The decline in the number of Chinese visitors to Japan accelerated in January, fueling the first monthly drop since COVID-19 restrictions were lifted, offering the clearest sign yet of economic fallout from tensions between the countries.

Arrivals from China shrank 61% in January from a year earlier, compared with a 45% decline in December, the Japan National Tourism Organization (JNTO) said Wednesday, citing a shift in the timing of the Lunar New Year holiday and warnings against travel to Japan. The fall dragged down the total number of inbound visitors by 4.9% last month.

The slide was triggered by Prime Minister Sanae Takaichi¡¯s comments late last year that a Chinese invasion of Taiwan could be considered an ¡°existential threat,¡± a characterization that could give Japan legal justification for deploying troops. Beijing subsequently cautioned its citizens against traveling to Japan, resulting in flight cancellations through March 2026.
