[emoji] 面白い話です。私は日本語を習い始める時、日本語の「ふ」って聞き難しかったですね。

There is no "F" sound of F in these words, huton, kakebuton and shikibuton. Despite most of Japanese people can't not being able to pronounce F properly, it is introduced as known by "futon" to all over the world.

I became speechless to know couldn't believe it when I learned that there are some people who don't know that "futon" is a Japanese word. Moreover, what surprised me the most is that what they consider to be futon they think is not the same as Japanese ones.
He showed me and said, "It's a futon in my country."
It was a sofa bed. How could it is it supposed to transform?

Chizuko-san, this notebook entry was loads of fun . . . or should that be hun?

Futon vs Huton ふとん対戦2017

Very good story!

* Who is "he"? This is a funny story, but stories make more sense if they have context. ("The futon salesman corrected me" "my English tutor corrected me" "an irritating delivery man corrected me")

By the way, British English and US English have different rules about whether the period or comma should go inside the quotation marks or outside. The American rule is that comma always goes inside the quote (when I said "huton," he corrected me) and so does the period (the autocorrect shows "futon.") 

** I became speechless - Hmm. I don't know why, but "I was speechless" usually goes at the end of a statement. ("When I learned that there were people who didn't know 'futon' was a Japanese word, I was speechless"). But at the beginning of a sentence, instead of "speechless," it would be more natural to use "stunned," "shocked," or "dumbfounded." ("I was shocked to learn that there are people who don't know 'futon' is a Japanese word!") "Dumbfounded," by the way, has the same meaning as "speechless."

Notice that in my examples above, one time I used past tense ("there were people") and the other time I used present tense ("there are people.") I think both are correct, it's a matter of choice and style.

The reason for the fu-hu confusion (conhusion???) is that the Japanese "hu" syllable is pronounced with the lips making a small circle, with the lower lip pulled slightly in. The English "hu" sound is made with the lips much more open, and the air flowing more freely. The English "f" sound is made by flicking the lower lip against the upper teeth. So to English speakers, the Japanese "hu" sounds more like an English "fu" so when Westerners write Japanese syllables in Roman letters, they write ha-hi-fu-he-ho!

The word, "huton" or "futon", whichever it is, it means a kind of Japanese bedclothes. They are made from a lot of stuffed cotton or feathers and have two types of usages. One is for covering your body when you sleep and it keeps you warm. It's called kakebuton. The other is called shikibuton, which is for your lying down on it. It looks like a mattress.
There areis no sound of F in these words, huton, kakebuton and shikibuton. Despite most of Japanese people can't pronounce F properly, it is introduced as "futon" to all over the world.

This is a Japanese futon.
