How much medicine can you bring without paperwork?
Most travelers may carry up to a one-month supply of prescription medicine and a two-month supply of over-the-counter drugs into Japan without any advance paperwork. Quantities are counted per medicine, not per traveler. [1]
Which medicines are banned in Japan?
Some products sold freely elsewhere are prohibited in Japan, including medicines that contain amphetamine or methamphetamine (such as Adderall), which cannot be brought in under any circumstances. Cold and sinus medicines containing more than 10% pseudoephedrine or ephedrine are controlled as stimulants' raw materials and cannot be brought in without advance permission. [2] Having a foreign prescription does not exempt you, so check the ingredient list before you pack. [1]

When do you need a Yakkan Shoumei?
Above those limits you must obtain a Yakkan Shoumei (import confirmation certificate) from a Regional Bureau of Health and Welfare before you travel. Self-injection medicines such as insulin pens and pre-filled syringes follow the same rule: up to a one-month supply needs no certificate. The certificate is normally issued within a few business days of a complete online application, so applying about two weeks ahead leaves room for corrections. [1] Narcotics such as morphine or oxycodone, and stimulants' raw materials such as lisdexamfetamine (Vyvanse), are not covered by the Yakkan Shoumei: they need a separate permit from the Narcotics Control Department, which asks you to apply at least 14 days before travel. [1]
Also carry something that shows exactly what you take, such as a copy of the prescription, a doctor's letter or your medication record, so that a doctor in Japan can prescribe the same medicine if you run out or your stay is extended. See Continuing your medication in Japan.
