Our name and logo


mamoru means "to protect."


Our name comes from the Japanese word mamoru which means "to protect." We want to enable more consumers and businesses around the world to take action to protect our planet.





Our logo represents an appreciation of all natural things.

Our logo is an interpretation of a Japanese torii (gate) found at Japanese shrines. It is inspired by the belief that all natural things are sacred and have a kami (spirit). The logo represents an appreciation of all natural things and is a reminder for us to protect the natural world.
