represents

For example，倭.

When I look at pronunciation of this Chinese character in the Chinese characters dictionary.
(Of course, for Japanese.)

①イ(i)
②カ(ka)，クヮ(kuwa')
③ワ(wa)

It is described so.
Pronunciation of a Chinese character.
I do not say categorically，but it is so diverse in Japan.

By the way，all of these were the pronunciation of China originally.
　
"Yamato."
This pronunciation of the Japanese style is not described in this Chinese characters dictionary.
　
Today，general pronunciation of 倭 in Japan is "wa".
"Yamato" is rarely used as pronunciation indicating the 倭.
If anything，this is in the category of phonetic equivalent at present.

② is "漢".
③ is "呉".
　
Well，Chinese characters of these.
It is appended to this description.
　
"The time that the pronunciation of this Chinese characters have been introduced to Japan."
This shows it.　
　
In short，漢 is the pronunciation of 漢.
呉 is the pronunciation of 呉.　
　

・・・・・・・・・
　
　
"漢(the Han dynasty)" is a long-term unified dynasty of China first.
(208BC‐8AD，25AD‐220AD)
　
After the fall of its 漢，until unification of 隋(the Sui dynasty) of 589AD.
About 370 years，China was the era of division.
　
And its initial, it was the era of the Three Kingdoms.　(220AD-280AD)
"呉(the Wu dynasty)" was its southern dynasty.　(222AD-280AD)　
　　
However，in this case，its meaning is different.　

This 漢 does not represent the Han dynasty.
In this case，it represents the China of after Sui Dynasty unified.

And 呉.
It does not represent the Wu dynasty only.
It represents the southern dynasty of era of division.
　
In short，time of 呉 is earlier than 漢.

Note：漢 represent the China.
This feeling is strong in Japan even now


・・・・・・・・・
　
　
Kings of Japan.
According to the history book at the time of China，
they seems to were often sent envoys to this southern dynasty.

"Five kings of Japan has been sent envoys."
Such record remains.
　
However，record of Japanese side is not clear yet about it.

Envoy of the last king of the five kings.
According to this record，it was 478AD.
　
Record in Japan become clear.
It seems from this time roughly.
