The Kozomi Kaigan Coast is a beautiful beach between capes, turning into a crowded beach resort insummer. To its west, the Ushigome Kaigan Coast is also a popular coast, like a private beach. Behindthese beaches are small sand dunes, whose southern part is wetlands used for paddy fields.

Don’t miss the geomorphological features of sand dunes,
a work of nature!
This area features mountain ridges extending in cape-like shape into the Japan Sea,and small sand dunes behind bays between capes. The waves in the Japan Sea andstrong northwesterly winds caused sand dunes to develop, turning enclosed bays
and ponds into wetlands. Walk around the Kozomi area to experience the geologicalfeatures of the sand dunes and local people’s lifestyles.

What are the black sand grains?

A dike as magma’s pathMagma erupts through underground joints onto the ground surface. Dikes are magmathat was cooled into rock in the underground joints before reaching the ground surface
and erupting. A close look at the dike on the Ushigome Kaigan Coast shows joints
running at right angles to the dike edge (indicated with the dashed lines drawn on thephoto).
These joints formed because magma contracted while being cooled into rock.
Seen from a three-dimensional perspective, the dikecomprises pentagonal and hexagonal column-likefractures called “columnar joints,” as shown in thefigure below. This dike traverses the cape from east
to west, and also outcrops at the western end of theDike proﬁleLava
Kozomi Kaigan Coast. Moreover, just above the dikeat the cape ridge is Kitano Shrine.

Located in the south of the Mizushiri Kaigan Coast tothe west of the Kozomi Kaigan Coast, the Mizushiri
Pond formed as a lagoon that resulted from anenclosed bay’s separation from the sea due to thedevelopment of the sand dunes in the Mizushiri Kaigan
Coast. After being reclaimed to make paddy fields in
the Taisho era, the pond is currently in its original state
as a pond. The pond provides various migratory birds,
such as wild ducks, with a wintering place.

In the middle of the Kozomi Kaigan Coast is theestuary of a small stream, which has large sedimentation of black sand grains at the bottom.
This black sand is iron sand. A dig of sand on theKozomi Kaigan Coast reveals alternative layersof black iron sand and white sand. Iron sand is aferruginous mineral called “magnetite” that has
been separated from rocks in which it is originallycontained, due to weathering.
The sands in the rivers or on the coasts in theSan’in Kaigan Geopark area contain a large amount of iron sand, so they were used
as a raw material for iron-making with foot-operated bellows. In wartime, iron sand wasmined on the Kozomi Kaigan Coast too.

The cape in the west of the Kozomi Kaigan Coast isformed with andesitic lava dating back about 18 million
years. Views of the cape from the east and west showthat a 20-meter-wide andesitic dike traverses the capefrom east to west. (See Geo-Column ②.)

Mizushiri Pond

Geo-Column①

The layers found here contain large, round stones(gravel). Such layers, called “gravel layers,” arethought to have been formed by volcanic eruptions thatwere carried in a water flow and accumulated in an
alluvial fan on the skirts of the volcano.

This shrine is located on a cape in the west of theKozomi Kaigan Coast. Dedicated to Sugawara noMichizane, deified as the god of learning, the shrine
was called “Tenjin” or “Tenmangu” in olden times, andwas renamed “Kitano Shrine” in the early Meiji era. The
deity is the guardian of the Kozomi area. At the annual
festival in April, local people used to parade carrying
a festival float and sakaki branches while visiting all
houses in the area.

Ketanosaki Observatory Plaza (Hakuto no Oka)

Wetlands spreading to the south of the Kozomi hamlet
are currently used for paddy fields. In winter, after
rice is reaped, the gates on the tide-stopping weiracross the Kozomi River are closed, so the wetlands
are covered under water, and look like a pond, wherewaterfowls, such as wild ducks and herons, comeflying. (See Geo-Column ③.)

Andesitic dike

The reef off the cape tip at the western end of theKozomi Kaigan Coast is called “Akajima.” On theAkajima Reef, you can find a rugged layer containing
different-sized angular rocks covered with andesitic
lava, which formed about 18 million years ago, when
the Japan Sea expanded. Although the lava wasoriginally dark colored, it partly looks red due tooxidization. Capes located between west of the Hakuto
Kaigan Coast and east of the Mizushiri Kaigan Coast
are formed with the same lava as this.

The sand grains of the Kozomi Kaigan Coast are
uniform in size and look brilliant because of a highcontent of transparent quartz grains washed frequently
by the waves. Walking on the beach when it is dry, you
can hear the sand make high, clear squeaking sounds.
In the middle of the shoreline is the estuary of thegentle and small Kozomi River, where you can findripple patterns containing iron sand.
(See Geo-Column ①.)

A profile of the sand dunes

The Ushigome Kaigan Coast provides you with aview of a profile of the Kozomi sand dunes. A close
look at the layers of minute sand grains shows thatthe upper sloped layer, which is almost parallel to thesloped surface of the sand dunes, cuts into the lower
horizontal layer. This suggests that the winds eroded
the former sand dunes, where sand grains flew inand accumulated to form the current sand dunes.
Here, you can learn that the sand dunes thus havedeveloped through the repeated cycle of erosion andaccumulation.

Kozomi Kaiganʼs many places of interest

Dike of the Ushigome Kaigan Coast

Farming in the back slough
The lowlands to the south of the Kozomi hamlet
formed from a dried-up lagoon, which had resulted
from an enclosed bay’s separation from thesea due to the development of the sand dunes.
Because the sand dunes held back the waterflow from the mountains, the lowlands were wet
and unsuitable for farming. Therefore, in the earlyShowa era, the wetlands were improved by fillingthem in with sand from the Kozomi sand dunes sothat local people would be able to use the lowlands
for farming. Since these farmlands are located at
a very low altitude, local farmers face the risk of
having their farmlands flooded with the sea waterthat flows backward along the Kozomi River during
a storm surge or high tide. To reduce the risk, atide-stopping weir has been built at the estuary ofthe Kozomi River. In winter, after rice is reaped andwhen the Japan Sea is rough, the gates on the weir
are always closed, stopping the water from flowing
out and making the farmlands look like a pond.
