Uraga — New port & marina
Construction of the nation’s first superyacht marina is set to begin as early as 2027 in Yokosuka, Kanagawa Prefecture.
The redevelopment project centers on the former site of Sumitomo Heavy Industries Ltd.’s Uraga shipyard, an iconic site that once symbolized Japan’s status as a global shipbuilding powerhouse. The project is slated to be completed in stages from 2029.
The Yokosuka city government and Sumitomo Heavy Industries, the landowners, signed a partnership agreement on March 30 with and Index Inc. regarding the Uraga Station area revitalization project, a massive undertaking with total costs exceeding ¥100 billion.
Index, based in Minato Ward, Tokyo, represents the preferred negotiator Team Perry’s in the deal involving the city and Sumitomo Heavy Industries.
At a signing ceremony held at the Yokosuka city hall, Mayor Katsuaki Kamiji, Sumitomo Heavy Industries President Toshiro Watanabe and Index President Koichi Uemura were in attendance.
“This plan embodies what I consider to be the ‘second opening of the country,’” Kamiji said in his address.
The master plan presented at the ceremony targets wealthy individuals from Japan and abroad, featuring a superyacht marina capable of mooring 60-meter-long luxury vessels. The project also features twin hotels that will serve as a symbolic gateway to the area, alongside residential condominium towers.
The site is envisioned as a hub for marine-related matters, hosting international meetings and providing opportunities for historical and cultural learning.
Architect Kengo Kuma, who formulated the plan, stressed that the project is environmentally friendly. “Multiple streets arranged within the district will connect the sea and the land, playing a role in linking the history of Uraga,” Kuma added.

UWAMACHI -- Yokosuka's "Upper Town"
Ancient Burial Mound Park
== Ōtsukadai Kofun Park
The Otsuka Kofun is the largest keyhole-shaped burial mound on the Miura Peninsula, and it was actually located about 80 meters northeast of this park, at the summit with an elevation of around 77 meters. However, it disappeared due to a land readjustment project.
The Otsuka Kofun group was discovered in 1924 (Taisho 13) by Dr. Naotada Akaboshi.
Excavations were conducted in 1952 (Showa 27) and from 1992 (Heisei 4) to 1994 (Heisei 6), confirming three keyhole-shaped burial mounds and three round burial mounds.
Within Otsukadai Kofun Park, Tumulus No. 1 is a restored kofun and is called the Otsuka Kofun.
It is a keyhole-shaped tumulus that was located at the top of the Otsukadai hill. From the top of the rear circular portion, at an elevation of about 78 meters, one could see far away to Mount Fuji and even as far as Tokyo Bay.
From the posterior circular part, a shallow pit-shaped coffin bed facing the east-west direction has been confirmed, measuring 3.05 meters along the major axis, 1.17 meters along the minor axis, and 35 centimeters in depth. The coffin bed is the place where the coffin was placed, but the coffin itself has not survived, possibly because it was made of wood.
Around the coffin bed, two straight swords, one small knife, more than fifteen iron arrowheads, two earrings, and more than forty small glass beads were excavated. Additionally, one piece of cracked Sue ware (unglazed pottery) was found in the earthen cover above the coffin bed.

There were eight archaeological sites from various periods in the Yoshii-Ikeda area.
-- At the Otsukadai site, remains of early Jomon period dwellings and anti-aircraft gun positions from World War II were excavated.
-- At the Aoike site, fragments of pottery from the middle Jomon period were excavated.
-- At the Mitsuaridani site, remains of dwellings from the late Yayoi period to the early Kofun period, as well as burial mounds called hōkei shūkōbo (rectangular moat tombs), were excavated.
-- At the Omochi site, Kami-Yoshii North site, and Kami-Yoshii South site, remains of dwellings from the late Kofun period through the Nara and Heian periods were excavated.
-- At the Nishitani site, stone-lined underground channels from around the Sengoku period were excavated.

There is a large jar used for storing food. The fact that such a large jar can be made suggests the advancement of pottery-making techniques and the abundance of food.
This large jar is called "Sue ware", a type of new pottery introduced from Korea. Since it is fired at high temperatures in a full-scale kiln, it is hard and durable.

Iron arrowheads (arrow tips made of iron) were attached to the tip of an arrow to enhance its lethality.
In the early Jomon period, stone arrowheads made of stone or bone arrowheads made of bone were mainstream. In the Yayoi period, they began to be made of bronze, and in the Kofun period, they came to be made of iron.
Since iron was not something that everyone could obtain, as time went on, the gap between the rich and poor, and between rulers and the ruled, widened.

Special Ship Retires in Yokosuka
The journey of "Mirai" was itself a testament to the culmination of Japanese science and technology. Its predecessor was Japan's first nuclear-powered ship, "Mutsu." In 1997, it was reborn as a state-of-the-art research vessel powered primarily by a diesel engine, enabling observations in previously challenging conditions, such as extremely cold seas and rough weather. With a length of 128.5 meters and a weight of 8,706 tons, its size was also a weapon for ensuring stable data collection even in turbulent waves.
Over 28 years, it traveled approximately 2.3 million kilometers (equivalent to 58 trips around the Earth). It made over 20 Arctic voyages, alerting the world to the severe reality of declining sea ice. In research that forecasts humanity's future—such as studies on climate change phenomena and global warming—it was recognized by scientists worldwide as a "floating ocean laboratory."
Currently, construction is underway on "Mirai II," which is scheduled to take over the duties of Mirai, with completion aimed for around November this year.

Yokosuka's "Mascot Character"
Japan is famous around the world for its "soft power" and producing lots of comics (manga -- 漫画) and cartoons (anime -- アニメ). In keeping with its imaginative & visual artistic culture, some Japanese agencies, groups, or businesses produce what are called "mascot characters" (マスコットキャラクター) as cute and approachable representatives of their organizations. Like the masked & costumed actors at Disneyland, a mascot character is a cute, quirky figure created to represent a place, event, organization, or company -- usually to promote local pride, tourism, or branding. They are designed with simple, endearing features and often embody regional culture, history, or products. The mascots embody the spirit of their region, acting as approachable ambassadors that connect people emotionally to a place or brand. Of note, Yokosuka City Government has its own mascot character called: "SUKARIN" (スカリン -- see image below). SUKARIN was created back in 2007 to commemorate the 100th anniversary of the city. The design was chosen through a public contest. It is said to be a fairy that came from the sea and its gender is unknown. The name comes from a combination of Yokosuka (SUKA) and marine/sea (RIN). SUKARIN's blue color is inspired by the sea of Yokosuka harbor -- and it wears a small sailboat as a hat. SUKARIN is used and displayed in support of many activities, publications, and events in Yokosuka.
