Spice Works Holdings Co., Ltd. (Headquarters: Taito-ku, Tokyo) will open "Ajiman," a restaurant specializing in seafood bowls featuring local fish, in the Iwai Beach area of Minamiboso City, Chiba Prefecture.
This establishment is not just a restaurant but a community exchange hub designed to promote the charms of Minamiboso's nature, food culture, and people, with a view to introducing regional specialties and revitalizing local ingredients. We aim to build a community-rooted restaurant together with everyone for decades to come.
■ A Place to "Come for a Weekend Deep Breath," Not Just a Tourist Spot
In recent years, with changes in work styles and lifestyles, "micro-retreats" – spending time to reset oneself away from the hustle and bustle, rather than long-distance travel – have been gaining attention. We view Minamiboso not as a "tourist destination" but as a place with such value.
Minamiboso, about 80 minutes from the city center, lacks the flashiness of famous tourist spots, but it offers calm seas, a slowly flowing time, and abundant food.
It retains many charms that are not yet widely known. Ajiman starts as a place to convey these charms through "food."
■ Revitalizing a Traditional House, with a Treehouse in the Garden
The restaurant utilizes a traditional house that remained in the area.
Furthermore, a treehouse has been installed in the garden, creating a space where adults, children, and even dogs can enjoy themselves.
We aim to be a lodging-style restaurant where guests can spend their time leisurely while feeling the sea breeze, not just for meals.
Experience the nostalgia of the Showa era and the extraordinary feeling of spending time in nature.
You can experience time that is uniquely Minamiboso.
■ "Today's Fish" Changes Daily
The sea of Minamiboso is a warm sea area influenced by the Kuroshio Current.
It is known as one of Japan's leading fishing grounds, where a wide variety of fish and shellfish are landed due to the confluence of the strong currents of the outer Boso coast and the calm seas of the inner Boso coast.
At Ajiman, we cherish the culture of "eating fish caught in the morning on the same day" that has existed around Iwai Beach for a long time. We offer fish centered on freshly caught local fish, sourced from a market just a 50-second drive from the restaurant every morning, ensuring unparalleled freshness. You can savor the freshness and the local atmosphere.
The menu changes daily depending on the season and fishing conditions, offering the pleasure of encountering different tastes with each visit.
We aim to be a restaurant where memories of visiting Minamiboso remain in your heart along with a bowl of our food.
Our company has operated restaurants across Japan, and starting with this establishment, we will also focus on initiatives to promote the charms of various regions in the future.
Through Ajiman, we aim to increase fans of Minamiboso and foster "related population" engagement not only with tourists but also with local residents on an ongoing basis.
