Adhesive paper tape is known as "washi" tape outside of Japan, but "masking tape" when you're in Japan. There are zillions of designs available. We have just a few from the brands Sunny Sunday, for a vintage retro artisan vibe and a few quirky animal ones from Classiky. We'll be adding more to our range all the time.
For papercrafting, gift wrapping, journalling, card making and many many other uses washi tape is found in (almost) every home in Japan.
