Japan has always had different holo patterns, ever since base set.
They look INSANE in person. The radiant charizard has like a pixelated holo pattern a long with the hearts.
But different images. Just checked some of my old scans, which don’t show the effects as well as your image. The Charizard has snowflakes. Many cards have hearts though. I see keys and whirlpools/rippling water etc. Seems like every card is unique. It’s the cute collection for a reason 
Really nice cards, think a really under rated set.
