Most brands sprinkle twenty things in milligram pinches. Nutroko puts four things in at full measure: grams, not milligrams. Of the ten grams, 5,000mg is mushroom fruiting body.

Batch 001's matcha base powder is tested by SUNATEC, an independent Japanese food analysis center. The 200-item pesticide screen came back "none detected". Heavy metals, mycotoxins, and microbial counts are tested too.

Pre-order at the founding priceThis is a pre-order: Batch 001 ships August 25 from Osaki-cho. Change your mind before it ships and we refund in full.
Nutroko is a matcha supplement (a Japanese mushroom matcha), mixed as a morning cup. One pouch is thirty mornings. We're not asking you to quit coffee. We're asking for the first cup.
One small run, weighed and sealed by hand in Osaki-cho, at the same local factory that makes our sweet potato powder. The batch in this photo is the one that ships in August.
No warehouse, no thousand-unit run. When Batch 001 is gone, Batch 002 is the next chance, at a higher price.
The honest part, before you find it yourself: we have zero reviews. You'd be among the first. What we can offer instead is everything you can check — a real company in Osaki-cho, Kagoshima, a town of eleven thousand; a founder with his name and face on this site; the recipe in grams; third-party results from SUNATEC; and a batch packed by hand. He answers every order email himself.





August 2026, from Osaki-cho. Batch 001 is a single hand-packed run; pouches are allocated in the order reservations arrive. You'll get a shipping confirmation by email when yours is on its way.
Four things. Every 10g cup holds matcha 3g, lion's mane fruiting body 3g, cordyceps militaris fruiting body 2g, and Kagoshima sweet potato powder 2g: 5,000mg of mushroom fruiting body per cup. The full recipe is printed on the front of the pouch, in grams.
One pouch is thirty mornings. What the price pays for: 5,000mg of mushroom fruiting body per cup, four ingredients and nothing else, third-party testing of every batch, and a run packed by hand in Osaki-cho. We'd rather show you the arithmetic than tell you a story, and we never discount or run sales.
We won't ask you to. Instead we show you things you can check: a real company in Osaki-cho, Kagoshima, a founder with his name and face on this site, the recipe in grams, third-party results from SUNATEC, and a batch packed by hand. Reviews will appear here as real customers write them, good and bad, published as written.
A proper Kagoshima matcha: grassy, a little sweet, and it takes milk well. The lion's mane and cordyceps are finely milled fruiting-body powders; the cup tastes like matcha, not mushrooms. Fair warning before you buy: it's an earthy matcha latte, not a dessert.
You order today through our secure Shopify checkout: the monthly subscription at ¥6,500 a month, or a single pouch at ¥8,500. Batch 001 ships in August; if your plans change before it ships, reply to any email and we refund in full, no questions asked.
Because a hand-packed batch only goes so far. Rather than sell past what we can pack, every pouch is allocated to a reservation in the order it arrives. When the batch is spoken for, orders close until Batch 002, at the Batch 002 price.
¥6,500 a month is the founding subscription rate, Batch 001 only, and it stays yours for life while you're in. Later batches open at a higher rate, and a single pouch is ¥8,500. We price Nutroko like specialty food, never discount it, and never run sales. Ordering earlier is the only way to pay less.
Because Nutroko is made to be drunk every morning, and the subscription is priced for that. One pouch alone at ¥8,500 is there if you want it (¥283 a morning, still about half a café habit), but the founding subscription is the price we want you to have.
Batch 001 ships Japan-domestic only. International shipping opens with Batch 002 in September 2026. You can reserve from anywhere; if you're outside Japan we'll hold your founding price for Batch 002 instead.
