There are tens of thousands of earthquakes in Japan each year; without reference to a particular earthquake, the question cannot even be approached.
However, even with reference to a particular earthquake, the answer would vary widely, depending on the operational definition of "saved" employed. At the crudest, one could define "saved" as "not killed or injured." This would mean that all of the people were saved in nearly every earthquake.
Furthermore, earthquakes per se are generally not dangerous for most people (although the sudden onset of most earthquakes could cause damaging or fatal stress in those with heart problems): most of the danger to people comes from collapsing structures or from the secondary effects of phenomena like tsunami caused by earthquakes.

It is estimated that around 200,000 people were left homeless after the 1906 San Francisco earthquake. Many were forced to live in makeshift shelters and refugee camps until they could find more permanent housing solutions.
It is difficult to provide an exact number as it varies, but thousands of people were left homeless as a result of the Japanese earthquake. The government, along with various organizations, worked to provide shelters and support for those affected by the disaster.
