四つの素材·The formula

Four ingredients. Ten grams.
Nothing else.

Most blends sprinkle twenty things in milligram pinches. Nutroko puts four things in at full dose: grams, not milligrams, the amounts the published research used. Both mushrooms are whole fruiting body, not mycelium on grain.

大崎町·Our founding story

The coffee alternative from the Kagoshima countryside.

A small town by the sea

Osaki-cho, Kagoshima. Population about eleven thousand, and shrinking. Tea has grown on these fields for generations.

How Minami ended up here

Minami came to Japan to play professional volleyball. When that career faltered, he found a new purpose in this shrinking town: working the farms, learning the tea, and mixing the first pouches of Nutroko.

Every pouch keeps the town going

The matcha is grown here, bought direct from the farmers we know. Every pouch ships from this town, and keeps a little more of it going.

Batch 001, packed by hand

The first batch, weighed and sealed by hand in a food-grade kitchen in Kagoshima — the pouches in this photo are the ones that ship in August. When they're gone, Batch 002 comes at a higher price.

Questions, answered plainly.

When does Batch 001 ship?

August 2026, from Osaki-cho. Batch 001 is one small first batch; reservations are filled in the order they arrive. You'll get a payment link by email when your pouch is ready to ship.

Does it have caffeine?

Yes, the caffeine that's naturally in 3g of matcha, nothing added. Matcha's caffeine arrives alongside L-theanine, so the curve is gentler than coffee's spike. Exact per-cup figures publish with Batch 001's lab results; we'd rather show you the certificate than guess a number.

What does it taste like?

A proper Kagoshima matcha latte: 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.

How does pre-ordering work?

You reserve a pouch today with just your email. When Batch 001 ships in August, we email you a payment link for ¥6,500 per pouch. If your plans change before then, reply to any email and we release your pouch, no questions.

Why does the price go up after Batch 001?

¥6,500 is the founding price for the first batch only. From Batch 002, Nutroko is ¥8,000+. We price it like specialty food, not like supplements, and we never discount, so the founding price is simply the earliest price, not a sale.

Do you ship outside Japan?

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.
