MONSTA X’s Chiba concerts have put the Japan leg of 2026 MONSTA X WORLD TOUR [THE X : NEXUS] firmly in motion. The group opened the Japan dates at LaLa Arena TOKYO-BAY in Chiba on April 28, 2026, with a second Chiba performance set for April 29 before the tour continues to Osaka in early May.1
For fans following the MONSTA X Japan Tour, the Chiba stop matters because it is the first Japan stage of the wider THE X : NEXUS world tour. The Japan run follows earlier tour movement through Seoul, Bangkok, Kuala Lumpur, Taipei, and Jakarta, placing Chiba in a key mid-tour position rather than treating it as a standalone event.1
MONSTA X Chiba Concerts Open the Japan Run

The Chiba schedule is simple but important: MONSTA X performs at LaLa Arena TOKYO-BAY on April 28 and April 29, 2026. The official Japan ticket notice listed these two Chiba dates alongside two Osaka dates, confirming a four-show Japan schedule for 2026 MONSTA X WORLD TOUR [THE X : NEXUS] IN JAPAN.2
The first Chiba performance on April 28 was also listed by PODA as a concert and live event, with doors at 17:30 and the show beginning at 18:30. The same listing named MONSTA X as the performer and advised readers to check the official site because schedule details can change.3
What makes this opening especially appealing for fans is the structure reported for the tour. The Japan leg includes a mix of hit-song medleys and individual stages, which gives the concerts both a group-focused scale and room for each member’s own color.4 That kind of format fits a tour designed to look back across MONSTA X’s career while still presenting where the group is now.
The lineup context also adds weight to the stage. Earlier coverage of the Seoul concerts described THE X : NEXUS as a full-group performance involving Shownu, Minhyuk, Kihyun, Hyungwon, Joohoney, and I.M.5 For longtime listeners, that detail is central because the Japan opening is not only another arena stop; it is part of a world tour framed around MONSTA X’s complete group presence.

The table shows why the Chiba stop is the natural focus. It is the start of the Japan arena sequence, but it also sits inside a clearly defined four-performance run. After the two Chiba shows, MONSTA X heads to Osaka for concerts on May 3 and May 4 at Ookini Arena Maishima.4

The same notice listed reserved seats at 15,400 yen including tax, giving fans one of the clearest official reference points for the Japan shows.2
How Chiba Fits Into THE X : NEXUS
The Chiba concerts are not the beginning of the entire tour. MONSTA X started THE X : NEXUS with three Seoul concerts at KSPO DOME from January 30 to February 1, 2026.5 That earlier Seoul run established the tour before its later movement into international cities and the Japan arena dates.
Live Nation also described the broader tour as covering songs from MONSTA X’s 11-year career along with material connected to the group’s third English-language studio album, Unfold, released on April 3, 2026.6 That helps explain why the Japan performances are drawing attention beyond the usual schedule news: the concerts sit at the intersection of anniversary-era reflection, current releases, and global touring momentum.
The Japan opening also comes before the announced North American dates, which begin October 3, 2026, in Fairfax and continue through October 24 in Seattle.6 In that sense, Chiba is part of a longer 2026 tour arc that stretches well beyond Asia.
