Three men in their 20's and 70's were reportedly arrested on suspicion of trespassing after allegedly entering Tokyo Dome during Arashi's final concert on May 31.

According to reports, one man in his 70's allegedly posed as a staff member by wearing a helmet to gain access to the venue. He reportedly told investigators that he intended to sell photos taken at the concert.

The two younger men are suspected of using staff IDs obtained while previously working part-time for an event company, with one also allegedly using a forged ID card to enter the venue.

Because the concert was limited to fan club members and utilized facial recognition technology, the incident has sparked concern and criticism online over how the suspects were able to bypass security measures.

Fans on social media questioned the venue's security system, with some expressing disbelief that methods resembling those seen in dramas or anime were allegedly used in a real-life incident.

Arashi held the final performance of their farewell tour, 'ARASHI LIVE TOUR 2026: We are ARASHI,' at Tokyo Dome on May 31, officially concluding the group's activities after more than 26 years together.
