Tottori Sand Dunes

Tottori Sand Dunes
Measuring 16 km east-west and 2.4 km north-south the Tottori Sand Dunes are Japan's largest sand dunes.
The dunes were formed by sand flowing down from the Chugoku Mountains, carried by rivers and ocean winds, which then shaped the sand into dunes. Here beautiful patterns created by the sand and wind (wind ripples) and bowl-shaped depressions can be seen, and this unique, richly varying and undulating topography is one of the attractions of the Tottori Sand Dunes.
Sengan-Matsushima Island

Sengan-Matsushima Island
This small granite island can be found floating in the ocean immediately north of Ajiro Port. During the Kanbun Era (approx. 300 years ago), there was a magnificent pine tree growing at the top of the rock, and legend has it that Ikeda Tsunakiyo, the Second Lord of the Tottori Domain, decreed that "Whosoever moves this pine with the rock attached to my garden shall receive 1,000 kan ("sen-gan") of silver", and this is how the island is said to have gotten its name.

Ryujin-do Cave
These caves were created through wave erosion along faults in the rock. The caves are divided into two--East Cave (Kairyujin) and West Cave (Okaryujin); house martins build nests in the walls, and greater horseshoe bats live inside the caves.
Anami Beach

Anami Beach
Created through the erosion of andesite formed at the time the Japan Sea was formed, this rocky shore is dotted with tiny islands, including meotoiwa ("husband-wife rock") pairs. Rhyolite dikes with numerous bale-shaped columnar joints form promontories and islets.
Ryugu Sea Cave

Ryugu Sea Cave
The cave gained its name because the andesite dike below appears to be climbing the granite walls to the sky like a dragon (ryu), while a cave (domon) was also carved out of the andesite.
Mio-Oshima Island

A cove where a reef called Senjojiki ("flat like 1,000 tatami mats") lies side-by-side with a white sandy beach, Imagoura is an excellent place to enjoy swimming or camping. It is also called Kaeru-jima Island ("Frog Island" because of its shape, and various unique landforms can also be seen here, such as Shiraishijima Island, which has an unusual shape reminiscent of the sole of someone's foot or jewels.
Hasakari-iwa Rocks

Hasakari-iwa Rocks
Located on the shoreline of the Takeno Beach in an area of wave-cut cliffs, this landform is a rock gate formed along conglomerate strata. The rock forming the roof of a sea cave is thought to have fallen and stuck between the cave walls. The site is designated by Hyogo Prefecture as a Place of Scenic Beauty.
Takeno Beach

Takeno Beach
A shoaling beach approx. 800 m in length, Takeno Beach has been selected as one of Japan's Top 100 Bathing Beaches due to the high transparency of the water here. It has also ranked in Japan's Top 100 Waves, Japan's Top 55 Bathing Beaches, and Japan's Top 88 Bathing Beaches, making it one of Japan's representative bathing beaches.
Shotenkyo

Shotenkyo
A beautiful dune area dividing Kumi-hama Bay from the Sea of Japan, Shotenkyo has been selected as one of Kyoto's Top 200 nature sites. The area came to be called Shotenkyo ("Little Bridge to Heaven") because of its similar shape to the Amanohashi-date ("Bridge to Heaven") sandbar.
Tango Sand Dunes

Wave-cut benches can be seen along this rocky shoreline. In tidal pools and potholes in the benches, it is possible to observe ocean creatures. The beach got the name Goshiki ("Five Colors") Beach because of the various different colors of the pebbles there.
