What is Ninja Spinner?
Ninja Spinner is a Japanese Pokémon TCG MEGA expansion pack (set code M4) that spotlights Greninja’s ninja identity — with Mega Greninja ex positioned as the headliner. Officially, it’s part of Japan’s MEGA expansion line-up, with packs sold in the Japanese market and later absorbed into international English releases. For collectors in the UK, the appeal is simple: Japanese print quality, earlier access to new cards, and that “first wave” buzz around chase hits.
Release Date & Details
The Japanese Pokémon Ninja Spinner release date is 13th March 2026, confirmed on the official Pokémon Card Game product page. Each booster pack has 5 cards and a Japanese MSRP of 180 yen per pack. (Official Pokémon Card Game: Ninja Spinner (M4))
On the UK retail side, Pixel Hub lists the Ninja Spinner booster box as a pre-order item with a stated dispatch timing of 17 March once stock lands in the UK. (Pixel Hub product page)
Key Cards & Rarities
The obvious headline is Mega Greninja ex Ninja Spinner — the card most collectors will be chasing first. The official set page highlights Mega Greninja ex and showcases key supporting cards like Big Catch Net (大漁ネット) and Bubble Water Energy (バブル水エネルギー), pointing to a Water-leaning, tempo-friendly theme. (Official set page)
Set coverage from established TCG news sources also reports the main set size as 83 cards (plus secret rares), which is a helpful benchmark when you’re tracking card lists and planning what you want to master set. (PokéBeach report)
Collector tip: If you’re buying for the chase, keep an eye on the official card list page (linked from the product page) as it fills out — it’s the quickest way to confirm which trainer cards, evolutions and special illustrations are actually in the set. (Official card list hub)
Pack Contents & Pull Rates
Here’s what we can say with confidence (and what we can’t):
- Confirmed: 5 cards per pack, MSRP 180 yen per pack, release date 13 March 2026. (Official source)
- Typical (but not officially published as “pull rates”): Japanese booster boxes are usually consistent enough to be “fun to open”, but exact hit distributions vary by product line and are not guaranteed box-to-box.
Because The Pokémon Company doesn’t publish official “pull rate” tables for sets like this, treat any fixed numbers you see online as community averages, not guarantees. The practical way to approach Ninja Spinner is to decide what you’re collecting: sealed box investing, opening for hits, or building singles.
Opening strategy (UK collector friendly):
- Chasing Mega Greninja ex? Buy sealed, open early, and trade duplicates fast while demand is hot.
- Building a binder set? Open 1 box for the experience, then fill gaps with singles.
- Long-term hold? Keep at least one box sealed and store it cool, dry, and upright.
UK Availability & Price
Japanese sets can be tricky in the UK because demand spikes around release week and stock is often limited. If you’re aiming to open on (or close to) launch, the safest play is a UK-dispatched pre-order with a trusted retailer.
At the time of writing, Pixel Hub lists the Ninja Spinner booster box (M4) at £99.99 and notes UK shipping and collector-focused packing. (Pixel Hub listing)
