Aso‐Kuju National Park
Wetland designated as a "Ramsar Site"
Bogatsuru Moor
What kind of place is
the Bogatsuru Moor?
Kyuden Mirai Foundationʼs efforts
to conserve the Bogatsuru Moor area
with local communities
To protect the indigenous species, including
many endangered ones, we exterminate alien
species.
We are engaged in an activity on Mt. Hiijidake,
next to the Bogatsuru Moor, to conserve the
miyama-kirishima azalea as a spring staple in the
Kuju area, by cutting down bushes that obstruct
the growth of the azaleas, as well as maintaining
the mountain trails.
We burn the fields to exterminate insect pests,
prevent bushes and miscellaneous trees from
encroaching onto the moor, and facilitate the
sprouting of plants, with the aim of maintaining
the natural environment of the wetland.

Surrounded by mountains, including Mt. Hiijidake and Mt. Mimatayama,
the Bogatsuru Moor (Taketa City, Oita Prefecture) is located nearly at the
center of the Kuju mountain range.
Since the moor is about 1,200 meters above sea level, the highest place of
ground among the moors on the island of Kyushu, it is inhabited by beautiful
wild plants, such as nohanashobu (Japanese iris) and sawagikyo (lobelia).
The Bogatsuru Moor has long been known as a billeting area for climbers
in the Kuju mountains, some of whom stay in the Hokkein Onsen hot spring
area on the moor or sleep in their tents, which sometimes form a colorful
carpet on the moor. This place is one of Kyushu’s most popular destinations
for climbers.
In 2005, the Bogatsuru Moor, together with the Tadewara Moor, was
collectively designated as a "Ramsar Site," that is, a wetland of international
importance, under the name of Kuju Bogatsuru and Tadewara-shitsugen.
The Ramsar Convention is a convention on wetlands signed at an
international conference in the city of Ramsar, Iran, on February 2, 1971. Its
official name is the Convention on Wetlands of International Importance
especially as Waterfowl Habitat, but it is commonly called the Ramsar
Convention after the city where it was signed.
