Pokémon

How many cards are in a Japanese booster pack, and how many packs come in a box?

Published · By the Cards from Japan editors

Summary

The official Japanese product pages for Pokémon, ONE PIECE and GUNDAM cards state the cards per pack and the price per pack, and those figures are in the tables below. The pages checked for recent sets do not state how many packs a booster box holds or what a box costs, and none publishes pull rates; each one says only that cards are packed at random. A few products promise one card of a given type in every pack, and those promises are the only rare-slot facts the publishers put in writing.

What the official pages do and don't tell you

Every product page checked here lists the release date, the contents of one pack and a manufacturer's suggested retail price per pack, including Japan's consumption tax. None of the pages for the sets in the tables gives a pack count for a box, a box price or an odds table. The line that does appear on all of them is ※カードはランダムに封入されています (cards are packed at random).

So a pack count you see on a shop listing, such as "30 packs" or "24 packs", comes from the shop or the distributor, not from these pages. For Pokémon, one official page did define a box as 30 packs in the terms of a purchase promotion; the booster box guide covers that case and the many products that carry "BOX" in their name without being boxes of packs. Pack, box, case and single explains the general terms.

Pokémon Card Game

Sets from M3 on are listed under their Japanese titles. Standard expansion packs went from ¥180 to ¥200 with M5 in May 2026 and stayed at 5 cards. High-class packs hold 10 cards at ¥550; the Terastal Festival ex guide looks at one in detail. Pack size and price across older Pokémon products shows the same spread going back further.

ONE PIECE Card Game

Prices are the manufacturer's suggested retail price per pack, tax included, from onepiece-cardgame.com. The pages give a card-type count with each pack, for example "全131種+4種" (131 card types plus 4).

SetCodeReleasedCards per packPrice per pack

Heroines Edition vol.2 (extra booster)EB-05Oct 31, 20266¥240
神の支配 (booster), upcomingOP-18Nov 21, 20266¥240

The price rose from ¥220 to ¥240 with OP-17 in August 2026. The ONE PIECE pages also list how many card types exist at each rarity. OP-17, for instance, has 45 commons, 30 uncommons, 26 rares, 10 super rares, 3 secret rares, 1 treasure rare, 6 leaders, 10 special cards and 4 DON!! cards. Those are counts of different cards in the set, not the chance of pulling one. Whether a box gets you the whole set is a separate question, answered in the guide to completing a One Piece set, and what is inside a One Piece box covers box-topper cards.

GUNDAM CARD GAME

Prices are per pack, tax included, from gundam-gcg.com.

SetCodeReleasedCards per packPrice per pack
Newtype RisingGD01Jul 26, 20256 + 1¥242

Freedom AscensionGD05Jul 25, 20266¥250
Stardust TrailsGD06Oct 31, 20266¥250

The earlier pages write the contents as "6枚+1枚" without saying what the extra card is; the GD05 and GD06 pages list 6 cards. GD07 is on the product list for January 30, 2027, with no price yet. The list of Gundam booster sets has the full run.

Guaranteed slots

No page checked here gives a 封入率 (insertion rate), but some state a per-pack guarantee:

Anything beyond that, such as "one SAR per box" or a rate for a secret rare, is not on these official pages. Numbers like that come from buyers' own counts, and what AR and SAR mean is the place to start before trusting one.
