The Japanese can just camp at the straits and take them out.

Even at Gibraltar, guarded by the British and another narrow strait, German subs managed to sneak past and into the Mediterranean. Against 1945 German subs, it is hard to believe the Japanese, with their relatively weak ASW prowess, would prevail. If a battle is forced, a likely outcome may well be the destruction of Japan's ASW ship barrier, followed by a blockade of Singapore.
