Look up the official Japanese health-insurance (NHI) price of a drug as the Ministry of Health, Labour and Welfare (MHLW, 厚生労働省) publishes it in the list of drugs covered by insurance (薬価基準収載品目リスト): brand name, active ingredient, specification and unit (the price is per that unit), manufacturer, NHI price in yen, whether the product is an originator (先発品), a generic (後発品) or a quasi-originator (準先発品), whether the generic is eligible for add-on payment, the list code (the 12-character drug price list / YJ code), listing and transitional-period notes, and the date the current edition applies from. Categories: oral (内用薬), injection (注射薬), external (外用薬), dental (歯科用薬剤); only the categories asked for are read. The list is Japanese with no Latin ingredient names: search with the katakana or kanji brand or ingredient (キイトルーダ, アムロジピン, 武田薬品), words are ANDed and full/half width and hiragana/katakana are folded, or pass the 12-character code. Every answer states the list edition and its applies-from date; a zero-match answer says which categories were searched. Example: query=“キイトルーダ”, category=“injection”.
