-In Japan, Marimo Moss Ball are a token of everlasting love.

-The legend tells Minabe and Senato were lovers. Their only desire was to be together forever. But their love was forbidden and they run away. Sadly, they fell into the water of the Lake Akan , and their hearts became Marimo balls. 

-They live 100+ years. The endurance of the moss balls has become a poetic representation of the love that can endure the weathers of time and tribulations.

-They are not moss. They are a rare growth form of spherical alga (Aegagropila Linnaei).

-This alga is solid with no central stone or kernel inside. Its radius from the centre, growing radially outward very very slowly, 5mm per year.

-They get “pregnant”. For reproducing, Marimo Ball starts developing a “belly” that when enough big, it will live by itself, separated from the "mother".

-Natural from the very cold Lakes of Japan, Estonia, Iceland, Scotland and Australia.They have also been found in oceans. 

-They are disappearing from the Lakes.  An excess of nutrients (due to agriculture and fish farming) and mud deposition from human activity are thought to be the main causes for its disappearance from many lakes.

-Protected in Japan since the 20s and in Iceland since 2006.

-In Japan, the Ainu people hold a three-day Marimo Festival every October at Lake Akan.

-They naturally absorb toxic nitrates in water and act like miniature filters, cleaning the water.

    -You can use tap water. Try to let it sit out for a day for better results.

    -Change the water and clean the container every two to three weeks (ideally, you can take longer). It will depend on the size of the container, the amount of warmth and the light it gets.

    -In summer, do it more often, as it will heat and evaporate more quickly. 

    -Clean your Marimo enclosure with a brush if algae begin to grow on the tank surface.


    -Marimo’s grow on the bottom of the cold lakes. They don’t like direct sunlight or warm temperatures. 

    -Keep your Marimo balls away from sunny, exposed windows.  They will live much longer and be much healthier.

    -They adapt, grow and can photosynthesize just fine with your household lights or low light from non-direct sources of sunlight.
