The first live concert of MECHATU-A, the eight-member NIJISANJI unit made up of the groups Oriens and Dytica, took place on October 10, 2026.

Who is MECHATU-A
MECHATU-A is a collaboration unit of eight male NIJISANJI Livers drawn from two debut groups. Oriens debuted in March 2023 and consists of Saeki Itetsu (佐伯イッテツ), Akagi Wen (赤城ウェン), Usami Rito (宇佐美リト) and Hibachi Mana (緋八マナ). Dytica debuted in April 2023 and consists of Hoshirube Sho (星導ショウ), Murakumo Kagetsu (叢雲カゲツ), Koyanagi Rou (小柳ロウ) and Inami Rai (伊波ライ). The unit is described in Japanese media as active since 2025: a hero-themed MECHATU-A show was reported at Nijifes 2025, and its first mini album, On-Deck!, was released on July 22, 2026. The Animate store chain ran an event for the album, and Dytica held a talk event around the release.
This is also the first time the unit has been announced as a live concert in a real venue. A sponsor press release for the same date calls it the first “real-venue live” of the unit.
Ticket options and prices
The official announcement lists several ways to watch. All prices include tax, and a separate service fee is charged for each ticket.
- Main stream with goods: 10,500 yen (6,500 yen for viewing plus 4,000 yen for goods, shipping and handling), plus a 462-yen fee. Some tickets also come with an acrylic diorama bonus, though the announcement does not say which.
- Main stream only: 6,500 yen plus a 286-yen fee.
- Individual Liver Camera: 2,500 yen for each of eight cameras, plus a 110-yen fee each.
- Liver Camera set: 8,800 yen for either the Oriens set or the Dytica set, plus a 387-yen fee.
- Fixed venue camera: 2,000 yen for a full-stage view, plus an 88-yen fee.
The announcement says timeshift viewing is unlimited during the sales period, which means buying a ticket now gives access to the archive until it closes on October 28.
Time conversion for overseas viewers
- Ticket sales close: October 27, 23:59 JST = October 27, 14:59 UTC = 10:59 a.m. October 27 in New York (EDT) = 07:59 a.m. in Los Angeles (PDT) = 14:59 in London (GMT).
- Archive closes: October 28, 23:59 JST = October 28, 14:59 UTC = 10:59 a.m. in New York (EDT) = 07:59 a.m. in Los Angeles (PDT) = 14:59 in London (GMT).
European daylight saving time ends on October 25, 2026, so London is on GMT by the deadline, while the United States stays on daylight time until November 1.
Promotion around the concert
From October 4 to October 10, 2026, NIJISANJI ran street-vision advertising for the live: an Oriens video at Shibuhachi Hit Vision in Shibuya, Tokyo from 07:00 to 24:00, and a Dytica video at Tsutaya Ebisubashi Hit Vision in Dotonbori, Osaka from 08:00 to 24:00. The official notice asked passers-by not to block foot traffic or photograph in ways that obstruct others.
A sponsor, the inner-care brand ELLISS, gave every attendee one packet of a vitamin C shot product on the day and ran a coupon campaign that was valid until October 31. We mention it only because it appears in the official sponsor release.
The video above is the debut stream of Koyanagi Rou, one of the four members of Dytica, as listed in NIJISANJI’s April 2023 debut announcement.
