Chiba Port Arena

The Chiba Port Arena sits at the edge of the port district. Inside, the floor is wood, polished for the various games that pass through. The space is built for versatility rather than one specific pursuit. For the Altiri Chiba basketball team, the current setup is functional. The renovation completed in 2026 tightened the seating and added a handful of VIP boxes, creating a slightly more intimate feel than the original capacity of 7,512 allowed for. The change was made to meet the standards for the B.LEAGUE PREMIER division.

The building has not changed its name over the decades, though a sponsorship deal with Chiba Bank has added a new designation to the exterior signage. It is a practical venue that has hosted everything from the Asian Men's Volleyball Championship to wrestling events in its sub-arena. It does not have a history of name changes to sort through, which keeps the focus on the work happening on the court rather than the past.
