difference between particle ni and he

Hello everybody! Konnichiwa!

I can't catch the difference between the two "move to" particles に and へ.
By the moment I am using them in my sentences without a specific rule.

I know that somebody out there would help me!!
Ex:
watashi wa Toukyou ni ikimashita OR Toukyou e ikimashita???

Doumo arigatou!

When you are talking about "going to (someplace)," then "ni" and "e" are almost interchangeable.

To say "I went to Tokyo," you can say:
- Toukyou ni ikimashita
and
- Toukyou e ikimashita.

The slight difference is "ni" pinpoints a destination, and "e" is more "in the direction of," or "toward...."


They are not exactly the same in other meanings, of course.
When you talk about "movement into/onto something/some place," then you use "ni."
For example:
- O-furo ni hairimasu. (I get into the bath.)
- Densha ni norimasu. (I get on the train.)

You will come across different meanings/usages of those particles, such as:
- Roku-ji ni okimasu. (I get up at six.) time
- Kaimono ni ikimasu. (I go for shopping.) purpose
- Eiga wo mi ni ikimasu. (I go to watch a movie.) purpose
- Heya ni tsukue ga arimasu. (There is a desk in the room.) location

...but you will encounter these gradually :)

To add to the post above, "he" doesn't seem to be as often used. At least, I don't hear it very often. It is definitely a yet productive particle, but I wouldn't be surprised if it disappeared some time in the future...

Finally I have understood the use of these particles.
The explanation is very clear.
So if I don't want to use always NI I can use E with cities and countries (Tokyo, Osaka, Rome, Milan...) and NI when I want to specify that I have to enter in the place I am going to (ex. a shop, a school, the pool etc...)
