Hi! I haven’t posted in a while! So, Here are some good
japanese words and phrases to know:

Chikatetsu=subway
Wa= Is, as for, regarding to
Koko=here
Doko=there
Conbini=convienience store
watashi=I
janaidesu=not
desu= pronoun, commonly used, at the end of a sentence due to japanese grammer
Sumaho=smartphone
iie=no
hai=yes
doko=there
ka=word indicating question, at the end

With words like this, you can say things like
