The Alter Genesis booster box is the sealed product for SM12 “オルタージェネシス”, the final main expansion of the Sun & Moon era in Japan. Released September 6, 2019, it closed out the main expansion run with Arceus & Dialga & Palkia-GX at card 65.
This guide covers what is printed about a sealed Alter Genesis box, which GX cards lead the set, how the box is listed on our site, and how it relates to the Japanese-only spin-off pack that followed it a month later. We ship Japanese sealed product out of Tokyo; the listing prices below are the prices at the time of this update.
The SM12 and SM12A store prices and availability were checked on October 15, 2026. SNKRDUNK asking prices remain dated October 8, 2026.

Alter Genesis (SM12) has a main numbering run through 095, with secret-numbered cards above it, and is built around Arceus & Dialga & Palkia-GX at card 65 — its six numbered GX cards are all Double Rare.

The related Japanese-only spin-off, SM12A-Tag All-Stars, is currently listed at ¥188,423 (~$1,224) — a separate high-class pack, not a companion box for the same cards.

What’s in an Alter Genesis Booster Box
Alter Genesis was released in Japan on September 6, 2019 as the final main expansion of the Sun & Moon era. Its main numbering runs through 095; secret-numbered cards sit above it.
| Item | Value |
|---|---|
| Release date (JP) | September 6, 2019 |
| Main numbering | Through 095; secret-numbered cards sit above it |
| Pack count per box | 30, stated in the official SM12 launch feature |
| Cards per pack | 5, randomly inserted |
| Pack price (JP) | 150円 + tax |
The official product page gives 5 randomly inserted cards per pack at 150円 + tax. Its Alter Genesis SR launch feature also describes a 30-pack box containing an SR-or-higher card. That is a product-format statement from the original release; it gives no odds for a particular ADP print or other chase card.
