We are so happy that you found us. Thank you very much!

My name is Hiroki Matsuuchi. Marimo (actually my wife's nickname) and I are the two people who run the Marimo Marshmallow Store with the occasional help of our three year old son and infant daughter.

Our journey started with a video on YouTube about five years ago. We started with a couple of items being packed and shipped from our apartment's kitchen table and created the Marimo Marshmallow Store from the ground up.

This is not the end of this glorious story, in fact it's just the beginning! Thank you for being part of it :)

Please, feel free to contact us at any time.
