What this is
How many Pokémon card products came out in Japan each year: about 6 a year from 2010 to 2015, then about 11 a year from 2017 to 2025.
How it’s built
- Count products in the official Japanese product list by The Pokémon Company's financial year (March to February).
- Average 5.67 a year for the six years to February 2016; 10.67 for the nine years to February 2026, 1.88 times higher.
What we assumed
- Every listed product counts as one, including two deluxe re-packs in the latest year.That is how the official list shows them; on distinct sets the later average would be a little lower.
- Products were sorted into main and special packs by their titles.A simple rule applied once; it has not been checked a second time.
Sanity check
The step up happened around 2017–2018, four years before card printing jumped in 2021–22. So more products do not explain the print surge.
Where it comes from
Our calculation from other figures in the trainer’s notes.
Show the working
- Year to February 2011-year to February 2016 products per year: 4, 5, 8, 4, 6, 7
- Mean pre: 5.67
- Mean post: 10.7
- Ratio: 1.88
- (transition), year to February 2017: 9
- mean([4, 5, 8, 4, 6, 7])=5.67
- mean([13, 12, 12, 8, 11, 10, 11, 8, 11])=10.67
- ratio 1.88
