Mitsumasa Etou, a representative of the research site Economic Effects NET and a lecturer at Tokyo City University, predicted that The Eras Tour would inject around $229 million (£174m) into the Japanese economy.
He also estimated that Tokyo's revenues would increase by about 25% each night of the tour, with both international and Japanese fans spending money in restaurants, shops, and on sightseeing near the venue.
Etou described the tour as Japan's biggest-ever musical event in terms of predicted economic impact, surpassing Fuji Rock, one of Japan's largest music festivals, which generated around $134 million (£102m) in 2023.
