What is the biggest deficit industry in Japanese tourism?

Tourism is the first deficit industry in Japan's service trade. Both China and Japan are deficit countries in service trade, and the international competitiveness of service trade is not as strong as that of goods trade. Moreover, both countries develop trade in goods first and then trade in services, and the competitiveness index of service trade in both countries is negative. But on the whole, Japan's service trade is more competitive than China's, so it is of great significance to learn from Japan's service trade development strategy for the development of China's service trade.
