    "Alcohol is assessed by volume: 3 bottles × 760 ml = 2280 ml per adult. If you give only a bottle count, each bottle is assumed to be 760 ml. When drinks of different types exceed the allowance, the allowance is applied to the highest-rate drink first (Customs chooses in the traveler's favor).",
    "Heat-not-burn: 10 individual packages = 200 sticks (IQOS / glo, 20 per pack) or 50 capsules (Ploom TECH / with type, 5 per pack), per Japan Customs' own examples.",
    "More than one kind of tobacco: the English rule says the total allowance is 250 g. For that reading we use cigarette ≈ 1 g, cigar ≈ 5 g, heat-not-burn stick ≈ 1 g, heat-not-burn capsule ≈ 4 g (one pack ≈ 20 cigarettes), cap each kind at its single-kind allowance, and use the 250 g on cigars / other tobacco first, then cigarettes and sticks, then capsules. Japan Customs' own worked example (zeigaku.htm) instead exempts only the one most favorable kind in full and taxes the rest, so the high estimate uses that stricter reading.",
    "Perfume: 2 oz ≈ 56 ml (1 oz ≈ 28 ml). Eau de toilette and eau de cologne are not counted as perfume (menzei.htm).",
    "Other goods: a line (one kind of item) whose total overseas value is ¥10,000 or less is free and not counted (menzei.htm: 1品目ごとの合計額が1万円以下). Each article worth more than ¥200,000 is fully dutiable. The ¥200,000 is then filled with the articles that save the most duty (best-subset search).",
    "Customs value = overseas retail price × 0.6 (zeigaku.htm). Simplified 15% applies to that Customs value; articles whose Customs value exceeds ¥100,000 (overseas price above about ¥166,667) use the general tariff and are not estimated. Duty-free-tariff articles (wristwatches, golf clubs, PCs, loose gemstones, paintings) pay 10% consumption tax only.",
    "Rounding follows the official example: yen are truncated per line, then each tax type (liquor tax, tobacco tax, customs duty, consumption tax) is truncated to ¥100; the consumption tax base is truncated to ¥1,000.",
    "travelers multiplies the per-person allowance and assumes everyone is in the same age band; articles are pooled. Run minors separately for an exact split."
