Operator and author
西川貴徳 is responsible for MIZUIROWorks and writes and edits Ne9 product information and articles on this website.
These articles are published by the business developing the product, not by an independent reviewer. We distinguish our own planned specifications from general guidance published by public authorities.
Why a pouch?
Ne9 is being developed as confectionery powder sealed in non-woven fabric for situations where handling a drink is inconvenient. Our aim is to explain the format, amounts, taste and use clearly before purchase.

Editorial policy
We link factual claims to primary references, distinguish overseas assessments from Japanese requirements, and check product details, wording and sources before publication, including when writing-assistance tools are used. We update the revision date after content changes and investigate corrections reported by readers. General caffeine guidance does not certify Ne9's safety or regulatory status.
