The Riasu (or Saw-tooth) Sanriku Coastline is a raised coastline of 600km in total that spreads out from southeast of the Aomori Prefecture through the coast of the Iwate Prefecture to Ojika Peninsula in Miyagi Prefecture. Sanriku (or three riku) is a generic term referring to Mutsu in Aomori, Rikuchuu in Aomori and Rikuzen in Miyagi. The Riasu coast is a jagged stretch of coastline that consists of many long, narrow coastal inlets which uniformly cut into the coastal lands creating the appearance of saw teeth.
Offshore at the Sanriku coast is where the Okhotsk current (Oyashio) , a cold current, and the Japan Current (Kuroshio), a warm current, meet, creating a rich fishing spot that is considered to be one of the Four Great Fishing Grounds in the world.
The precipitous cliffs of the Sanriku coast are also an ideal breeding ground for wild birds such as osprey, Japanese cormorant and black-tailed gull.
Along the Riasu Sanriku Coastline there are many spectacular vistas created by the raging waves and rain storms of the Pacific Ocean.
A beautiful view of autumn leaves may be seen from late October to early November in Takanose Valley near Naga in Tokushima Prefecture.
This sight became famous in 1980, when it received the most votes in a poll for the 100 (Best) Tourist Spots in Tokushima. The poll was part of the commemoration of the prefecture’s 100th anniversary.
'Kouyou-no-nishiki' (a tapestry of autumn leaves) became the specialty of this region, along with the Kitou cedar and the Kitou yuzu.
The autumn leaves cover the sharply-sloping sides of the valley, which was formed by the headstreams of the Nakagawa River. This magnificent view stuns all those who see it. The turning maple leaves are especially beautiful, making the valley the best-loved scenic spot in Shikoku.
In other seasons, too, Takanose Valley is attractive for the tender green leaves of spring, the deep green leaves of summer, and the snow-covered landscapes of winter. This makes the area appealing to tourists all year round.
Kutsuki-kei (also Kutsuki Keikoku or Omi Yabakei) is a scenic site in Kutsuki, Takashima, Shiga Prefecture.
Kutsuki-kei is a valley featuring pristine nature. The valley extends for about 3km from Takaiwa Bridge to Arakawa Bridge. The presence of irregular-shaped rocks and the silent flow of water make Kutsuki a fantastic sightseeing spot.
The v-shaped valley is formed between the Tanba and Hira mountain ranges. In spring and summer, many fishermen come to the Ado River that runs through the valley. The valley is located to the northeast of Kutsuki village and is especially beautiful at the time of the autumnal leaves.
Because the Ado River provides a passageway for fishing boats to enter the Sea of Japan from the villages, it is also called 'the Mackerel Way'. Kutsuki valley is indeed a scenic spot, which shows off nature's magnificence.
Three-Storied Waterfall (Sandan-no-Taki) is located in Rarumanai Nature Park in Eniwa, Hokkaido, and is the lowest of three waterfalls in the park.
The waterfall is fed by a mountain stream that comes down from Mt Shimamatsu. From the Rarumanai River the water drops 20m down a cliff, whose three steps give the waterfall its name. While not so big, the waterfall carries a high volume of water and appears powerful. This area was originally a valley, so the sound of the waterfall is amplified to give it a greater roar.
You can see the whole waterfall from a nearby bridge but if you want to enjoy a panorama, you should go down to the lowest dry riverbed. At the riverbed, it is true that you cannot see the first step of the falls, but the overwhelming sight is very refreshing. In autumn, the maple leaves redden and you can appreciate a spectacular and gorgeous view.
Momiji River runs down through a valley on Mt. Omoshiro, which lies to the northeast of the city of Yamagata.
A hiking course along the valley enables you to enjoy nature throughout the four seasons, and it is very popular with sightseers.
The valley is especially beautiful between late October and mid November when the leaves turn red or yellow; this change is called 'momiji' and is the origin of the name Momiji River.
The 2km hiking course takes about 40 minutes to walk along slowly. Here and there running into the valley are waterfalls such as 'Wisteria Waterfall' and 'Illusional Dragon Waterfall'. Moreover, there are many unique rocks in the valley such as 'Whale Rock' or 'Treasure Rock'. And there are many strange ones, too.
Visitors can enjoy a variety of views of the river; some parts of the river are broad and some run between rocks. The canyon is also very popular among photographers.
The view of the dense trees closing in on Fudousawa Creek deep inside Tsubakuro Valley in Fukushima Prefecture is splendid. It is also one of the most famous fall-leaf viewing spots along the Bandai-aduma skyline, as well as being one of the eight great Aduma viewing spots.
The name Tsubakuro comes from the fact that Asian spotted martins (or iwatsubame in Japanese) often used to fly through and above the valley.
A new Fudousawa Bridge, rebuilt in 2002, allows for visitors to look down on the narrow valley from 80m above. The view of the valley during autumn is breathtaking and the contrast between the variously colored leaves and the white waters of the creek is quite beautiful.
Kuragari Valley is in Okazaki, Aichi Prefecture, and has a forest. There are facilities here, such as a campground. The valley is located 26km east of Okazaki near the Hongusan Prefectural Nature Reserve.
The valley lies between 250m and 600m above sea level. Flowing through the valley is Otokogawa River. In the forest are both evergreen and broad-leaf trees, with streams of many sizes flowing among them.
People enjoy the forest as a place for recreation and relaxation. In spring, birds sing, while summer days are filled with the croaking of 'kajika' frogs. Nature continually delights visitors and refreshes them. From the highest point the Southern Alps can be seen ranging across the horizon.
The Kisagi Basin is a bizarrely shaped shoal, located in the Sasano ravine in Kamitsue-machi, Hita, Oita Prefecture. The strangely shaped rocks and the massive rocks of the Hoshihara layer, which completely change the flow of the river, created the ravines near the Kantani Bridge. This bridge spans the middle reaches of the Kawahara River.
The natural landscape of the basin, which is some 20m wide, possesses a mysterious beauty. Its colors change subtly and marvellously with each season. Besides conifers, there are various broadleaf trees, such as chestnut, dogwood, soyogo and azebi, that enclose the Kisagi Basin, giving it the wonderful appearance of a botanical garden. The ambience of the Kisagi Basin becomes more vibrant in the autumn as the red leaves on the riverbank glow elegantly in the sunlight.
The Kisagi Basin is a lovely place, giving visitors a sense of joy, tranquility and harmony with nature.
