In May 2024, 19 markets set new monthly records for inbound visitors to Japan; in May 2025, 21 markets did. As cherry blossom season ends and fresh greenery and outdoor activity season begins, May is increasingly establishing itself as a “regional dispersion month” — a period when Western individual travelers and Southeast Asian visitors gravitate toward regional destinations. This article analyzes May 2026 booking trends and examines the regional ADR uplift unfolding in resort prefectures such as Nagano, Yamanashi, and Oita, drawing on publicly available pricing data from MetroEngines Research alongside JTA and JNTO statistics.

May’s “Normalization of Record-Breaking Markets” Signals a Regional Dispersion Season

According to JNTO monthly statistics, inbound visitor arrivals in May 2024 totaled 3,040,100, with 19 markets setting “all-time highs for May.” In May 2025, that number expanded to 21 markets, and arrivals reached 3,693,300 — a 21.5% year-on-year increase. May has thus become a highly seasonally-dispersed month in which not only East Asian markets, but also Western and Southeast Asian markets, simultaneously hit new highs.

Behind this lies a two-stage tourism resource: the latter half of cherry blossom season (late April through early Golden Week), followed by mid-to-late May when fresh greenery and outdoor activities come into season after the petals fall. Temperatures are also mild, and Western individual travelers in particular are increasingly choosing regional resorts for longer stays focused on outdoor activities.

With this structural shift in mind, an overview of May 2026 booking data collected by MetroEngines Research confirms that ADR uplift is clearly underway in three “regional resort prefectures favored by Western individual travelers” — Nagano, Yamanashi, and Oita.

Three Regional Resort Prefectures: Three-Year May ADR Trends

Comparing the May ADR over the past three years for Nagano, Yamanashi, and Oita — three primary destinations for Western individual travelers — all three show a clearly upward trend. Nagano rose from ¥38,000 in May 2024 to ¥44,200 in May 2026, representing a +16.1% increase from 2024 and +12.3% YoY.

Similarly, Yamanashi rose from ¥40,400 to ¥46,200 (+14.2% vs. 2024, +9.2% YoY), and Oita climbed from ¥42,500 to ¥47,700 (+12.4% vs. 2024, +13.3% YoY) — all posting double-digit growth. Yamanashi benefits from Western individual demand around the Fuji Five Lakes and Kawaguchiko area, while Oita’s Beppu and Yufuin onsen resorts are particularly popular among British, Australian, and Southeast Asian visitors.

Of particular note is that for all three prefectures, growth from May 2025 to May 2026 outpaced growth from 2024 to 2025 — even though that earlier period itself saw a surge in record-setting markets. This suggests that 2026 is not simply a yen-weakness uplift, but rather that two years of accumulated awareness of regional resorts, combined with the structural inbound trend from Western and Southeast Asian markets, is converging on May as a regional dispersion month.

Narrowing ADR Gap Between Major Cities and Regional Prefectures in May

Comparing May 2026 ADR across major cities and regional resort prefectures, Nagano, Yamanashi, and Oita all exceed Tokyo (¥37,700) and approach Kyoto (¥45,700). The hotel industry’s traditional formula of “urban = high ADR, regional = low ADR” is visibly inverting during May, the regional dispersion month.

Compared with the major cities of Osaka and Tokyo, ADR levels in the three regional prefectures run 1.5–1.8x higher. Beyond the structural factor that regional areas host many ryokan and onsen resorts with larger room footprints and higher unit prices, this reflects how preference shifts among Western and Southeast Asian visitors are being priced in. The fact that Gifu and Ishikawa have sold-out rates above 20% further corroborates that demand is diffusing across regional resorts more broadly.

Within-Month Dispersion: Mid- and Late-May Hold Up After the Golden Week Peak

Breaking May 2026 in the three regional prefectures into “Golden Week (May 1–7),” “mid-month (May 8–15),” and “late month (May 16–31)” segments, all peak during Golden Week and dip in the mid-to-late period — but the magnitude of the dip is limited. In Oita, for instance, ADR moves from ¥51,400 during Golden Week to ¥47,200 in late May — a difference of only ¥4,200 — confirming stable demand throughout the month.

In Nagano, late May (¥43,000) actually rose above mid-month (¥42,300) following the Golden Week peak of ¥49,800, reflecting Western traveler demand shifting toward the fresh greenery and mountain-climbing season. Yamanashi follows a similar pattern, with mid-to-late May holding at ¥44,000–¥44,800 after the ¥52,800 Golden Week peak. This aligns with the long-stay trend among Western individual travelers in the Fuji Five Lakes and Yatsugatake areas.

Urban areas typically see demand drop sharply after Golden Week, with prices falling significantly through mid-May. In the three regional resort prefectures, however, this “post-Golden Week dip” is muted. In other words, late May (May 16–31) is taking shape as a “second peak” for regional resorts.

Nationality Mix Shift: How Falling Chinese and Rising Western/SE Asian Arrivals Affect Regional ADR

JNTO’s preliminary March 2026 figures show Chinese arrivals down 55.9% YoY (roughly halved), while the U.S. is up 9.7%, Vietnam +43.5%, and the U.K. +20.7% — Western and emerging Southeast Asian markets are posting substantial growth. In March alone, seven markets including the U.S., U.K., and Vietnam set all-time highs.

This shift in nationality composition is a structural tailwind for regional ADR. Chinese travelers historically have a high proportion of group tours and contribute strongly to demand for city hotels in Tokyo and Osaka, whereas Western individual travelers tend to favor regional resorts and onsen ryokan, stay longer, and select higher-priced room types.

In other words, the decline in Chinese visitors exerts downward pressure on Tokyo and Osaka ADR, while the rise in Western and Southeast Asian visitors lifts ADR in the three regional resort prefectures. Indeed, the May 2026 data examined in this article shows that against Tokyo’s +14.2% YoY, Nagano (+12.3%) and Oita (+13.3%) match or exceed it. This is evidence that, rather than the historical pattern of “regional areas catching urban overflow demand,” regional areas are now capturing structural demand of their own.

Implications for Revenue Management

The structural shifts revealed in the three regional prefectures’ data carry important implications for revenue management strategy. First, pricing for the mid-to-late May period (May 8–31) needs to move beyond the conventional “discount immediately after Golden Week” approach. In Nagano, Yamanashi, and Oita, mid-to-late May ADR holds at 80–90% of Golden Week levels, with a clearly upward trend year-on-year. Discounting too early risks leaving money on the table.

Second, Western individual travelers tend to have long booking lead times of 3–6 months, with rates often locked in by January or February rather than just before Golden Week. Strategies targeting late May 2026 should therefore have their pricing direction set by early spring. With sold-out rates currently holding above 10%, an approach that prioritizes maintaining unit pricing over capturing maximum demand is the rational choice.

Third, sold-out rates above 20% are also confirmed in regional prefectures beyond Nagano, Yamanashi, and Oita — including Gifu and Ishikawa — indicating that demand spread is not confined to the three highlighted prefectures. This broader regional diffusion means Western and Southeast Asian travelers are starting to recognize regional resorts across Japan as viable options, rather than concentrating in any single area.

Conclusion: Regional ADR Uplift Continues from After Golden Week into Late May

As confirmed in this article, May has established itself as a “regional dispersion month” — with 17 or more markets setting all-time highs for two consecutive years (2024 and 2025) — and this trend continues in May 2026. In the three prefectures favored by Western individual travelers (Nagano, Yamanashi, and Oita), ADR has risen 14–16% over three years, exceeding Tokyo and approaching Kyoto.

Additionally, within-month decomposition confirms that mid-to-late May holds up firmly after the Golden Week peak, with a “second peak” forming over May 16–31. The shift in nationality mix — falling Chinese visitors and rising Western and Southeast Asian visitors — acts as a structural tailwind for regional resorts.

For hotel operators, the implication is that there is significant scope to revisit the entrenched assumption of “post-Golden Week discounting” for regional resort pricing in late May (especially May 16–31), and instead build pricing strategies premised on Western individual travelers’ long-stay demand. May, as a regional dispersion month, is shifting from a one-shot Golden Week demand event to a realistic strategic objective of maintaining high ADR throughout the entire month.
