A sealed Japanese booster box contains 30 packs.

What is Storm Emeralda?

Storm Emeralda is a Japanese-language Pokémon TCG booster set in the current MEGA Evolution era, scheduled for release on July 31, 2026. Like other Japanese main-series sets, it leads with strong chase cards, refined artwork, and the print and foil quality Japanese editions are known for.

The set is tied to the wider Mega Rayquaza campaign running across the MEGA Evolution releases, which has put extra attention on this expansion in particular.

The headline: Mega Rayquaza ex

The card driving most of the conversation is Mega Rayquaza ex. Rayquaza has one of the most devoted followings in the franchise, and its past special-art and special-rare cards have a strong track record on the secondary market — several earlier Rayquaza cards have sold for over ¥100,000.

That history is exactly why collectors are watching Storm Emeralda closely. The open question for the community isn't whether the set is popular — it's whether this expansion's Mega Rayquaza ex chase card earns a place alongside those earlier cards.

What's in a sealed box

A sealed Japanese booster box of Storm Emeralda contains 30 packs. For collectors, a sealed box is the cleanest way to hold the set in its best condition and to chase the top cards directly, rather than buying singles after release at post-hype prices.

Why collectors are paying attention

  • A proven chase line. Rayquaza cards have a long history of strong collector demand.

  • Japanese-edition quality. Japanese print, foil, and packaging are prized by collectors worldwide.

  • Limited early supply. High-demand Japanese sets often sell through their first allocations quickly, and resellers add markups soon after.

Note: nothing here is a prediction of future value. Cards and sealed product can go up or down. Collect what you love, and buy from a source you trust.
