Allocation The 2025–26 East Asia Super League featured twelve teams, up from ten in the previous season. Taiwan's (Chinese Taipei)
P. League+ (PLG), Japan's
B.League and South Korea's
Korean Basketball League (KBL) each have two slots allocated for the finalists of their respective leagues. On 13 May 2025, a third slot was given to the B.League, allocated for the champion of the Emperor's Cup. On 24 July, the league also gave Chinese Taipei a third slot, which was given to the
New Taipei Kings, champions of the
Taiwan Professional Basketball League (TPBL). The Philippines'
Philippine Basketball Association (PBA) was allocated one slot, down from two in previous seasons. This is due to the PBA assessment that sending two teams would be difficult considering its busy schedule for the
2025–26 season. The allocation process for the lone Philippine representative was to be confirmed since the PBA has multiple conferences or tournaments for its
2024–25 season. Champions
TNT Tropang Giga and
San Miguel Beermen opted out from participating. On 30 July, the PBA announced that the
Meralco Bolts would be the representative for the Philippines, a decision determined through a vote. On 24 January 2025, the EASL announced that Mongolia's
The League would be represented in the league for the first time. The League is given one slot for the league champions. Continuing from the previous season, Macau and Hong Kong would each have one team joining the EASL.
Hong Kong Eastern in particular are contracted to participate regardless of placing in the domestic league. The
Macau Black Bears would also return.
