The track record of the Judeo-Christian God as shown in the Bible shows that JCGod punishes other people who attack his chosen people (Hebrews) or try to convert them. JCGod also punishes his chosen people (Hebrews) for turning away from him.
The JCGod also protects the land he promised to his people or he takes it away from them.
Japan doesn't fall into any of these categories that I know of.
The JCGod is not punishing Japan. The planet just does what it does. Natural disaster with no intent behind it.
Although I can see why ancient people would feel that their gods (nature) had turned against them when such a disaster happened.
