The Governor-general Makoto Saitoh enthusiastically proceeded Korea election civil right movement in 1930 which had juxtaposing relationship with those movement brought up in Irish Free State(1921). What sort of political and international surroundings were there around Governor-general Saitoh to make its decision? Why did this policy stop before the half way? I observe the reason on the ground of Shidehara & Uchida diplomacy.
