Korea: Average of 7 reported/platform prices (ranges taken at midpoint; mix of lowest prices and prices incl. consultation). Japan: Average of 8 clinics' official prices (consultation included at 4, extra at 2, unstated at 2).

Some clinics lowered self-pay prices in Aug–Sep (e.g. Tams Toyocho 2.5mg ¥17,600→¥12,800, Tifa Yokohama ¥18,800→¥15,800); others kept per-pen prices.
