The Pokemon Company has confirmed that prices for pokemon tcg products in Japan will go up starting with the Scarlet and Violet era. This is to cover rising manufacturing and distribution costs although we don’t know if this means more and better holo card ratios in boosters for example as a specific reason for the price increases in booster packs. Prices for tcg products from the Sword and Shield era won’t change.

The chart below showcases updated prices on average. More and more people outside of Japan are into buying and collecting original Japanese pokemon tcg products so these changes should be taken into consideration. Price increases have already taken effect in Europe and North America so perhaps this only Japan catching up.
