Himematsutake
In 1975, a Japanese mycologist named Dr. Inosuke Iwade achieved the first reliable artificial cultivation of Agaricus blazei Murrill, the mushroom Japan calls Himematsutake — 'the princess matsutake'. Fifty years later, the Iwade Institute still cultivates the same strain (registered as ITO-S), in the same way. Yotsuba Japan's Himematsutake tablets deliver 737.5 mg per daily serving — paired with folate, which contributes to the normal function of the immune system.

FIFTY YEARS OF JAPANESE MYCOLOGY
In 1975, Dr. Inosuke Iwade achieved the first reliable artificial cultivation of Agaricus blazei Murrill — the mushroom Japan calls Himematsutake, "the princess matsutake." Fifty years later, the Iwade Institute of Mycological Research still cultivates the same registered strain, ITO-S, named after leading researcher Dr. Hitoshi Ito.
BOTH HALVES OF THE MUSHROOM
Each five-tablet daily serving delivers 737.5 mg of Himematsutake as a 50/50 blend of fruiting body and mycelium with its culture filtrate. Most Western mushroom supplements use one or the other; using both captures the organism's complete output — including its β-(1,3) and β-(1,6)-D glucan polysaccharides and 30 mg of declared mannans per serving.
THE CELL WALL DISRUPTION METHOD
Mushroom cell walls are built of chitin — the same tough material as insect exoskeletons — and much of a raw mushroom's content passes through undigested. A patented mechanical process breaks that scaffolding without heat or harsh chemicals, releasing the water-insoluble glucans that conventional powders leave locked inside.
ANCHORED BY FOLATE
Folic acid at 62.5 µg per serving carries the authorised claims: folate contributes to the normal function of the immune system, to normal blood formation, and to the reduction of tiredness and fatigue. A small amount of ginkgo leaf completes the East Asian botanical heritage. Made in Japan.
