Hana's grandmother planted a grove of Phyllostachys edulis in Itoshima in 1958. She called it Aiko - "loved child" - and every year she'd cut a single culm to make the next year's tea-room ladle.

We've inherited Aiko. We don't make ladles. We do, however, cut the culms at four years (industry default: eight), spin the fibre into a fine viscose, and knit it into the softest underwear we know how to make.

One stalk yields about twelve pairs. Aiko gives us roughly four hundred stalks a year. That's the whole catalog. When we sell out, we sell out - and then we wait for the rain.

Slow goods. From one grove. Made on purpose.
