Kannon pilgrimage route. The Noh play Chikubu-
shima is set on the island. Chikubushima is associated
with such important late 16th-century warriors as
Oda Nobunaga and Toyotomi Hideyoshi.
DEJIMA
An artificial island in Nagasaki harbor that was built
in 1636 for foreign residents to keep them separated
from the population at large. The Tokugawa shogu-
nate used Dejima as a way to check the spread of
Christian missionary activity in Japan, particularly
by the Portuguese. Dejima first housed Portuguese
traders, but they were expelled from Japan in 1637.
At that time, the Dutch factory at Hirado Island (see
below) was moved to Dejima and the Dutch occu-
pied the island until the closing years of the Edo
period. Dejima was also important as a source of
Western scientific and other knowledge during the
early modern period.
HIRADO ISLAND (HIRADOSHIMA)
Hiradoshima (area: 64 square miles) is an island off
the northwest coast of Kyushu. In 1550, the island’s
port at the city of Hirado became the first port
opened to foreign trade. Dutch and Portuguese
merchants lived on the island until they were forced
to move to Dejima in 1636. The island is also con-
nected with the Hirado warrior family whose castle
was located on the island.
HOKKAIDO
Hokkaido (area: 30,107 square miles) is the second
largest and the farthest north of Japan’s four main
islands. The Tsugaru Strait separates Hokkaido
from Honshu. To Hokkaido’s west lies the Sea of
Japan, to its northeast lies the Sea of Okhotsk, and to
its south and east lies the Pacific Ocean. During the
medieval and early modern periods, Hokkaido, then
known as Ezo, was not formally a part of Japan. It
was inhabited mostly by the Ainu, a people whose
origins are not entirely clear. The name Ezo was
changed to Hokkaido in 1869. During the early Edo
period, the Matsumae domain established control
over a small part of southwestern Hokkaido and
gradually increased its holdings over much of
Hokkaido through the 19th century.
HONSHU
Honshu (area: 87,992 square miles) is Japan’s largest
island and is generally viewed as Japan’s mainland
because it comprises roughly 60 percent of Japan’s
total land area. Honshu is bordered by the Pacific
Ocean to its east and by the Sea of Japan to its west.
Most of the key events that took place in Japan’s
medieval and early modern periods occurred on Hon-
shu. The major medieval and early modern cities of
Kyoto, Kamakura, Edo, and Osaka are all on Honshu.
Not surprisingly, the majority of Japan’s population,
both historically and today, resides on this island.
Japan’s largest and most famous mountain and lake—
Mount Fuji and Lake Biwa—are both on Honshu.
ITSUKUSHIMA
Itsukushima (or, Miyajima; area: 12 square miles) is
in Hiroshima Bay in the Seto Inland Sea. The island
was considered sacred throughout the medieval and
early modern periods. As a result, giving birth or
conducting funeral rituals—both considered ritually
polluting in Shinto—were prohibited during this
time period. Itsukushima Shrine, established in the
sixth century, is famous for its vermilion torii
(Shinto gate marking the entrance to a shrine’s
precincts) which appears to float in the water at high
tide. The shrine is also associated with the Heike
warrior family.
KYUSHU
Kyushu (area: 14,177 square miles) is the third
largest and the farthest south of Japan’s four main
islands. Kyushu is bordered by the East China Sea to
its west and by the Pacific Ocean to its east. The
Shimonoseki Strait separates Kyushu from Honshu
and the Tsushima Strait separates Kyushu from
Korea to the northwest. One theory places the loca-
tion of the early Japanese state mentioned in a late
third-century Chinese history as northern Kyushu.
Whether this is true or not, Kyushu, due to its prox-
imity to the Asian mainland, was often the point of
first contact by envoys and traders going between
Japan and the mainland. The 13th-century Mongo-
lian invaders attacked Kyushu, and much of the
Japanese contact with Europeans in the 15th and
early 16th centuries occurred on this island. When
