How it’s built
- Read in the price-revision notice on the official Japanese Pokémon card site, announced 30 January 2026.
What we assumed
Nothing. The figure is used as published.
Sanity check
The rise is about 11%, and the notice says products released before May keep their old price; Japanese press reported the same figures.
The values
- Old ¥ incl tax: 180
- New ¥ incl tax: 200
- Applies to: new products released from May 2026
- Reason: 原材料費の高騰
