Those are immunization impressions. You never got shot in the arm as a kid?

BCG Tuberculosis Vaccine

Not every country requires children be vaccinated against TB, and different countries use different delivery methods. BCG vaccine must be delivered only into the skin, not into the muscle, and so in Japan they use a device to sort of scratch it on to kids' upper arms. The "Stamp Syringe" スタンプ注射 marks essentially double as proof of vaccination.
