It is unknown when and from where rice cultivation came down to Japan.
Some people say rice cultivation came from China, some people say from Okinawa, and others say from Korean Peninsula.
But Korean people claim that they taught Japanese people rice cultivation without hard evidence.

Korean people always want to become a "colonial master" of Japanese culture by claiming that
Japanese culture originated from Korea.
But it is no use claiming it.
Because there is a historic fact with more
unimpeachable evidence than "origin" delusion of Korean people.
The fact is that Korean people are now eating Japanese rice, not Korean native rice.
This rice was improved through artificial breeding by Japanese under Japanese rule.
Before Japanese rule, Korean people were eating Korean native rice, which
is contaminated by many red rice(ancient rice) and tiny stones.
Japanese people regard this as an anathema, saying this was not food for
people.
Red rice(ancient race)
Under Japanese rule, Japanese landlords immigrated to Korean Peninsula, and
began to cultivate Japanese rice with Japanese agricultural technology.
As Japanese rice production increased in Korean Peninsula, it became to
have a better reputation,.and its export to Japan increased. Then, in
Korean Peninsula, the production of Japanese rice increased furthermore,
As a result, Korean native rice
dumped into the dustbin.
The first recommended Japanese rice variety in Korean Peninsula was called
kameno-o
which was the ancestry of the most famous brand rice in Japan now..
This rice variety is named "Koshihikru".
This "kameno-o" was a cold-resistant variety which was developed by Abe
Kameji in 1893.
(Sake made from Kameno-o)
This Sake is famous also as as a model for Manga named "Sake of Natsuko".
After that, "crossbreeding ", the new technique of breed improvement
developed in Japan.
Crossbreeding kameno-o
with other variety produced "rikuu132gou" in 1921.
Miyazawa Kenji worked to promote this variety.
He was the famous poet.

Thus this delicious and disease-resistant
rikuu132gou was spread all over the Korean Peninsula.

Japanese rice became widespread.in Korean Peninsula. In addition, Japanese
agricultural technology was imported. For example, irrigation technology,
fertilizer and cultivation method(regular planting).
Then Korean people was cultivating Japanese rice by Japanese agricultural
technology immediately after their independece.
After Korea was separated from Japan, Japan has developed a variety of rice
more than (one was) before.
In 1949, Japan developed "koshihikari" which
was 4th generation descendant of "kameno-o".
("koshihikari" is now most popular brand in Japan)

"Koshihikari" is so delicious that it is also popular in Korea.
"Koshihikari" is allowed to cultive only in Gyeonggi-do.
In January 2006, the 85% of "koshihikari from Japan" was exposed as fake in Korea.

The rice Korean people eat now is not Korean native rice but Japanese rice
which Japanese brought to Korean Peninsula, and cultivated by the agricultural
technology of Japan.
In many parts of today's Korean people's lives, it is impossible to deny
or ignore influence from what Korean people learned from Japanese under
Japanese rule.
