To learn Japanese, consider finding a language tutor or class, which is often the most effective way to begin learning.  You may also try using a language tutor app such as Duolingo or Rosetta Stone.  Another option would be to start by finding a word list of common words, and practice memorizing those translations, pronunciation, and writing.  As Japanese has three different writing systems which may be difficult for native English speakers, you may wish to start with verbal practice before tackling reading and writing.
