Saikaya Yokosuka Shopping Plaza is a long-established department store with a 150-year history, which is the only Hyakkaten (department store) in Miura Peninsula now and in the past.

Founded in 1872 as a kimono shop, like other department stores in Japan.
Burned down once in 1923 due to the Great Kanto Earthquake, and reopened as a department store in 1928.
It was closed again in February 2021 in the wake of the recession but reopened the following month in response to the local people's voices.
For the day of reopening, more than 100 people lined up for the opening.

Rooted to the locals, and meet the local needs.
Groceries, slow-fashion clothes and accessories, restaurants, and seasonal gifts are all in one place.

The newly built south wing has amusement facilities such as karaoke, darts, and rentals of e-sports or office space.

Everything you need is available, with the best customer service.
