The 80th National Sports Games, “Ao no Kirameki Aomori Kokuspo,” opened on Saturday, October 10, 2026 with the general opening ceremony at the New Aomori Prefecture General Sports Park in Aomori City, and the main session runs through the general closing ceremony on Tuesday, October 20. The National Sports Games for Persons with Disabilities (the “Disability Games” below) follow for four days, from Friday, October 23 to Monday, October 26. We have already published analyses of inventory and prices by municipality within Aomori — one showing just 18 rooms left on October 10 against roughly 1,500 on weekdays, and another showing 27 Aomori properties with zero rooms left 45 days out even on weekdays — so this article widens the scope to three prefectures, Aomori, Iwate and Akita, and narrows the metric to “the gap in inventory sell-through across prefectural borders.” We do not repeat the municipal price tiers within Aomori here.

The question is simple: how much of the lodging demand that Aomori cannot absorb is showing up in Iwate and Akita? We re-pulled MetroEngines Research booking curves on October 10, 2026 (last observation as of October 9) and lined up the inventory sell-through rate, rooms left and average listed price of remaining rooms for the three prefectures for every stay date from October 1 to 31. We also set Miyagi, Yamagata and Fukushima as a control group to separate out factors unrelated to the Games, such as the three-day weekend and the autumn foliage season. The conclusion up front: judging from the interim picture as of October 10, spillover from Aomori to its neighbors has been modest — “simultaneously full on the opening three-day weekend” and “a few points of uplift in neighboring prefectures on session weekdays” — and Iwate and Akita still hold a combined buffer of around 2,000 rooms on session weekdays.

Games Schedule — Demand Peaks at the Start of the Session and the Disability Games Weekend

First, the schedule from primary sources. According to the official Games website, the pre-session events were held in Phase I from Thursday, September 3 to Sunday, September 13 and Phase II from Friday, October 2 to Friday, October 9; the main session runs from Saturday, October 10 to Tuesday, October 20, with both the general opening and closing ceremonies held at the New Aomori Prefecture General Sports Park. The Disability Games run from Friday, October 23 to Monday, October 26. What matters for the lodging market is that the opening ceremony on October 10 falls on the first day of a three-day weekend that includes Sports Day, when leisure demand unrelated to the Games also rises across all of Tohoku. Reading October 10 alone as “Aomori demand overflowing into neighboring prefectures” would therefore be premature; this article compares at the same lead time and alongside control prefectures.

Aomori’s Inventory Progress — 18 Rooms Left for Oct 10 from 45 Days Out, 94–97% on Session Weekdays

The table below sets the latest observations for key stay dates against ordinary days for the 87 properties / 7,110 rooms covered in Aomori Prefecture. Saturday, October 10 stood at 99.7% sell-through with 18 rooms left at LT45, meaning allotments were nearly exhausted more than 45 days before the stay date, and even at LT1 just before arrival only 66 rooms remained at an average listed price of ¥48,700. By contrast, Tuesday, October 6, a pre-session weekday, was at 94.7% with 376 rooms left at ¥25,600, and Tuesday, October 13, a session weekday, was at 94.7% with 380 rooms left at ¥32,200 as of LT4 — numerically not much different from before the session. Aomori’s demand peaks do not spread evenly across the whole session; they stand at the opening ceremony weekend and the Disability Games weekend.

Note that for stay dates from October 10 onward, the observed LT lengthens by one day per date. Tuesday, October 20, the day of the closing ceremony, has the most slack of the session at 88.1% with 844 rooms left as of LT11; this is because much of the delegations head home on the closing day, and even at the same LT22 it is lower, at 83.4% versus 92.7% for October 13. It is reasonable to read the “exit” of the session as less tight than its entrance.

Same-Day Comparison with Iwate and Akita — Spillover Hidden by the Long Weekend, a Few Points of Uplift on Weekdays

So how did the neighboring prefectures move? In the final observation for the same Saturday, October 10, Iwate was at 99.4% with 65 rooms left and Akita at 98.9% with 53 rooms left — close to full, like Aomori. However, the control group was at the same level, with Miyagi at 97.6%, Yamagata at 99.5% and Fukushima at 99.1%, so it is reasonable to interpret that day’s sellout as the result of leisure demand on the first day of the three-day weekend filling all of Tohoku rather than of the Games. The shape of the curves differs. Whereas Aomori’s October 10 was already at 99.7% at LT45, Iwate started from 83.0% at LT45 (1,734 rooms left) and Akita from 75.2% (1,204 rooms left), and both used up nearly all remaining rooms over the 45 days. Inventory in the neighboring prefectures was absorbed at a slower tempo than in Aomori, but absorbed to the end.

To strip out the effect of the three-day weekend, the next chart aligns every stay date at the same stage, 22 days before the stay date (LT22), and lines up six prefectures. Aomori reached an average of 91.9% at LT22 on main-session weekdays (Oct 13–16 and 19–20), up 4.3 points from 87.6% on pre-session Phase II weekdays. Iwate rose 3.3 points from 67.8% to 71.1%, and Akita rose 3.7 points from 66.0% to 69.7%. Meanwhile, in the control group, Miyagi fell 5.1 points from 71.8% to 66.7%, Yamagata fell 1.2 points from 70.0% to 68.8%, and Fukushima was nearly flat, from 64.2% to 64.4%. The difference in direction — the two neighboring prefectures moving up from their own pre-session levels while the control prefectures in the same Tohoku region moved down — suggests that spillover from Aomori to Iwate and Akita does exist. But its size is 3–4 points at the same stage and 3–9 points relative to the control prefectures, not a scale at which one could say that “overflow demand filled the neighboring prefectures.”

Isolating Saturdays makes the picture even clearer. At LT22, Aomori went from 88.3% on Oct 3 to 99.7% on Oct 10, 98.8% on Oct 17 and 99.5% on Oct 24, pinned at around 99% on all three Saturdays during the Games period. By contrast, Iwate was at 88.3% on Oct 3, 94.6% on Oct 10, 84.3% on Oct 17 and 87.3% on Oct 24, and Akita at 89.1%, 87.6%, 77.6% and 84.1%. Miyagi, Yamagata and Fukushima were at 78.8%, 79.7% and 77.5% respectively on Oct 17, almost no different from Iwate and Akita on that date. In other words, even on Saturdays when Aomori was full, Saturdays in the neighboring prefectures were not observed filling beyond an ordinary Saturday, at least at the 22-days-out stage.

The gap in price is larger than the gap in sell-through. Looking at the average listed price of remaining rooms for Saturday, October 17 during the session, Aomori was at ¥43,000 as of LT8, Iwate at ¥27,900 and Akita at ¥28,600, making Aomori around ¥15,000 higher than its neighbors. For Saturday, October 24 of the Disability Games, the same gap holds as of LT15: Aomori ¥48,000 versus Iwate ¥31,200 and Akita ¥28,100. On session weekdays October 13–16 as well, Aomori was at ¥32,200–38,300 against ¥20,900–22,100 in Iwate and ¥22,900–26,700 in Akita. The average listed price of remaining rooms is a metric influenced by unsold higher-priced rooms, but the fact that rooms more than ¥10,000 cheaper remain by the thousand in neighboring prefectures on the same dates means that properties within reach of the venues by secondary transport still have room to win cross-border demand on price.

Host-Municipality Room Stock and the Three-Prefecture Total — How to Read the Depth of the Buffer

Next, the depth on the supply side. Tallying by municipality the rooms of properties whose operation MetroEngines Research can confirm, Aomori Prefecture has 239 properties and 14,426 rooms, of which Aomori City, where the general opening ceremony is held, has 4,064 rooms, Hachinohe City 3,107 and Hirosaki City 2,141 — 9,312 rooms across the three cities (about 65% of the prefecture). Towada City with 1,225 rooms, Misawa City with 863 and Mutsu City with 760 follow. Iwate Prefecture has 16,320 rooms, with 4,563 in Morioka City, and Akita Prefecture has 10,839 rooms, with 4,081 in Akita City. The combined room stock of the three prefectures is 41,585 rooms, 2.9 times that of Aomori Prefecture alone.

One caveat here: the total room stock and the booking-curve universe are different things. Because the booking curve covers only properties that list 30% or more of their total rooms on OTAs, it comprises 87 properties / 7,110 rooms in Aomori, 183 / 10,215 in Iwate and 108 / 4,899 in Akita — roughly half to 60% of the total stock. Games delegations and officials are assigned through the lodging allocation center, and most of those rooms are consumed outside OTA allotments, so a 95% sell-through of OTA inventory does not necessarily mean entire properties are full, and conversely some properties with rooms left on OTAs are filled by allocation. The figures in this article should be read strictly as an interim picture of inventory sold on OTAs. How the official guidelines set rate standards and assignment procedures for lodging allocation is laid out from the original text in Aomori 2026 Sports Games Lodging: ¥18,000 Cap vs ¥5,900 Break-Even.

Rooms Left on Session Weekdays — Around 2,000 Combined Remain in Iwate and Akita

What matters in practice for operators is how many rooms remain in neighboring prefectures on session weekdays. Lining up the latest observations for Tuesday, October 13 to Friday, October 16 and Monday, October 19 to Tuesday, October 20, Aomori has 244–844 rooms left, falling below 400 except on Monday the 19th and the closing ceremony on the 20th. By contrast, Iwate has 1,269–2,173 and Akita 598–1,028, so the two prefectures together still hold about 2,000–3,200 rooms on session weekdays. Given that the observed LT is 4 to 11 days, these rooms will shrink further with last-minute bookings, but as a buffer for the last-minute demand that arises after Aomori is nearly full, weekday inventory in Iwate and Akita has ample depth.

The Disability Games Second Wave — Contained in Aomori, No Visible Spillover to Neighbors

Viewing the days around the Disability Games (Oct 23–26) at the same LT22, Aomori was at 97.4% on Oct 22 (Thu), 98.6% on Oct 23 (Fri) and 99.5% on Oct 24 (Sat), climbing back into the 99% range in the same shape as the start of the main session. Oct 25 (Sun) was at 93.1% and Oct 26 (Mon) at 91.0%; here too the exit eases, as on the last day of the long weekend. By contrast, Iwate was at 74.8%, 79.8% and 87.3% for Oct 22–24 and Akita at 82.3%, 79.6% and 84.1%, which cannot be said to exceed Miyagi’s 82.5%, 82.0% and 90.3%. Lodging demand for the Disability Games is smaller than for the main session and appears to be contained within what Aomori Prefecture can absorb. Akita’s somewhat high 87.0%, 89.9% and 83.6% for Oct 21–23 are values at the latest observation (LT12–14); aligned at LT22 they return to the same level as Miyagi, so it is more natural to read them as weekday demand in the autumn foliage season than as an Akita-specific factor.

Monthly ADR Outlook — October Running Well Above the Same Month Last Year in All Three Prefectures

Finally, for investors, the monthly estimated transacted ADR. October 2026, an estimate based on listed levels at the time of the survey, comes to ¥15,500 in Aomori Prefecture (N=177 properties), ¥10,500 in Iwate Prefecture (N=243 properties) and ¥13,300 in Akita Prefecture (N=168 properties), all substantially higher year on year than the finalized October 2025 figures of ¥8,300 in Aomori (N=182), ¥7,100 in Iwate (N=252) and ¥8,200 in Akita (N=171). However, estimates for future months are based on the listed prices remaining at present and reflect the level after cheaper rooms have sold first, so they tend to skew upward. The fact that high session-period rates show up not only in Aomori’s but also in Iwate’s and Akita’s October estimates needs to be interpreted together with the overlap of the foliage season and the three-day weekend, and the finalized figures await reconciliation from November onward.

Implications for Operators — Where to Pursue Cross-Border Demand and How to Design Pricing

To sum up, three implications can be drawn from the interim picture as of October 10. First, Aomori’s demand peaks stand at the start of the session (Oct 10–11) and the Disability Games Saturday (Oct 24), with relative slack on session weekdays and the day of the closing ceremony. For properties in Aomori Prefecture, rather than chasing rate on remaining weekday rooms, a rational design is to maintain sell-through at the same level as pre-session Phase II weekdays (92–97%) while reflecting the scarcity of Saturdays in price. Second, spillover to neighboring prefectures is modest — 3–4 points at the same stage and 3–9 points relative to the control prefectures — so the grounds for properties in Iwate and Akita to raise weekday rates sharply on the premise of Games demand remain thin. That said, because the average listed price of remaining rooms sits more than ¥10,000 below Aomori, properties in secondary-transport catchments — Morioka and Ninohe, which reach Hachinohe and Shin-Aomori in around an hour by Shinkansen, and nearby Hachimantai, as well as Odate and Kazuno, which reach Hirosaki on the Ou Main Line — have room to capture last-minute demand after Aomori’s remaining rooms run out with a “cheaper than Aomori, and within reach of the venues” pitch. Third, for sales managers at chains holding inventory across the wider region, since Aomori Saturdays fill from 45 days out while Iwate and Akita stay open until the last minute, an operation on prefecture-specific timelines should be effective: close Aomori allotments early to protect rate, and raise prices in neighboring prefectures in stages while watching movement just before the session.

The figures in this article are an interim picture as of the start of the session and will move daily with last-minute bookings and returned cancellations during the Games. After the closing ceremony we intend to look back using final observations and re-examine how far spillover to neighboring prefectures ultimately extended.

Frequently Asked Questions

Q. When is the main session of the Aomori 2026 National Sports Games?
The general opening ceremony is on Saturday, October 10, 2026 and the general closing ceremony on Tuesday, October 20, both at the New Aomori Prefecture General Sports Park in Aomori City.
