Welcome to Japan, Taylor Swift Fans. Please Remain Seated as You Cheer.

Taylor mania has landed in Tokyo. But the enthusiasm of some of the Swifties arriving with her has clashed with local sensibilities.

Thousands of visitors from across Asia and beyond have flooded into Japan’s capital as Taylor Swift performs at the Tokyo Dome for four nights this week. The problem, as some domestic concertgoers see it, is that these foreign fans don’t share the rather restrained Japanese approach to taking in a show.

In a post on the platform X, a Japanese holder of a V.I.P. ticket wrote that even paying 130,000 yen — about $870 — and being seated in the third row didn’t guarantee a clear view, given that so many foreign fans had stood up.

“It’s too sad,” the post said. “It’s crazy that, if you follow the rules, you won’t be able to watch it.”

While Japanese are praised abroad for their pristine behavior at soccer matches and other sporting events, their exacting standards at home can make them hostile to visitors. Another post on X, accompanied by a short video of audience members hoisting up their cellphones to capture the scene onstage, complained that “there were many foreigners who couldn’t respect manners.”

The grumbling is in some ways a microcosm of Japan’s mixed reception to the international tourists who have helped restore the country’s economy, the world’s third largest, after the pandemic. More than 25 million people visited Japan last year, according to the Japan National Tourism Organization, nearly 80 percent of the number who visited in 2019.
