The first sentence of Professor Murase’s article “The Most-Favored-Nation Treatment in Japan’s Treaty Practice During the Period 1854-1905” which appeared in the April issue of the Journal is incorrect. He asserts that “[i]t can be said today that a unilateral most-favored-nation (MFN) clause is only of historical significance.” However, even today, Japan lives under the threat of a unilateral unconditional most-favored-nation clause.
