Kijunchi’s Health Number Checkers
A Japanese browser-based tool for interpreting health-checkup, blood-donation, and body-composition measurements against published reference ranges.
Field notes
The site organizes several Japanese health-reference workflows around forms rather than a general article library. Users can choose between Japan Human Dock and specific-health-check classification schemes, leave unknown measurements blank, and print the resulting reference information. Linked tools extend the same approach to blood-donation reports covering 15 items and body-composition readings covering six measurements. The page says processing remains in the browser, while repeatedly separating reference comparisons from medical diagnosis.
