Hey Japanese people.
So you guys are already contaminated with the radiation?
Isn't it just scary?
Well I'm guessing that devastating earthquake is going to
hit Tokyo and kill a lot of people,
which I really can't wait for it.
I'm always thinking Japanese people dying, but I can't kill them
directly, so it was really exciting to hear that Japanese people are
dying from the natural disaster.
Well, im going to stop here and watch Japanese suffer more from
the earthquake.
Hope you guys die soon.

To the Japanese here it is very rude that you say you didn't do anything wrong. here is alist of countries that were attacked, invaded or occupied by Japan in WWII. In roughly chronological order.

The war began with Japanese expansion in China (1937). Japan eventually opened up three fronts:

China
Soviet Union
Mongolia

Vichy France agreed to the Japanese occupation of French Indochina.

Vietnam
Cambodia
Laos

The United States, concerned with Japan's rapid expansion, implemented a complete oil embargo on Japan. At the time 80% of Japan's oil came from the US. Japan decided to make a quick grab for all of Asia to secure more resources. They attacked numerous countries almost simultaneously:

United States
Malaysia (UK)
Singapore
Hong Kong (UK)
Dutch East Indies (Indonesia)
Timor (Portugal)

Thailand became an ally of Japan under threat. During the course of the war Japan also attacked or invaded:

Australia by sea
New Zealand by sea
Burma (Myanmar )
India
British New Guinea (Papua)
The Philippines
Andaman and Nicobar Islands (India)
Straits Settlements (Singapore)
Brunei (UK)
Nauru (Australia)
Guam (USA)
Imphal (India)
Wake Island (USA)
Gilbert and Ellice Islands (UK)
Christmas island (Australia)

Japan occupied Manchuria, Taiwan and Korea from before the outbreak of WWII.

As you can see Japan has used unit 731 on most of these countries and they killed and were brutal to many of the people here. It is very rude for you to pin point every problem south korea has.
