【Press Release】 “Tsumugi Suite Villa”, a new guest room where you can enjoy the nature and culture of Amami, is now available! ~Oshima Tsumugi x Art x Upcycling

(Head office: Amami Innovation Corporation, Amami City, Kagoshima Prefecture / President: Yasuhiro Yamashita), which is engaged in community development through the operation of accommodation facilities in the Amami Islands, is pleased to announce the launch of the 20th new guest room “Tsumugi Suite Villa” at “The Beachfront MIJORA” in Denpaku. Tsumugi Suite Villa”, the 20th guest room in “Denpaku The Beachfront MIJORA”, is now on sale.

The Beachfront MIJORA is a retreat villa that offers a lodging experience to help guests forget the hustle and bustle of daily life and prepare their minds through the great nature of Amami, based on the concept of “communicating with the nature of the island. The “Tsumugi” in the newly created “Tsumugi Suite Villa” represents Oshima silk, a traditional craft that has been handed down for approximately 1,300 years on Amami Oshima. This time, together with Mr. Masaken Moto, an Oshima Tsumugi weaver who has been in business for 8 generations in Amami Oshima, and Mr. Shingo Minami, an Oshima Tsumugi weaver who has been in business for over 60 years, we have re-edited and tailored the charm of Oshima Tsumugi into the guest rooms, creating a unique and original space that is embraced by the Amami nature.
This activity is one of Den Tomari’s efforts to pass on traditional Amami crafts such as Oshima tsumugi to the next generation.
The beautiful sea seen through the wide windows over 10 meters wide and the cultural and creative art space woven with Oshima tsumugi silk will provide you with a relaxing moment.

 

What is “Denpaku The Beachfront MIJORA”?


Denpaku The Beachfront MIJORA, a luxury villa retreat, was established in July 2019 and is the fourth accommodation facility developed by Denpaku. The concept of Denpaku The Beachfront MIJORA is “to interact with the nature of the island”. The view reflected in the largest glass window available in Amami is like a picture of the ever-changing sea and sky spread out before your eyes. The building also features a roof made of burnt cedar, inspired by Amami’s traditional “Takakura” architecture. It offers a tranquil and zen-like lodging experience where one forgets the hustle and bustle of daily life and faces the nature in front of one’s eyes.

 

What is the new “Tsumugi Suite Villa” where you can enjoy a stay of a higher rank?


The new “Tsumugi Suite Villa” is the largest villa in Denpaku The Beachfront MIJORA, with 86 square meters, and can accommodate up to 4 guests.The theme of the villa is “Oshima Tsumugi x Art x Upcycling,” and upcycled materials from Oshima Tsumugi, a traditional Amami-Oshima craft with a history of 1,300 years and called one of the world’s three major textiles, are scattered throughout the villa. It is a creative art space that is typical of Denpaku, which weaves tradition into the future.

The Tsumugi Suite Villa is located on the second floor across the street from the other buildings, and its over 10-meter-wide glass windows overlook the seven-colored sea. The organic roof, which is reminiscent of the Amami sea and bobbing like waves, has more presence when illuminated by the Ryukyu glass, creating a fantastic experience as if you are looking at the surface of the water from inside the sea. The room offers a culturally healing experience while swaying in the egg chair installed in the room with a book selected from the mini library of books related to Amami in one hand.

Feature 1: One-of-a-kind Japanese-style room dressed in upcycled Oshima tsumugi “Amami cloth

The wallpaper is made of custom-directed “Amami Cloth” woven with 9 pieces of white Oshima silk threads torn into 5 mm lengths for the warp, and white silver threads and mud-dyed gold threads for the weft.
The wallpaper is based on the color white, but changes with the light, making it a special space where you can enjoy the passage of time.

What is “Amami cloth” upcycled from Oshima tsumugi?

Oshima tsumugi”, a traditional craft of Amami-Oshima Island, has lost its chance to be worn as well as the kimono has become less popular all over Japan. Amamifu” was developed by Mr. Masakazu Moto with the hope that people will continue to love it even in this new era. It utilizes a technique called saki-weaving, in which old Oshima tsumugi cloth is ripped and a new cloth is woven from the weft. This innovative weaving technique uses traditional tools, which allows Amami craftsmen to work and helps to pass on traditional techniques.

Feature 2: Bathroom to relax while savoring “White Oshima Tsumugi” all at once.

This bathroom is the only one of its kind in the world, with the entire wall covered with tiles made of Oshima tsumugi fabric and specially coated glass. The six types of Oshima tsumugi silk used for the tiles are called “Shiro Oshima tsumugi” (white Oshima tsumugi silk), which is woven by combining colorfully rubbed kasuri yarn and plain white yarn.

They offer a relaxing bath time with a new fascination for Oshima tsumugi.

Feature 3: “Oshima tsumugi” scattered throughout the guest rooms, creating a unique space

The first thing you will encounter is the mud-dyed handle of the entrance door.
The walls of the deep hallway are lined with upcycled Oshima silk and artwork depicting the nature of Amami.

Other cultural and high quality elements are chicly scattered in the guest rooms, creating a one-of-a-kind space where you can feel the tradition and innovation of Amami.

Commendation comments received from the judges


▼From Kyoko Sekine (hotel journalist)
I was very impressed by Denpaku’s mission of “passing on village culture to the next generation. I agree wholeheartedly with the concept of “aiming to create a society in which no one is left behind” by putting grandmothers and grandfathers in the leading roles.
The spiral of “the hotel is not destroying nature because it is built,” but rather “the surrounding environment is improving because the hotel is built, and cultural activities are growing and developing along with the hotel. The spiral is no longer just a place to stay overnight. The strong belief of the representative is utilized in the creation of this facility.

 

Comments on the award (from Yasuhiro Yamashita, architect and representative of Amami Innovation Co.)


I had been traveling abroad as an architect for many years, and my experience in supporting earthquake disaster reconstruction efforts had led me to believe that I must protect my own countryside.
At that time, the residents of my hometown, Amami, requested that I work on vacant houses, and the business was born in 2016. Almost 7 years have passed, and the company has grown from 2 employees to over 100 employees today. Denpaku has only highly motivated employees, but they are all amateurs. We are not experts in lodging, tourism, or city planning, but we want to be the “ultimate group of amateurs. This is because we believe that the grandparents are the main actors and that they should be the ones with strong feelings to accompany them. Receiving such a gratifying award encourages all of us to move forward into a new world. Thank you very much.
We will continue to make it our mission to pass on “village culture” to the next generation, and through community development that “turns everyday life into tourism” in villages, we will move toward the realization of “a society where no one is left behind.

【Press Release】 Amami’s traditional boat is now available in a new form. A sunset cruising tour on the world’s one and only catamaran, “Denpaku Catamaran,” was born!

 

Denpaku” (Head office: Amami Innovation Co., Ltd., Amami City, Kagoshima Prefecture / President: Yasuhiro Yamashita), which is engaged in community development and operates retreat lodging facilities in the Amami Islands, has created an experience tour for guests of Denpaku The Beachfront MIJORA to enjoy a sunset cruise on “Denpaku Catamaran”. Sunset cruising in Akagi Bay was born. You can enjoy a rich moment immersed in the nature of Amami while watching the setting sun in front of Denpaku The Beachfront MIJORA.

“Denpaku Catamaran”, the only one of its kind in the world, was created in collaboration with Ryoichi Tsuboyama (59), the only boat builder in Amami who makes traditional wooden boats, and was designed and built in a way never seen before. In the past, wooden fishing boats called “taku-san” were a common sight in the Amami Sea, but they have become less common due to changes in the fishing industry and lifestyles.
With the birth of “Denpaku Catamaran,” we hope that this new form of traditional boat floating on the Amami Sea will help people learn more about the island’s traditional culture and natural beauty, and help to pass on traditional skills to the next generation.
Denpaku will continue to support the revitalization of local traditional crafts and the transmission of skills through the elimination of the lack of successors.

Denpaku Catamaran” Redesign of a traditional boat to make the sea more accessible and enjoyable


Denpaku, whose concept is to “pass on traditional and legendary architecture and village culture to the next generation,” has focused its attention on traditional Amami wooden boats. Currently, it is used in the “boat paddling race” that the Amami islanders look forward to every year, and is called “Ainoko-bune” on the island.

This boat was developed by an Amami boat builder in the Taisho era (1912-1926) by incorporating the advantages of the Okinawan wooden boat “Sabani”, which has excellent speed, into the wooden boat called “Itatsuke”, which has been used for fishing in Amami for a long time. The stable and fast performance of the boat made it popular among fishermen. However, as the fishing industry changed with the times, the number of traditional boats declined drastically. Mr. Tsuboyama is the only person in Amami who has inherited this shipbuilding technique.

Yamashita, the representative of “Denpaku” and an architect from Amami, did not want to see this traditional boat technology die out, so he designed the boat. Together with Mr. Tsuboyama, he worked for about a year to complete a boat that is “a new take on a traditional object, one that can only be found here in the world.
The stunning curvaceous beauty created by carefully bending wooden planks over time is a true expression of the high level of skill involved. By connecting two of these boats together in a luxurious manner, a sense of stability is maintained, creating space for cruising and other relaxing activities on the sea.

By implementing experience programs that “turn everyday island life into tourism,” including traditional local crafts, songs and dances, dialect, festivals, and local cuisine, Denpaku hopes to help spread valuable cultural resources and pass them on to the next generation.。

The Concept of Catamaran


Sparkling light and shimmering water
The warmth of handmade work and wood carries you along, and your heart will smile at the exciting time.

Till the falling sky connects to the sea
Fill your glass with the colors of the sunset and play with the scent of the tide and the water.

In a cradle floating on the mother sea
face to face with yourself, and slumber in the time of eternity.

Story of the inauguration of “Yasuhiro Yamashita and Community Development,” the official website of the group brand


From Yasuhiro Yamashita, Representative Architect

As an architect, I have created many buildings, specializing in the development of materials, structures, and construction methods. However, I began to feel a limit to what I could do with the “point” design of architecture, and gradually became interested in “urban development” that designs the “surface” of society, and after many years of research, I have been working hard to put this into practice in my hometown in the Amami Islands. Through various efforts, I have now thankfully grown from a “surface” to a “three-dimensional” structure with thickness.
We have come to believe that just as human beings are composed of 37 trillion cells, the connection between settlements forms cities and countries, and that the entry of outside information into these communities makes them healthy. We launched this brand site to contribute to the sustainability of the villages that need us, utilizing our experience cultivated in the Amami Islands.

 

Top page of the new brand official website

The official website of the group brand “Yasuhiro Yamashita and Community Development” will be launched on July 10, the anniversary of the establishment of “Atelier Tekuto”.

 

Vision of the new group brand official website

“We will listen to the small voices of the world’s villages,
We will create a town of beauty and health.
Bringing such innovation of happiness from Amami to the world.”

 

To support the development of eco-friendly retreat lodging facilities

We provide a one-stop service for the development of eco-friendly retreat accommodations that will create a region where people can earn money. We support development and operation methods appropriate for the region, from land search, design and supervision, consulting on lodging facility operation, producing local food and technology, and building regional partnerships, utilizing our past achievements and experience.

 

The Ideas Behind the Logo

The symbol mark of the newly created official website of the group brand continues to change. It was born from the idea that we are an organization that is constantly growing and cycling, and that we should be flexible enough to adapt ourselves to any form or thought in order to be close to the smallest voice.
The green color of the logo is also the color of the rich vegetation spreading in the Amami Islands. Just as plants produce nutrients through photosynthesis using water and light, the logo signifies the cycle of absorbing nature, materials, and local traditions to create a rich lifestyle for the community.
