Is 500 ml or 1 L a Reihaku batch code?
No. It is the container volume.
Check Reihaku Cosmetic Batch Code
Reihaku (麗白) is Kumano Yushi's Japanese Hatomugi skin- and body-care brand. The range includes 500 ml and 1 L lotions, 300 ml emulsions and gels, 400 ml body milk, cleansers, face wash, body wash and refill pouches. Hatomugi, medicated, fragrance-free and bottle-size wording identifies the formula or pack—not a batch.
Reihaku FAQ
Where is the mark on a Reihaku refill?
Check the top and bottom heat seals and the area around the pour spout.
Can I use a Naturie Hatomugi code in this cosmetic context?
No. Reihaku is a Kumano Yushi brand; Naturie is a different product line and manufacturer.
Reihaku marks on Hatomugi bottles, pumps and refill pouches
Before you rely on the decoded date
- Inspect large bottles and pump containers at the moulded base, shoulder and back label. On a refill pouch, check both heat-sealed edges and the area near the spout; on tubes, inspect the crimp, and on jars the underside.
- Keep Reihaku separate from Naturie Hatomugi and other job's-tears products. Confirm 麗白 and Kumano Yushi, then ignore the JAN barcode, 500 ml/1 L volume and product number when choosing the production mark.
Common lookup mistakes
- Photograph bottle and refill together only if they came from the same purchase, and enter the mark from the package that actually held the formula.
- A faint short inkjet string can sit close to dense Japanese legal copy, so use angled light rather than relying on the prominent numeric barcode.
