The image of “Niseko = winter” has been firmly established for years. However, observing accommodation booking data for July-August 2026 reveals that selling prices in Kutchan Town have increased by more than 20% year-on-year, indicating that summer Niseko is quietly transforming into a viable investment target. This article quantitatively examines whether the green season is shifting from “winter’s leftover” to “an independent investment target,” using monthly ADR data for the three areas of Kutchan Town (倶知安町), Niseko Town (ニセコ町), and Rankoshi Town (蘭越町) from 2024 to 2026, along with price tier growth rates and actual price distributions of major properties.

Why Discuss Niseko’s Green Season Now?

Niseko’s winter ADR has consistently tracked far above the Hokkaido average. According to MetroEngines Research data, Kutchan Town’s average room rate for January-February 2026 reached approximately ¥123,000, an increase of more than 20% from the prior-year average of ¥102,000. Meanwhile, July-August ADR — historically treated as the “off-season” — softened to -9.9% YoY in 2025 in Kutchan Town, but at the 2026 booking stage has rebounded to the ¥58,000 range, reaching its highest level in the past two years.

This summer rebound is difficult to explain by seasonality alone. When examining Hokkaido-wide monthly ADR trends, summer growth rates are not as large as those seen in the three Niseko towns. In other words, the green season upside is a Niseko-specific phenomenon, suggesting some structural change is occurring on the demand side.

Additionally, in the first half of fiscal 2025, Kutchan Town’s actual visitor numbers showed a strong +3.9% YoY, with total overnight stays up +25.1%, while Niseko Town moved in the opposite direction at -12.4% and -24.0% respectively (Source: Hokkaido Shimbun, December 2025). Even within the same Niseko area, investment direction is beginning to diverge by town. This article tracks the underlying drivers quantitatively through price data.

Monthly Green Season ADR Trends: 2024-2026

First, we line up monthly ADR for the green season (June-September) across the three towns. Kutchan Town’s ADR was stable in the ¥53,000 range in 2024, fell to the ¥44,000-¥48,000 range in 2025, and rapidly rebounded to ¥54,000-¥60,000 at the 2026 booking stage. Niseko Town and Rankoshi Town show more gradual but consistent upward trends in 2026.

Kutchan Town deserves attention. After ADR declined once in summer 2025, 2026 shows a sharp recovery exceeding +22% YoY. This is consistent with the scenario that “after demand thinned during the 2025 adjustment phase, travel appetite has returned, led by affluent travelers.” Meanwhile, Niseko Town’s ADR has remained nearly flat in the low ¥50,000 range from 2024 to 2026, with small price fluctuations. Rankoshi Town, despite its lower absolute level, broke into the ¥40,000 range in 2026, recording the most pronounced step-up among the three towns.

Summer-to-Winter Price Multiple: How Much Does “Winter Bias” Remain?

The core of Niseko’s revenue structure is “the gap between winter peak and summer trough.” In Kutchan Town, January-February 2026 ADR reaches ¥123,000 while July-August stands at ¥58,000 — a multiple of approximately 2.11x. Compared with Western ski resorts (such as Aspen in the US or Zermatt in Switzerland), Niseko’s bias toward winter remains extremely strong. However, this multiple has been gradually shrinking since 2025.

Kutchan Town’s winter/summer ADR multiple expanded from 1.47x in 2024 to 2.14x in 2025, then declined slightly to 2.11x at the 2026 booking stage. This “slight decline” means that even though winter ADR grew further, summer ADR rose at a faster pace than winter. In other words, Kutchan Town appears to be entering a phase where summer is starting to catch up. Niseko Town, by contrast, has consistently strengthened its winter bias from 1.25x → 1.56x → 1.76x, presenting a contrasting picture.

Green Season Growth Rate by Price Tier: Testing the Affluent Shift Hypothesis

This is the heart of our analysis. We classified properties located in the three Niseko towns into four tiers based on their summer 2025 ADR levels, and measured how much the same property cohort raised ADR at the 2026 summer booking stage. The hypothesis: if Western affluent travelers are flowing into the green season, growth rates in the upper tiers (high-class, upper-mid) should significantly exceed the overall average.

Source: MetroEngines Research, compiled by HotelBank Editorial Team (N = 33 economy properties, 37 midscale, 15 upper-mid, 7 high-class — all properties with 30+ booking records in both summer 2025 and summer 2026)

The results partially confirm and partially contradict the hypothesis. The upper-mid class (¥60,000-¥100,000) showed an extremely high growth rate of +31.6% YoY, and the high-class tier (¥100,000+) was also robust at +21.6%. In these tiers, average ADR rose from ¥74,000 in 2025 to ¥97,500, and from ¥152,000 to ¥185,000 in the high-class tier.

However, what was unexpected is that the “midscale (¥30,000-¥60,000)” tier showed the largest growth rate of all tiers at +40.1%. This suggests that, in addition to the affluent shift, a broader segment of inbound travelers is beginning to discover Niseko as a green season option. The economy class (under ¥30,000) also rose +22.1%, indicating that demand is broadening across the entire summer Niseko market.

In other words, the green season’s growth is not a “wealthy travelers only” story. While the upper-mid to high-class tiers are leading, the midprice band is simultaneously gaining depth. From an investor’s perspective, it is natural to view this as creating opportunities for both high-end development and repositioning of midprice hotels in parallel.

Actual Price Distribution at Three Major Properties: Hilton, Panorama, Sansui Niseko

Macro aggregates can hide certain realities. When examining price distributions at the individual property level, we see that the green season’s revenue structure is not uniform. Here we focus on three representative property types in the area and compare ADR trends between summer and winter.

Hilton Niseko Village (506 rooms) shows a roughly 4x difference between summer ADR of ¥28,600 and winter ADR of ¥115,400, displaying the typical “winter-biased resort” revenue structure. For 500-room-class operations, capturing MICE and group travelers to support summer occupancy becomes a critical strategy.

On the other hand, luxury chalets like Panorama Niseko (12 rooms) maintain ADR exceeding ¥200,000 even in summer, with the price tier itself locked into the ultra-high-end segment. Sansui Niseko (53 rooms) sits in a midsize high-class position with summer at ¥60,000-¥80,000 and winter at the ¥230,000 level — although seasonal differences exist, summer remains in a price band that is reasonably monetizable.

What these three typical examples reveal is that Niseko’s “winter bias” varies dramatically in structure depending on property scale and price tier. When investors conduct due diligence, they need to consider not only the simple “winter ADR” but also the absolute summer level and occupancy outlook in tandem.

2026 Summer Booking YoY Growth Rates: How to Read the Future

To conclude this analysis, we summarize the ADR growth rates at the 2026 summer booking stage for each of the three towns. YoY results are: Kutchan Town +22.2%, Niseko Town +3.4%, and Rankoshi Town +17.0%. Kutchan Town and Rankoshi Town both show double-digit growth, suggesting that the “lead actor” of summer Niseko is gradually shifting.

For regional revitalization stakeholders, these numbers carry important implications. Kutchan Town is the lead area for winter, but its summer selling price growth is also the largest, evidence that visitor inflows and improvements in stay value are advancing in parallel. Rankoshi Town has traditionally been known as a hot spring area, but its ADR has lifted into the ¥40,000 range, suggesting that the perception of “an affordable area on the edge of the Niseko region” is changing.

Meanwhile, Niseko Town (around Annupuri) shows steady but modest summer ADR growth of +3.4%, consistent with the -24.0% drop in total overnight stays in the first half of 2025. In Niseko Town, the summer guest profile and property mix differ from Kutchan Town — midsize properties oriented to families and individual travelers dominate — which may be suppressing upward price pressure.

Implications for Investors and Regional Revitalization Stakeholders

The investment-decision framework derived from the data can be organized as follows.

Kutchan Town is an area lined with high-end developments such as Hoshino Resorts’ “Hoshinoya Hutte Niseko” (tentative name, scheduled to open in fiscal 2029), and is in a phase where prices continue rising in both winter and summer. For investors, “property design enabling year-round operation” will determine success or failure. Niseko Town, by contrast, has a strong traditional family-resort character and limited room for summer price appreciation, making repositioning of existing properties (uplift to higher-rate segments, or capturing training-camp/MICE demand) a critical theme.

For Rankoshi Town, although the absolute level is low, growth is conspicuous, and there is significant upgrade potential for small-to-midsize properties centered on hot spring inns. From a regional revitalization perspective, Rankoshi Town’s role as a spillover area for tourism demand concentrated in Kutchan Town and Niseko Town may grow in importance going forward.

Summary

This article quantitatively examined whether Niseko’s green season is transforming into an investment target, using monthly ADR data for Kutchan Town, Niseko Town, and Rankoshi Town from 2024 to 2026. The findings confirm three points: (1) Kutchan Town’s summer ADR shows a sharp rebound of +22% YoY at the 2026 booking stage; (2) Growth rates of upper-mid and high-class properties stand out; (3) However, midscale (¥30,000-¥60,000 tier) recorded the largest growth at +40%, making clear that this is not a story about wealthy travelers alone.

Niseko’s winter still boasts world-class ADR levels, but summer is shifting from “winter’s leftover” into a season with independent revenue opportunities. The winter/summer ADR multiple still hovers around 2x, but if green season uplift continues, this gap should gradually narrow. For investors and regional revitalization stakeholders, Niseko’s green season is a target whose narrative may be substantially rewritten over the next several years.
