestic flights, consider alternative airports or routes, e.g., Itami or Kobe for Kansai, or later-night departures.
3. Check real-time updates from rail operators before travel, especially in the Tohoku corridor where extra services remain limited.
How families and workers are adjusting
- Families with children are shifting to early morning trains to secure unreserved seats and avoid heat.
- Migrant workers on tight schedules are turning to overnight highway buses when shinkansen and flights are full, despite longer travel times.
- Employers who rely on seasonal staff report delays due to sold-out routes and are offering flexible start dates.
Generational travel patterns
- Gen Z: Seeks “Instagrammable” spots and solo trips, often booking last minute and relying on mobile apps for tickets and hotels.
- Older travelers: Focus on family visits and classic sightseeing loops, increasing demand on core shinkansen corridors and popular domestic flight routes.
Pressure points and solutions
- Capacity: Extra trains are still limited after the E8 restart. Operators say they’ll add capacity where possible, but crew and equipment constraints limit large short-term increases.
- Over-tourism: Analysts recommend dispersal—steer visitors to lesser-visited regions and off-peak times. Regional passes and targeted marketing can help spread demand.
- Heat and safety: Stations remain crowded. Plan water breaks, use shaded waiting areas, and follow staff announcements.
Important: Plan for heat, crowds, and limited last-minute availability on popular routes.
Practical travel tips for August
- Book early and consider off-peak days (Tuesdays and Wednesdays).
- Use alternate routes: for Tohoku, pair limited express trains with local connections when shinkansen seats are gone.
- Check baggage limits and consider delivery services to avoid hauling heavy luggage through crowded stations.
- For unreserved seats, queue at least 30–45 minutes before departure during peak hours.
- Keep backup options like highway buses or late-night flights in mind.
Policy and industry outlook
Authorities and industry groups expect continued high demand through the end of August. Forecasts point to more than 40 million international visitors in 2025 if trends hold.
Planned infrastructure and service improvements:
– Rail signaling upgrades
– Platform crowd control measures
– Airport gate optimization
– Promotion of “smart travel” tools that show live crowding levels and suggest quieter time slots
Immigration checkpoints and entry planning
Arrival halls can fill quickly around midday peak flights. To reduce wait times:
– Complete entry documents in advance.
– Follow arrival hall signs for foreign passports or automated gates if eligible.
– Keep your return/onward ticket and the address of your first stay handy; officers may ask for these.
– Ensure your passport validity and be ready to explain trip purpose and length in simple terms.

Shift to regional travel
Tourism agencies are promoting secondary cities with strong culture, food, and nature to reduce pressure on Tokyo, Kyoto, and Osaka. Deals on local rail and community-run stays help spread spending.
- Analysis by VisaVerge.com suggests steady inbound growth can support rural economies if transport links and clear travel information (especially in English and other major languages) are in place.
What to watch next
- Whether extra shinkansen services expand in late August if crew and equipment free up.
- If airlines open last-minute seats due to schedule changes or larger aircraft swaps.
- How the Okinawa wave continues after Junglia’s opening month and whether demand shifts to shoulder-season dates.
Key reminders for August travelers
- Shinkansen reserved seats and domestic flights are tight; line up early for unreserved options.
- ANA and JAL suggest flexible dates for Okinawa and other popular routes.
- Narita Airport and other hubs remain busy; build buffer time into your plans.
- Stay hydrated, use sun protection, and follow staff instructions in crowded stations.
