May Inbound Visits to Japan: 3.6% Year-on-Year Drop but 19 Markets Hit New May RecordsA · FULL TRANSLATION

【Why Taiwanese Readers Should Care】The Japan National Tourism Organization (JNTO) reported on June 17, 2026, that inbound visitors in May were 355,990 people, a year-over-year decrease of 3.6%. This might seem like a decline but the same data shows record-breaking numbers for South Korea, Taiwan, USA, Malaysia and more, including new highs from Middle East and India. A drop in total numbers with high structural growth is key to understanding Japan's accommodation and consumption market trends – Taiwanese readers doing business or planning trips should focus on 'why the totals are down but who is actually up' rather than being scared by a negative number.

【Decoding the Numbers】May, sandwiched between cherry blossom season and summer break, naturally sees a drop in inbound demand. The base year for May 2025 was particularly high, putting pressure on this year's numbers. Over the past three months: March (361,900), April (369,200 - highest single month for 2026, -5.5%), May (356,000, -3.6%). The continuous decline in these months is mainly due to a higher base year and reduced flights from some markets dragging down the total.

【A Unique Methodological Perspective: Look at Market Diversification】The report's most valuable insight lies in the divergence between total numbers and structural growth. While the overall decrease of 3.6% is driven by a few large markets (affected by high base years or reduced flights), 19 markets set new May records, with Middle East and India hitting single month highs. This indicates that tourist sources are diversifying from concentrated major East Asian countries to multiple points. For businesses, this is more meaningful: as sources become more diversified, the impact of political changes, currency fluctuations, and flight schedules in a single market diminishes. To assess the health of a tourism destination, focus on whether its top five markets' share is increasing or decreasing – a decrease suggests a strengthening foundation.

【Summary of Month-on-Month Changes】This month's increases show clear trends: markets from East Asia like South Korea and Taiwan, Southeast Asia including Malaysia and Singapore, and Europe/Australia such as USA and Germany are all seeing growth driven by holidays and school vacations pushing these markets to new May highs. Markets that were dragged down mainly had reduced flights or particularly high base years last year. In other words, in low-demand months, mature travelers find their own reasons to visit Japan.

【Practical Advice for Taiwanese Readers】First, May is a high CP value window for visiting Japan – avoid peak April and summer vacation periods where accommodation and airfares are cheaper, offering better travel quality. Second, if operating in hospitality or retail, don't interpret single-month year-over-year decreases as decline; focus on whether your primary customer base is within the 19 markets that set new records (Taiwan included), providing a stable baseline for frequent visitors. Third, monitor flight schedules – the reduction in some markets this month directly correlates with reduced flights. Flight increases and reductions are a more reliable leading indicator than weather.

【Next Steps】Watch if summer peak season from July to August can reverse the downturn and narrow or turn positive on year-over-year numbers; track the momentum of the Chinese market's return, which is the largest variable affecting total numbers; observe whether the list of 19 markets with record-breaking figures continues to grow – a longer list suggests a more stable foundation for Japan's tourism business.
