Naoya Inoue vs Junto Nakatani Set for May 2 Super Bantamweight Title Fight at Tokyo Dome
Japanese boxing has its biggest domestic showdown in decades locked in, as Naoya Inoue will defend his undisputed super bantamweight championship against Junto Nakatani on May 2, 2026, at the Tokyo Dome in Tokyo. The bout is scheduled for a Saturday night slot and will headline what is being billed as one of the most significant boxing cards ever staged in Japan.
Naoya Inoue vs Junto Nakatani Booked
Naoya Inoue enters the fight with a record of 32–0, 27 by knockout, and holds the Ring, IBF, WBA, WBC, and WBO titles at 122 pounds. He has been active through 2025, going 4–0 with wins over Kim Ye‑joon, Ramon Cardenas, former unified champion Murodjon Akhmadaliev, and the last‑result division top‑10 contender Alan Picasso by unanimous decision. Inoue currently sits around No. 2 on The Ring’s pound‑for‑pound list, giving the bout heavyweight significance despite the weight class.
Junto Nakatani arrives at 32–0, 24 knockouts, and made his 122‑pound debut in December 2025 on “The Ring V: Night of the Samurai” card, edging an unbeaten opponent, Sebastian Hernandez, by a controversial unanimous decision. Nakatani is a former three‑division world titleholder, having won titles at flyweight and junior bantamweight, then unified belts at bantamweight before moving up to super bantamweight. He is ranked No. 7 on The Ring’s pound‑for‑pound chart, and this fight represents a direct shot at becoming a four‑division champion and snapping Inoue’s reign.
Venue and historical context
The Tokyo Dome, a 65,000‑seat indoor baseball stadium in Bunkyo, Tokyo, has not hosted a major boxing event since 2003, making the May 2 date a rare return to the arena for a high‑profile fight. Inoue already has a notable history at the venue, having knocked out Luis Nery there in May 2024 in front of a near‑full crowd, which helped cement his status as Japan’s top draw. The scheduling of the May 2 date also had to work around the Dome’s existing calendar, with professional baseball and football events booked from May 3 onward, leaving the weekend preceding that block as the only viable slot.
Build‑up and promotional angle
The fight has been discussed publicly since Inoue and Nakatani appeared together at a 2024 Japanese Boxing Commission awards event, where Inoue called for a domestic showdown and Nakatani accepted the challenge on the spot. The pairing remained on parallel tracks for over a year, with fight‑weekend rumors swirling around May dates before promoters and networks aligned on the May 2 slot. WBC president Mauricio Sulaimán has backed the matchup, framing it as a historic all‑Japan collision that fits the Dome’s legacy, which includes Mike Tyson’s first career loss to James “Buster” Douglas in 1990.
Reports indicate that the Tokyo Dome card will likely feature multiple title bouts around the Inoue–Nakatani main event, targeting a full‑night stadium‑style show rather than a standalone 12‑round contest. Broadcasting will center on DAZN’s global platform, with The Ring’s Mike Coppinger and “Inside The Ring Show” providing behind‑the‑scenes coverage and analysis ahead of the fight. With both fighters unbeaten, both in the sport’s pound‑for‑pound top 10, and both carrying genuine knockout power, the matchup is expected to test the Tokyo Dome’s ticket‑sales capacity for a domestic boxing card.
