It was our visit ato The Tono Museum, in the North of Japan.

"Visit" here seems like a verb, so it needs "to" after it so it can connect with the rest of the information.

This museum is the first jJapanese museum dedicated to the folklore, thaand it was opened in 1980.

I love learning about the tales of different countries.

Since it's a habit, something you do often, it should be learnING.
(examples: I learn a language. I learned a language. I'm learning a language. I love learning languages.)

It was a little town really pretty little town, with old and traditional jJapanese houses, in the middle of nowhere.

Saying your previous sentence out loud would be fine and casual. "Really pretty" in your sentence, when spoken, would be like a side comment. In writing, however, it doesn't work.

Tono is the town ofhome of the Kappa, a strange creature who looks like a turtle,. They're not reactually friendly, because they eat little children if they approach rivers.

"Home of the ___" is a common phrase. (It appears in the American national anthem: "For the land of the free and the home of the brave".)

ButHowever, they also help pregnant women.

Starting a sentence with "but" in English writing isn't technically correct, though it's fine in speech.

Strange duality, noright?

Ending a sentence with "no" like this isn't wrong necessarily, but I wouldn't say it's common. People will understand, so you can say it if you like.

I don't know why, but I felt good there, maybe because of the good energy.

We met a group of children, around eight, who were playing, and w. When they saw us, they all said "Hello!" with a big smile.

The sentence is a bit long and uses lots of commas. It would be better to split it into two.

Apparently, they were too much old forto be scared of the Kappa.

Concerning the museum, we can saw a lot of different myths and legends about Japan.

Of course, everything was in Japanese, but tit was fine. Thank you Google Translate!

The museum was not realln't very big, but we cfould find some interesting interactives expositionhibits.

"Expositions" and "exhibits" might mean the same thing technically, but "exposition" sounds very grand and formal. At a museum, there are "exhibits".

I passedspent a lot of time just opening books and looking at the illustrations.

Because, obviously, I couldn't read jJapanese.

Starting a sentence with "because", much like starting a sentence with "but" isn't technically correct when writing in English. You can combine this with the previous sentence.

After that, we visited a traditionnal house conserved by the museum.

It was the house of Kunio Yanagita, the foundatoer of folklore ethnology in Japan.

He wrote the Tôno Monogatari in 1910, the most important work about jJapanese folklore.

I had a real interest for this personality, but he sadly had a link with a political party that I don't share the ideasagree with.

In conclusion, if you will go invisit this part of Japan, you definitely need to go there!
