Two nights under a half-open roof
Belluna Dome breaks the usual rules for a dome. The roof was built over an existing open-air ballpark, and the sides were left open between the stands and the canopy. Air moves through the building, and the temperature inside follows the evening outside.
That matters for an October weekend. NCT 127 play here on Saturday 24 and Sunday 25 October 2026. Late October evenings in western Saitama turn cool after dark, and fans who come in a single layer tend to regret it by the encore.
The venue is the home ground of the Saitama Seibu Lions baseball team. Older fans and maps still call it Seibu Dome or MetLife Dome. For a concert, the stage usually sits at one end of the field, with seats on the field floor and in the stands curving around it.
Getting to Seibu-Kyujo-mae
The station is the venue’s front door. Seibu-Kyujo-mae Station is the terminus of the Seibu Sayama Line and the small Seibu Yamaguchi Line, and the dome stands directly beside the platforms. You step off the train and the stadium is the first thing in front of you.
The usual route from central Tokyo:
- Take the Seibu Ikebukuro Line from Ikebukuro towards Tokorozawa.
- Change at Nishi-Tokorozawa for the Seibu Sayama Line, two stops to Seibu-Kyujo-mae.
- On big event days, Seibu often adds through trains and extra services on this line.
Allow about an hour from Ikebukuro. From Shinjuku, the Seibu Shinjuku Line reaches Tokorozawa, where you switch to the Ikebukuro Line for one stop to Nishi-Tokorozawa.
Tickets, fan club lotteries and names on seats
Japanese K-pop tickets work differently from most countries. Large dome dates in Japan are typically sold through lottery rounds: the official Japanese fan club first, then general lotteries on ticketing platforms. You apply, wait for the draw, and pay only if you win.
Tickets for these tours are commonly electronic, held in a ticketing app on a phone. Seat numbers often appear only shortly before the show. Many Japanese concerts also tie the ticket to the buyer’s name, and staff may compare it with photo ID at the gate.
Resale outside official channels is a real risk here. Japan’s ticket-scalping law covers named concert tickets bought for resale, and transferred tickets can be refused at entry.
Inside the dome: lightsticks, goods and etiquette
The Japanese crowd has its own codes. NCT fans carry the official NCT lightstick, and at many K-pop dome shows it connects to the central system so whole sections change colour together. Fans usually pair it with the app before the show, not inside the gates.
Merchandise booths outside the dome tend to open hours before the concert itself. Queues for goods are a ritual of their own, and popular items often sell out on day one of a two-night run.
During the show, the local norms are quiet but firm:
- Filming and photography are generally forbidden unless the artist announces otherwise.
- Fans stay within their own seat space and keep fan boards below head height.
- Chanting along to fanchants is expected; standing on seats is not.
Leaving without the crush
Getting out is slower than getting in. Tens of thousands of people head for one terminus station at once, so staff hold crowds outside and release them onto the platforms in waves. Waits of half an hour or more are normal after a full dome show.
Some fans linger at the goods area or walk the short path to the nearby Sayama Fudoson temple grounds while the first waves clear. Others leave during the final song, a choice that trades the encore for a seat on the train.
Fans travelling from Tokyo usually stay around Ikebukuro, where the Seibu line starts and hotel choice is wide. Tokorozawa city itself has a handful of business hotels near Tokorozawa Station.
Around the dome by daylight
The area around the dome is green and quiet. The stadium backs onto the Sayama Hills, and Lake Sayama and Lake Tama, two reservoirs serving Tokyo, are close by with walking paths along their banks.
Seibuen Yuenchi, a Showa-retro amusement park, is one station away on the Seibu Yamaguchi Line. For fans with a free afternoon before a weekend show, these places fill the hours better than a long wait at the gates.
Frequently asked questions
When and where is the NCT 127 Concert in Tokorozawa?
NCT 127 perform two shows at Belluna Dome in Tokorozawa, Saitama, on Saturday 24 and Sunday 25 October 2026.
What is the nearest station to Belluna Dome?
Seibu-Kyujo-mae Station, the terminus of the Seibu Sayama Line and Seibu Yamaguchi Line, sits right next to the dome. From Ikebukuro, take the Seibu Ikebukuro Line and change at Nishi-Tokorozawa; the trip takes about an hour.
How are tickets for Japanese NCT 127 dome shows usually sold?
Typically through lottery rounds, first via the official Japanese fan club and then via ticketing platforms. Tickets are commonly electronic, often name-linked, and photo ID may be checked at entry.
Is Belluna Dome warm inside in October?
Not reliably. The roof covers the stadium but the sides are open, so the inside follows outdoor temperatures, and late October evenings in Saitama get cool. Concertgoers usually bring an extra layer.
How long does it take to leave after the show?
Exits are staged, with crowds held outside Seibu-Kyujo-mae Station and released in waves, so waits of half an hour or more are common after a full dome concert.
