Delta Reign Japanese Booster Box (Storm Emeralda)

Import allocation, capped and confirmed. This is the Japanese-language release of Delta Reign, known in Japan as Storm Emeralda (M6), the Mega Rayquaza ex expansion. Japanese sets print ahead of the English release and are prized by graders for sharper print quality.

Factory sealed, 5 cards per pack. Releases in Japan on July 31, 2026. Sourced through our official import allocation, capped at what we can actually confirm, we do not oversell.

Note: this is Japanese-language product. The English-language Delta Reign booster box (36 packs) releases separately on November 6, 2026.
