Revision of the foreign price adjustment and repricing system

Published:
In the FY2026 revision, a change was made to reflect weighted averages based on domestic market share in country-specific prices. However, there has been no progress toward abolishing the foreign price repricing system, and concerns remain that substantial price reductions may lead to unprofitability and supply discontinuation. This revision did not itself achieve a reduction in the maximum price reduction rate.

Recommendations

  • Verify the impact of the revised calculation method on reimbursement prices and stable supply.
  • Consider abolishing the foreign price repricing system, or limiting foreign price adjustment to a single instance at the time of new listing.
  • If these measures prove difficult, review the outlier exclusion rules and the maximum price reduction rate to maintain the comparison level.
  • Design the system so that it does not undermine the continued supply of necessary products, taking into account differences in domestic and overseas distribution structures, exchange rate fluctuations and supply costs.
