Ninja Spinner (M4) Booster Box (Japanese) | 30 Packs | Mega Greninja ex

Pokemon TCG Ninja Spinner (set code: M4) is a Japanese-language booster set released on March 13, 2026 as the fourth expansion in the MEGA Series, the era of the Pokemon TCG inspired by the Mega Evolution mechanic tied to the Pokemon Legends: Z-A video game. The main set contains 83 cards with 37 secret rares, for a total of 120 cards to collect. The English equivalent of this set is Chaos Rising, scheduled for release on May 22, 2026.

Ninja Spinner is themed around ninja-style Pokemon and fast, tactical Water-type and Dark-type gameplay, headlined by the debut of Mega Greninja ex — one of the most anticipated Mega Evolution cards in the history of the Pokemon TCG. Greninja consistently ranks among the most popular Pokemon worldwide, and this is its first-ever Mega Evolution card. The headline chase card is the Mega Greninja ex Mega Ultra Rare (MUR), the highest rarity in the MEGA Series. Other notable secret rares include Mega Greninja ex SAR, Cyclizar ex SAR, and Atticus SAR. Each box is expected to yield approximately 1 SAR, SR, or MUR, 3 Art Rares, and 4 Double Rares on average.

This set also carries collector significance as the final Japanese Pokemon TCG set released at the 180 yen per pack price point, before a price increase to 200 yen per pack takes effect from May 2026 onwards. Previous price increases in the Pokemon TCG have historically accelerated appreciation in pre-increase sealed products.

Box contents: 30 booster packs per box. 5 cards per pack. 150 total cards per box. Language: Japanese. All card text is in Japanese. Condition: Factory sealed.

Ideal for collectors chasing the Mega Greninja ex Mega Ultra Rare, competitive players building Mega Greninja ex decks, and sealed product investors looking to hold the final box at the pre-increase price point. Cards are randomised and specific pulls are not guaranteed. Recommended for ages 6 and up.
