The Grand Sumo May Tournament will be held at Ryogoku Kokugikan from Sunday, May 10 to Sunday, May 24, 2026 — a 15-day run. Unlike one-off mega-events such as concerts or fireworks festivals, a grand sumo tournament (honbasho) is a rare event where every single day of the 15-day period is a demand day. This article aggregates daily OTA published price data from 35 hotels within walking distance (1.5 km radius) of Ryogoku Kokugikan and quantitatively analyzes the tournament’s impact on accommodation demand, ADR, and sellout rates in the Ryogoku area — benchmarked against the same period last year and non-tournament periods. The conclusion: while demand is indeed elevated year-over-year, ADR response remains limited, and particularly on Sundays, significant revenue opportunities remain untapped.

The Unique Nature of a 15-Day Consecutive Sumo Tournament

Of the six annual grand sumo tournaments, three are held in Tokyo: January (Hatsu Basho), May (Natsu Basho), and September (Aki Basho). The remaining three take place in Osaka (March), Nagoya (July), and Fukuoka (November). This means Ryogoku Kokugikan hosts three tournaments per year — 45 tournament days total — making it an extremely important demand driver for accommodation in the Ryogoku area.

The May Tournament opens on Sunday, May 10, 2026, with the middle day (nakabi) on Sunday, May 17, and the final day (senshuraku) on Sunday, May 24, creating three Sunday peaks across the 15 consecutive days. This “15-day consecutive” characteristic differs fundamentally from the demand pattern of typical one-off events like a single concert, fireworks show, or sporting match. Each day brings new spectators to Ryogoku who settle into their box seats in the morning and stay until the final bouts conclude in the evening — a pattern that repeats for 15 days, generating accommodation demand not as “peak-day concentration” but as “sustained elevation across the entire period.”

In recent years, the surge of international spectators has been widely reported. According to Japan Today (2025), all six 2024 honbasho tournaments achieved 90 consecutive days of sellouts — a first in 30 years. The Japan Sumo Association also recorded its highest-ever revenue in 2024 and will hold its first overseas exhibition in London in 30 years in October 2025. Sumo has transformed into a major draw for inbound tourism. Matador Network (2026) reported that “2026’s most surprising travel trend is sumo wrestling,” reinforcing that the May Tournament is no longer merely a domestic event for the Ryogoku area but one that increasingly attracts international travel demand.

Daily ADR Trends for Hotels Near Ryogoku Kokugikan (May 2026)

Let us examine the actual accommodation price data. For the 22 properties within a 1.5 km radius of Ryogoku Kokugikan, we compiled daily ADR and sellout rates from May 1 to May 31, 2026. The key question: how do the 15 tournament days (May 10–24) differ from the regular weeks before and after?

Three structural patterns emerge from the chart. First, the May 3 (Sunday) peak of ¥30,200 reflects Golden Week’s final weekend — a holiday-driven spike unrelated to the sumo tournament (for a detailed analysis of city-level ADR trends during GW, see our GW 2026: 6-City Hotel Price YoY Analysis). Second, weekday ADR (Tuesday–Thursday) during the tournament period (May 10–24) ranges from ¥22,800 to ¥25,900, roughly 15–24% higher than the same weekdays post-tournament (¥19,800–¥20,900). Third, and most notably, ADR on the three tournament Sundays (May 10, 17, 24) at ¥18,000–¥19,900 is barely different from regular Sundays after the tournament (June 7 and 14 at ¥17,200–¥17,500). Demand is clearly elevated, but pricing has not adequately responded.

During vs. After Tournament: The Two Faces of Day-of-Week ADR and Sellout Rates

To more clearly demonstrate the presence of demand, we averaged ADR and sellout rates by day of the week for the tournament period (May 10–24) versus the post-tournament period (May 25–June 14).

During the tournament, weekday ADR (Tuesday through Friday) is ¥3,000–¥5,000 higher than the same weekdays post-tournament, with sellout rates also 8–10 points higher. This is clear evidence that sumo spectator demand is layering on top of regular business travel demand. For baseline context on weekday business demand across major cities, see our Tokyo, Nagoya, Osaka & Fukuoka Weekday ADR Deep Dive. Meanwhile, Sunday ADR during the tournament (¥19,100) is actually lower than post-tournament (¥20,000). However, the sellout rate tells a different story: 27.2% during the tournament versus 18.4% after — a 9-point gap. In other words, Sunday demand is rising but prices are not responding, representing a significant untapped revenue opportunity.

The table reveals that weekdays show uplift in both pricing and sellout rates, while Sundays see only sellout rates leading the way. Since spectators attend daily bouts, the accommodation pattern tends toward Sunday night stay with Monday departure (to catch Sunday’s matches) rather than Saturday night stay with Sunday departure, concentrating demand on Sunday nights.

Year-over-Year Comparison (May 2025): Qualitative Shifts in Demand

Another critical perspective is the comparison with last year’s May Tournament (May 11–25, 2025, with nearly identical scheduling). ADR and sellout rates were measured for the same 22 properties.

The most striking change is the sharp rise in sellout rates. During last year’s tournament, the three Sundays (May 11, 18, 25) showed 0.0% sellout — meaning all OTA plans were still accepting reservations at the time of survey. In contrast, the 2026 average across the three Sundays is 27.2%. This indicates dramatically stronger demand compared to the prior year, consistent with the Japan Sumo Association’s reports of “90 consecutive sellout days in 2024” and “record-high revenue in 2024.”

ADR levels themselves are largely flat to slightly lower year-over-year: Ryogoku View Hotel dropped from ¥25,800 to ¥23,300 (YoY -10%), Dai-ichi Hotel Ryogoku (第一ホテル両国) from ¥20,200 to ¥18,700 (YoY -7%), while Henn na Hotel Tokyo Asakusabashi (変なホテル東京 浅草橋) and Pearl Hotel Ryogoku (パールホテル両国) maintained prior-year levels. The picture is clear: demand is surging while prices remain essentially unchanged — indicating that significant revenue opportunities are being left on the table across the entire Ryogoku area.

Hotel-Level Sellout Rates: Dai-ichi Hotel Ryogoku at 40–58% Occupancy

Examining individual hotel performance reveals even starker demand concentration. Dai-ichi Hotel Ryogoku (第一ホテル両国), the largest city hotel within walking distance of Ryogoku Kokugikan (334 rooms), recorded daily sellout rates of 40–58% during the tournament — far exceeding the area average of 27%.

Dai-ichi Hotel Ryogoku’s sellout rates on the three key Sundays were consistently high: 54.1% on opening day (May 10), 57.7% on the middle day (May 17), and 55.7% on the final day (May 24). Meanwhile, ADR remained within a narrow range of ¥18,000–¥19,200. Given the hotel’s prime location (2-minute walk from Ryogoku Station, 3 minutes from Kokugikan) and scale (334 rooms), its strong ability to capture demand is well proven. Combining this with step-up pricing — for example, raising rates by 5% when 25% of Sunday inventory is sold and another 5% at 50% sold — could meaningfully increase the average transaction price.

The Inbound Sumo Spectator Boom and Ryogoku’s Position

Tickets for the May 2026 Tournament are being sold through multiple travel agencies (KNT, Yomiuri Travel, Tabiccus, VIP Tour, etc.), and the Japan Sumo Association’s official fan club pre-sale lottery consistently sees high application ratios. Pia (Ticket Ozumo) sales data shows that box seats (masu-seki) and ringside seats (tamari-seki) routinely sell out early.

International visitor engagement is also growing. The Japan Sumo Association launched its English YouTube channel “Sumo Prime Time” in 2022, which had approximately 100,000 subscribers as of 2026. English-language travel media such as Magical Trip, Japan Wonder Travel, and Stripes Japan regularly feature Ryogoku Kokugikan spectating combined with “morning practice viewing tours” as standard content. Sumida City Tourism Association’s medium-term business strategy (2023–2025) also positions expanding foreign tourist accommodation and spending in the Ryogoku and Honjo areas as a priority initiative.

Given these structural changes, hotels in the Ryogoku area have already begun transitioning from the traditional image of “sumo spectating = domestic senior-focused traditional demand” to “diverse demand mixing domestic and international inbound visitors.” For background data on the tectonic shift where foreign guest ratios have settled above 50% across Tokyo, see our Japan Tourism Agency January 2026 Deep Dive: Tokyo’s Foreign Guest Ratio Surpasses 50%. Combined with the 15-day consecutive event characteristic, Ryogoku sees an extraordinarily dense layering of weekday business demand, weekend leisure demand, Golden Week holiday demand, and tournament spectator demand all overlapping.

Advice for Readers: Booking Timing and Looking Ahead

From a consumer perspective, booking accommodation in the Ryogoku area during the May Tournament reveals that tournament Sundays offer the best value. Compared to Saturday nights, Sunday rates are more than ¥10,000 cheaper, essentially matching post-tournament regular Sunday ADR levels — all while securing a location within walking distance of Kokugikan. Meanwhile, weekdays (Tuesday–Thursday) see higher prices due to competing business travel demand, making Sunday stays the rational choice for cost-conscious spectators.

From a hotel operator’s perspective, preparation for the next tournament immediately after the May Tournament is crucial. The next honbasho is the Nagoya Tournament from July 12–26, 2026 (the first held at IG Arena), followed by the September Aki Basho from September 13–27, 2026 (back at Ryogoku). Since the September Tournament is again at Ryogoku Kokugikan, operators have time to prepare multiple levers before then: early pricing adjustments aligned with weekday demand, step-up rate increases tied to Sunday sellout progression, and expanded inbound-focused rate plans. We recommend aggregating May Tournament daily sellout data by day of week and building a step-up pricing schedule starting three months ahead (June) for the September Tournament.

For readers planning sumo spectating trips to the Ryogoku area, we recommend booking accommodation early in conjunction with the January 2027 Tournament ticket release (typically late February). Data shows that Saturday nights (above ¥30,000) and weekdays (around ¥25,000) tend to see inventory thin out within days of ticket sales going live.

Summary

The Grand Sumo May Tournament 2026, running from May 10 to 24, is a rare event creating 15 consecutive “demand days.” Our daily analysis of OTA published price data from 22 hotels within walking distance of Ryogoku Kokugikan revealed three key findings:

Sumo is now transforming into a major draw for inbound tourism. For hotel operators in the Ryogoku area, the May Tournament is not merely a seasonal event but an ideal opportunity to visualize demand curves and refine pricing strategies ahead of the September Aki Basho. We hope the data in this article supports data-driven revenue management decision-making.
