JP sets historically released 2–5 months ahead of EN; that gap has narrowed to ~5 weeks (OP-15, 2026) and is billed as ~1 week (OP-17, Aug 2026) — the first near-simultaneous worldwide release. Card pool and rarities match JP/EN; JP-exclusive God Packs and pack-size/price differences (12 cards/$4.99 EN vs 6 cards/¥220, rising to ¥240 from OP-17, JP) do not.
OP-01 "Romance Dawn": JP 2022-07-22 / EN 2022-12 (~4.5-month gap)
OP-05 "Awakening of the New Era": JP 2023-08-26 (1st-anniversary set)
