Your web site says that "Takeshima is
indisputably an inherent part of the territory of Japan, in light of historical
facts."
It is definitely wrong.
Until Chosun dynasty, Dokdo was under
control by Korean people.
During Japanese colonial era, Japan had
diplomatic rights of Korean territory, and
Japan distorted Korean territory.
After the Second World War end, Japan
should correct what they distorted about Korean territory including Dokdo.
Still, historical misleading remains until
now.
