Pokemon Storm Emeralda (M6) Booster Box - Japanese

Storm Emeralda Japanese Booster Box

Storm Emeralda is one of the major Japanese Pokémon TCG releases of the MEGA era and puts Mega Rayquaza ex at the centre of the set.

Officially released in Japan on July 31, 2026, Storm Emeralda carries the Japanese set code M6. Each booster box contains 30 packs, with 5 randomly inserted cards inside each pack. That means one full box contains 150 Pokémon cards before accounting for duplicate cards.

The main numbered set contains 76 cards, followed by additional Art Rare, Super Rare, Special Art Rare and top-rarity cards extending the numbered checklist through #113.

For collectors, Storm Emeralda is particularly notable for bringing Mega Rayquaza back into the spotlight.

Why Collect Pokemon Storm Emeralda?

Mega Rayquaza ex is the defining Pokémon of Storm Emeralda and appears in several versions throughout the set.

Among the higher-rarity cards are Mega Rayquaza ex #110 and Mega Rayquaza ex #113, alongside Special Art Rare cards featuring Raikou ex, Mega Golurk ex, Mega Golisopod ex, Zinnia's Trust and Aarune.

Collectors can also find Art Rare versions of Pokémon including Groudon, Kecleon, Altaria, Growlithe and others.

The result is a set with appeal across several types of Pokémon collectors. Rayquaza collectors have major chase cards to pursue. Hoenn fans get familiar Pokémon and characters. Mega Evolution collectors get another key M-series release. Japanese-card collectors get the original version of cards that are scheduled to appear in the English Delta Reign expansion.
