Hello, I am Yoshi from NILS Japanese language school. Let’s learn Japanese language with us together!
[ここ／そこ／あそこ／こちら／そちら／あちら]
The demonstratives これ、それ and あれ that are discussed in Lesson 2 refer to a thing, while ここ、そこ and あそこ refer to a place.
ここ is the place where the speaker is.
そこ is the place where the listener is.
あそこ is the place far from both the speaker and the listener.

こちら、そちら and あちら are demostrative words, referring to direction. こちら、そちら and あちら are also used to refer the location, in which case, they are politer than ここ、そこ and あそこ.

*When the speaker regards the listener as sharing his/her territory, the place where they both are is designated by the word ここ. Under this situation, そこ designates the place a little distant from the speaker and listener, and あそこ designates and evene more distant location.
