Around a quarter are visiting the Kanto region, which includes Tokyo, making it the most popular destination. The Kinki region, which includes Kyoto and Osaka, followed at 16%. The Tokai region, which includes Nagoya, came in third at 12%. More people also appear to be planning longer trips of three to six nights than a year earlier, according to JTB's forecast, which is based on surveys, spending trends and airline reservations. [...] Meanwhile, international travel has been slow to recover because of expensive airfares and a weak yen. Around 580,000 people will travel abroad during the upcoming holidays, according to JTB -- up about 160% on the year but still only 70% or so of the pre-pandemic figure. A lack of airline capacity is another factor. All Nippon Airways is operating 1,381 international flights around the new year, while Japan Airlines is operating 1,363 -- the equivalent of 65% and 78% of the pre-pandemic figure.
