A free collection tracker for Japanese Pokémon and One Piece cards

Why Japanese prices?
Most collection apps show US prices, often converted from English cards. Japanese cards trade in Japan: we show what Japanese shops ask and what Japanese buyers paid, in yen. How we price
Which cards?
Japanese Pokémon (from the classic sets to MEGA) and Japanese One Piece (every booster, extra booster, premium booster, starter deck, promos, DON!! cards), plus sealed boxes and packs. English Pokémon cards are listed with an overseas reference price.
