Obon Holiday Return Rush Begins in Japan, Highway Traffic Peaks

Japan's Obon holiday return rush has officially begun, as millions of travelers make their way back to major cities after visiting their hometowns during the traditional summer holiday period.

Today has been identified as the peak day for highway congestion in the 'up' direction, referring to traffic flowing toward Tokyo and other large urban centers.

The Kanetsu Expressway, a key route linking rural regions to the capital, has seen a traffic jam stretching as long as 35 kilometers, according to reports.

Similar delays have been reported on other highways throughout the country as families conclude their holiday visits and return to their daily routines.

While road traffic has reached its highest point today, other forms of transportation are expected to peak slightly later in the week.

Bullet trains, or Shinkansen, along with domestic and international flights, are forecast to experience their busiest period starting from August 15, as travelers stagger their return journeys across different transport methods and days.

This annual pattern reflects the scale of movement during Obon, one of Japan's most significant holiday periods, during which many people travel to ancestral hometowns to honor family traditions.

Because the holiday falls within a relatively short and fixed window, the return journey tends to create a concentrated surge in demand across all major transport networks, rather than a gradual spread of travelers.

Highways typically see congestion first, as many families choose to drive back immediately after the holiday ends, while train and flight bookings often peak a day or two later, as travelers with reserved seats plan their return around specific dates.

Transport authorities and travel companies routinely issue advisories ahead of these peak travel dates, encouraging passengers to consider alternative schedules where possible.

However, given the fixed nature of the Obon calendar, significant congestion across highways, railways and airports remains largely unavoidable each year, making this seasonal rush a familiar challenge for Japan's transportation infrastructure.
