Natural Kitchen Co., Ltd. | Protein Drinks / Green Juice (Aojiru)OEM Manufacturing (Tokyo)

Editorial Notes

Headquartered in Minato, Tokyo and operating a GMP-certified in-house plant in Izu, Shizuoka, the company focuses squarely on contract manufacturing of protein powders, aojiru green-juice drinks and supplements. The editorial view is that its strength lies in owning the full chain in one place: powder processing, filling and packaging, and quality inspection are handled internally, while recipe design, package design, production and delivery are wrapped into a single-window workflow. Combining this with third-party laboratory testing gives buyers a defensible quality story for a category where substantiation matters. The manufacturer fits D2C brands and wellness-oriented buyers who want to launch protein, greens or powdered supplement SKUs from small runs, and who value being able to iterate across tablet, capsule and powder formats without switching suppliers. It also suits merchandising teams that need parallel prototyping of multiple recipes rather than long single-SKU production lines. On the practical side, minimum order quantities and standard lead times are not publicly disclosed, so buyers should expect terms to shift with ingredient availability and packaging spec, and engage early. Certification is scoped to health-food GMP rather than broader food-safety schemes, positioning the company as a mid-tier domestic powder-focused OEM whose edge is planning support plus a Japan-based owned facility.
