What it is

ist315.com is the official website of ist Co., Ltd. (イスト), a Japanese agricultural product processing company founded in 2007. It mainly supplies deep-processed ingredients made from domestic Japanese vegetables, and also provides end-to-end OEM development services covering everything from functional foods to daily chemical products. Its star core product is a domestic onion skin processed ingredient rich in quercetin.

Core Offerings and Positioning

The brand serves B2B clients with three core categories of products:

1. Functional food ingredients, centered on powder, flake, and tea bag ingredients made from 100% domestic Japanese onion skin, alongside other agricultural ingredients like burdock powder;
2. Finished food development, covering onion snacks, dried fruit, jam, pet food, and more;
3. Eco-friendly daily chemical products, including safe alkaline electrolyzed water and disinfectant cleaning products.

It also offers full-process OEM customization services from demand research and product design to quality control and mass production.

Pros, Cons, and Ideal Use Cases

Its strengths include clear ingredient traceability, strict quality control, a focus on natural no-additive formulations, R&D collaboration with Tokyo University of Agriculture, and clear differentiated positioning that aligns well with current demand for healthy functional food development. However, its drawbacks are also obvious: it only serves B2B clients and does not support individual purchases, there is no Chinese language interface, it has a high entry barrier for domestic Chinese users, and pricing is not transparent. This website is best suited for Chinese food and health supplement companies that need to source imported Japanese functional ingredients and partner for Japanese OEM development services.

Accessibility from China

The website can currently be accessed directly and normally without a proxy. However, the entire site is only available in Japanese with no Chinese language option, business negotiations require Japanese proficiency, and it does not support the payment and procurement processes commonly used in China.
