Ninja Spinner release date and product details

Ninja Spinner releases in Japan on Friday 13 March 2026. If you are buying sealed Japanese product in the UK, the main thing you want to know is the box format: 30 booster packs per booster box, with 5 cards per pack. That gives you a nice, clean opening experience, and it is the standard style of Japanese mainline expansion.

If you want to secure a sealed box early, you can wishlist the product to be notified when its available: Pokémon TCG: Ninja Spinner Booster Box (JP).

“Ninja Spinner” all 83 main set cards revealed

The headline news is simple: all 83 main set cards have been revealed. The first secret rares have started appearing too, including Illustration Rares for Ampharos and Tauros, with more secret rares expected shortly.

If you like sets that feel coherent rather than random, Ninja Spinner has a clear identity. It continues the Mega Evolutions introduced in Pokémon Legends: Z-A, and it does not yet lean on the newer Mega Evolutions introduced later via the Mega Dimension DLC. Those newer Megas are expected to start appearing in the next Japanese set.

Mega Greninja ex in Ninja Spinner

Let’s be honest, Mega Greninja ex is doing a lot of the heavy lifting here, and for good reason. Greninja is already a fan favourite, and the Mega version is exactly the kind of card that makes people buy sealed product even if they swear they are not chasing this set.

On the gameplay side, Mega Greninja ex has an Ability that turns spare Water Energy into direct pressure, and its signature attack ties into the set name itself. The result is a card that feels like it can be both a collector chase and a real deck piece, depending on how the format develops.

If you pull it early, it is one of those “pause the opening for a second” hits. The only question after that is the classic one: are you sleeving it for play, or putting it straight into the binder and treating it like a trophy?

Key cards and themes to watch in Ninja Spinner

Ninja Spinner is not a one-card set. Mega Greninja ex is the headline, but there is plenty in the list that looks interesting for both collecting and play. Here are a few standouts that people are already talking about:

• Beedrill ex: A Beedrill-themed damage plan that scales with how many Beedrill you have in play.
• Mega Pyroar ex: Big firepower with a twist, plus the Mega Evolution prize rule makes every decision feel higher-stakes.
• Delphox line: Hand-filling support that can keep you moving when you would otherwise stall out.
• Crobat:  A “find what you need” style Ability that can smooth turns and set up plays faster.
• New Trainers and Special Energy: The sort of glue cards that end up mattering more than you expect once decks start refining.

If you are collecting Japanese sets for the art as much as the gameplay, keep an eye on the Illustration Rares as they finish revealing. Ninja Spinner already has that “binder-friendly” feel, where even non-Mega cards can look surprisingly premium.

How Ninja Spinner links to Chaos Rising in English

For UK collectors who mostly open English product, Ninja Spinner matters because it is widely reported to feed directly into Chaos Rising, the next English Mega Evolution-era set. That means Ninja Spinner is basically your early look at the cards and mechanics that are likely to shape the English release conversation.

If you are tracking the English side too, you can keep an eye on: Chaos Rising. (If product images or final details are not live yet, that is normal. English product pages often fill in closer to preorder windows.)

Important: until English product pages and official announcements are fully published, treat exact contents and product images as subject to change. The Japanese set is the solid reference point right now.
