While I agree with this in spirit, technically isekai means another world, and the world that Ash was sent to was our world in the past.
So, if we're looking at isekai in spirit. I think Futurama would be included as a good example. Oh, Final Fantasy X too. Although gray area.
More counterpoints: Superman, Super Mario Bros, Dragonball, Lilo and Stitch, The Amazing Digital Circus, Spirited Away, Back to the Future, Homestuck, Hercules, Undertale, The Matrix, Fern Gully, Harry Potter, Genshin Impact
My favourite Isekai is the story of Jesus Christ, who came from Heaven to "another world" called Earth

I don't remember the Necronomicon from history class ;-)
Thank Ash for that 🙏
