What are Apostille and Legalization?
Both Apostille and Legalization are the processes where government authenticates that a public document was written by who put signature and stamp on it.
There are 2 ways to authenticate public document to be submitted to foreign institute, Apostille and Legalization. Submitter of public documents select Apostille or Legalization considering whether the country to receive the document is a member of Treaty of The Hague or not.
More specifically:
when the country to receive the document is a member of Treaty of The Hague, submitter has to select Apostille; and
when the country to receive the document is NOT a member of Treaty of The Hague, submitter has to select Legalization.

In Japan, authentication is not frequently required because Japan has the system of registration of seal impression. This is that, in Japan, when a document has the seal of the issuer on it, it can be officially recognized that the document has been issued by the owner of the seal.
On the other hand, system of registration of seal impression is not so popular in many countries. Therefore, authentication of document is widely adopted in many countries to identify issuer of the document and the owner of the seal/signature put on the document.
Extra Info.
Treaty of The Hague is a name of cluster of plural treaties. Treaty of The Hague includes "Convention Abolishing the Requirement of Legalisation for Foreign Public Documents", which allows the member countries of the treaty to authenticate public documents with an easy process called Apostille.
You can check the list of the member countries of Treaty of The Hague in the WEB site of Ministry of Foreign Affairs of Japan.

As a side note, the meaning of "authentication of private document" and "certificate of seal impression of notary" are as follows.

The system where a notary certifies that the signer and the writer of the document is same person. - Certificate of seal impression of notary:
