Trains, planes and roads were crowded nationwide Sunday, the last day of this year's holiday-studded Golden Week period, as holidaymakers returned home from their destinations.
Some of the Shinkansen bullet trains and Tokaido line trains bound for Tokyo ran at more than 100 percent capacity in their non-reserved sections, according to Japan Railway companies.
The Nozomi 18 service from Hakata, Fukuoka Prefecture, and Tsubasa 114 service from Shinjo, Yamagata Prefecture, both to Tokyo, carried 50 percent more passengers than their capacity, the JR companies said.
Tokyo-bound lanes on major highways saw some traffic jams but not as heavy as in previous years as many people apparently took holidays at different periods, the Japan Road Traffic Information Center said.
Domestic flights to Tokyo's Haneda airport were almost fully booked, airline companies said.
