Let me introduce a Japanese manga for those who love classical music.

It's title is"Piano no Mori," written by a female cartoonist, Makoto Issiki.

The story is about young persons\people competing in the International Chopin Piano Competition held in Warsaw, Poland.

We Japanese like to listen to the piano music and in particular Chopin's works.

A Japanese, Ayako Uehara, won the Piano Award of the International Tchaikovsky Competition in 2002.

In fact, a former pianist, Sosuke Ajino, had abandoned the piano before.

Kai was eagerly asked by Ajino to participate in it.

However, Kai attracted the audiences with his dynamic performance and received a thunder of applause.

Can either of the two\both the Japanese win in spite of formidable enemies?

Its title (or the title) is "Piano no mori", written by a female cartoonist, Makoto Issiki.

It is very interesting and inspiring.

It started in 1998 and has been regularly published in a comic magazine.

However, no Japanese have won the Chopin Competition. let's use "have never won" if there's no more Chopin Competition held in the future.

Shuhei is the son of a distinguished pianist and set out to become a professional pianist. *) distinguished = successful and commanding great respect, noble and dignified in appearance.

Later, he was transferred to an elementary school and met a boy, who is called Kai.

Before long, a Mozart piano competition would be held there.

He accepted the offer though he was reluctant because he had never done any public performance before.

However, Kai attracted the audiences with his dynamic performance and received a great standing ovation. *) thunder of applause is OK

Shuhei was 16 years old when he came back to Japan after 4 years.

He came back to Japan for the first time in four years.

He looked for Kai who was out of contact because he wondered if Kai kept playing the piano.

As soon as Shuhei was relieved to hear Kai still playing, soon he returned to Vienna.

Kai suddenly appeared in a competition in Kyushu.

He won and got a chance to take part in the Chopin Competition the following year.

Shuhei was surprised to hear the news since he intended to participate in it the year after next.

On second thought, Shuhei resolved to partake in the following year's Chopin Competition because he wanted to beat Kai this time around.

It started in 1998 and has been serialized in a comic magazine.

A Japanese person, Ayako Uehara, won the Piano Award of the International Tchaikovsky Competition in 2002. (to me, "a Japanese" by itself sounds strange, and possibly racist. But there are also many people who don't think so. Perhaps it's a British thing...?)

However, no Japanese person has ever won the Chopin Competition.

Shuhei is the son of a prestigious pianist and set out to become a professional pianist. (prestigious or distinguished are both ok)

Kai grew up while playing the piano without any teachers.

Surprisingly, the keys were too heavy for Shuhei to make a sound.

He was surprised to see Kai playing it, because the keys were so heavy that nobody else could strike a note.

Shuhei naturally took part in the competition and seemed likely to win.

He had never perfomed in public, but accepted reluctantly.

However, Kai attracted / enthralled the audiences with his dynamic performance and received a thunder of applause.

When Shuhei was 16 years old he came back to Japan for the first time in four years.

He looked for Kai who was out of contact because he wondered if he had kept playing the piano.

Shuhei was relieved to hear that Kai was still playing, and returned to Vienna.

He won, and therefore had the right to take part in the Chopin Competition the following year.

On second thought, Shuhei resolved to participate the following year because he wanted to beat Kai this time around. (? but he beat him the first time)

The serialization of the comic magazine has continued and the 21st volume of the comic is going to be published this month.

The first and the second qualifying round (of the Chopin Competition?) have finished and the final round has started recently.

Shuhei and Kai compete against such rivals as Korean twins, a Chinese person from a poor section and a Polish person, Lev Simonovsky, who is the favorite.

Even though you aren't Japanese, it's still really impressing since it is a tale about friendship and rivalry.

It's much more interesting than the best seller manga, "Nodame Cantabile."

I once read an English bootleg of the comic on the Internet.

We Japanese like to listen to piano composed music. and in particular Chopin's work in particular. [I made it into 2 sentences because it flows better. Sounds more natural ]

Shuhei is the son of a prestigious distinguished pianist and who sets out to become a professional pianist himself. OR "Shuhei is the son of a prestigious distinguished pianist and who sets out to become a professional pianist in his own right*." (*in his own right = by reason of one's own ability or ownership etc.; Example:"she's a rich woman in her own right rather than by inheritance"; "an excellent novel in its own right" *in her own right, in its own right, in one's own right* <--other ways to use that phrase)

He was surprised to see Kai playing it because the keyboards were so heavy. that Anyone else could not even strike a note.

He accepted the offer though reluctant to do so, for he had never performed in public before. but accepted although he was reluctant. [ I could be wrong with the placement of the comma (*-*) ]

He looked for Kai whom he was had been out of contact with and because he wondered if Kai kept continued playing the piano.

As soon as Shuhei was relieved to hear Kai still playing so he then returned to Vienna.

He won and got the right had an opportunity to take part in the Chopin Competition the following year.

On second After some thought, Shuhei resolved decided to partake the following year because he wanted to beat Kai this time around. [ "on second thought" sounds weird to me. I could be wrong but it makes more sense when it's more of an "a-ha!" moment.]

The serialization publication of the comic magazine has lasted 13 years (1998-present), and the 21st volume of the comics is going to be published this month. [ I added the number of years because when one write " {word} has lasted..." one adds the time period this {word} has been occurring]

Shuhei and Kai competes against such rivals as: Korean twins, a Chinese from a poor section and a Polish, Lev Simonovsky, who is the favorite.[Colons--> : <--- are used when you are listing something]

Shuhei's psychology is particularly depicted in details.

"Piano no Mori" is translated in Traditional Chinese and also published in Taiwan.

"classical music" is correct.

It is titled "Piano no Mori,"and is the work of a female cartoonist, Makoto Issiki. >I don't like "written" here because manga are also "drawn". Let's avoid the problem this way.

A Japanese woman, Ayako Uehara... >surely this is not sexist, is it?

However, no Japanese pianist has ever won the Chopin Competition.

He transferred to a new school and met a boy called Kai.

Surprisingly, the keyboard action was too heavy for Shuhei to make a sound.

A Mozart piano competition was going to be held there soon.

Kai was strongly urged by Ajino to participate in it.

However, Kai captivated the audience with his dynamic performance and received thunderous applause.

Shuhei was filled with a sense of defeat and left for Vienna to take lessons from a (famous?) teacher. >I'm not sure exactly what you mean by "authentic". The word might make sense in certain contexts, but I'm not sure it applies here.

He had been out of touch with Kai, and looked for him because he wondered if he had continued playing the piano.

Kai was taking lessons from Ajino, and working as a musician at a strip show.

Shuhei was relieved to hear that Kai was still playing, and he returned to Vienna.

Shuhei was surprised to hear the news since he intended to participate in it the following year.

"Participate"is the correct word. "Partake" has a different meaning.

Even if you aren't Japanese, this should still be really impressive since it is a tale about friendship and rivalry.

In particular, Shuhei's psychology is depicted in detail.

These are the first five pieces from Etudes Op.10 composed by Chopin and performed by Nobuyuki Tsujii at the Cliburn Competition Preliminary Round in 2009.

We Japanese like to listen to piano music, Chopin's works, in particular. (Should be one sentence instead of sentence fragments.) Also, if you say "the piano music" it means "piano music from this work/manga/anime" and if you say "piano music" (without "the") it means "music played on piano, in general." So the meaning is a little different. I'm thinking you meant in general, but I can't tell.

However, no Japanese person has ever won the Chopin Competition.

Shuhei and Kai competes against such rivals as: Korean twins, a Chinese person from a poor area and a Polish person, Lev Simonovsky, who is the favorite. (Section should be used like "poor section of town" or "poor section of the country." By itself it can be too vague.)

Even though you aren't Japanese, it is still really impressive since it is a tale about friendship and rivalry.

It is also hopeful. (alternate: inspirational )

On second thought （or: After some deliberation), Shuhei resolved to perticipate the following year's Chopin Competition because he wanted to beat Kai this time around.

Shuhei's psychology is depicted in particularly detail. (or: is particularly intricate )

The series started in 1998, but it was stopped halfway in 2004 since the comic magazine was discontinued.

It has restarted another series of comic magazine in 2006.

A Japanese person, Ayako Uehara, won the Piano Award for the International Tchaikovsky Competition in 2002.

He accepted the offer, though reluctant to do so, for he had never performed in public before.

Shuhei was relieved to hear Kai still playing; so he then returned to Vienna.

The comic magazine series has lasted 13 years; including two years' discontinuation and the 21st volume of the comic is going to be published this month.
