Yokosuka (Japanese: 横須賀市; -shi) is a city located in Kanagawa, Japan.
It is located at the mouth of Tokyo Bay in the Miura Peninsula, and the city stretches across the peninsula to Sagami Bay. Its neighbors are Yokohama, Miura, Hayama, and Zushi.

Lets start with a little history of Yokosuka:

The adventurer William Adams (inspiration for a character in the novel Shogun), the first Briton to set foot in Japan, arrived at Uraga aboard the "Liefde" in 1600. In 1612, he was granted the title of samurai and a fief in Hemi within the boundaries of present-day Yokosuka, due to his services to the Shogun. There he founded a family with Oyuki, the daughter of Magome Kageyu, a noble samurai and official of Edo Castle. William and Oyuki had a son called Joseph, and a daughter, Susanna. A monument to William Adams, called Miura Anjin in Japanese, is still visible in Yokosuka.
The Tokugawa shogunate established the post of Uraga Bugyō in 1720. To defend Edo Bay, they established an outpost at Ōtsu in 1842.
In 1853, United States naval officer Matthew Perry arrived in Tokyo Bay with his fleet of Black Ships and came ashore near present day Yokosuka, leading to the opening of diplomatic and trade relations between Japan and the United States.
The Yokosuka Iron Foundry was established on the site in the city in 1865, and the French engineer Léonce Verny spent the next ten years supervising the development of shipbuilding facilities.
Yokosuka became the first modern arsenal to be created in Japan. The construction of the arsenal was the central point of a global modern infrastructure, that was to prove an important first step for the modernization of Japan's industry. Modern buildings, the Hashirimizu waterway, foundries, brick factories, technical schools to train Japanese technicians were established.

This street, near the main gate of the U.S. Naval Base in Yokosuka, is symbolic of the military presence here in the City.

The area is imbued with an international flavor and buzzes with activity as young people flock to the Dobuita bazaars, which are held several times a year, and other events. It is also known as the birthplace of the popular "sukajan" jacket.

Perry Park
This park was built to commemorate the arrival of Commodore Perry in Japan in 1853, which served as the impetus for the subsequent opening of Japan. There is a monument in the park with an inscription written by Hirobumi Ito, a former prime minister, and a memorial hall with exhibits of materials relating to Commodore Perry and his coming to Japan, giving us today a taste of the historical events of the time.

Tsukayama Prefectural Park
This park was developed around the so-called Anjinzuka (monument in memory of Anjin Miura and his wife), a nationally-designed historical site.
Anjin Miura (an Englishman by the name of William Adams) acted as a diplomatic adviser to Ieyasu Tokugawa, the 1st Shogun of the Edo period, during the early 17th century and, in return, was granted the village of Hemi as his own personal fief. He also provided knowledge about artillery, shipbuilding, navigation and other aspects of Western culture. There are about 1,000 cherry trees in the park and a cherry blossom festival is held every spring, which attracts large numbers of visitors to view the cherry blossoms.

How to access there:

Tateishi (Monolith)
The natural stone monolith on Akiya beach, which soars to a height of 12 meters and is 30 meters in circumference, is depicted in the woodblock print entitled Soshu Miura Akiya-no-Sato (literally, the Village of Akiya in Miura in the Province of Sagami) by woodblock print artist Hiroshige Ando, Sr. The beauty of this scenic spot has been known since long in the past and, particularly at dusk, the way it seems to linger there against the silhouette of Mt. Fuji is reminiscent of a scroll painting.

How to access there:
From JR Zushi Station, take the bus bound for Nagai and get off at the Tateishi bus stop. It is a one minute walk from there.

Mikasa Park
This park, designed around the theme of "water, light and sound" so typical of Yokosuka, has also been selected for inclusion in the 100 Urban Parks of Japan. With water fountains that dance in time with the music, monuments that shine brightly with reflected light and murmuring brooks flowing throughout, it is a charming oasis in the middle of the business district. The battleship Mikasa, which was active as the flagship in the Battle of the Japan Sea (1905) during the Russo-Japanese War, is preserved in the park as a memorial, giving us a chance now to relive the intensity of that sea battle.

Kurihama Hana-no-Kuni (Kurihama Flower World)
The poppies in the spring and cosmos in the fall have become well-known and imbue Yokosuka with a lyric touch. There are many facilities available, including the Herb Garden and Adventure Land, where you can always find something to enjoy during any season of the year.

Herb Garden
This is the largest herb garden in the greater Tokyo metropolitan area. The expansive site features some 108,000 plants of 240 varieties and both the flowers and fragrance charm visitors who come throughout the year. There is a restaurant and shop in the Herb Garden. At the restaurant, you can enjoy Mediterranean or genuine French cuisine containing the herbs while gazing out over the sea. In addition, you can also purchase herb plants and related goods at the shop.

Adventure Land
Large wooden playground equipment has been set up on the broad site. The little ones can have fun all day long with their parents at this playground and develop their physical strength at the same time.

Poppy and Cosmos Gardens
Many visitors come not only from the city but from more distant points to see the stunning displays of a million poppies in the spring and cosmos in the fall all blooming at once. The restaurant at the entrance specializes in Japanese-style food.

Flower Train
A three-car bus winds its way like a train along the roads in the park for about two kilometers from the Kurihama Hana-no-kuni entrance gate to the parking lot by the Herb Garden. Along the way, the bus makes a brief stop at Adventure Land and at the Herb Garden.

Park Golf Course
Park golf is sort of a cross between golf and gate ball with rules and equipment that are much like those of golf. You can rent equipment there (a fee will be charged) and it is easy for everyone from young to old to have fun playing.
