The Future of Earth and Biodiversity Week
TUNISIA OVOP DAY: Roots & Wings
Republic of Tunisia
The thesis of this event is that OVOP: One Village, One
Product « Isson-Ippin », a concept born in Japan in the
1980s, represents a mechanism for endogenous and
decentralized development. OVOP initiatives may involve
agricultural and non-agricultural products, tangible and
intangible goods, traditional or innovative activities. The
philosophy of OVOP is rooted in the valorization of
biodiversity, local natural resources, know-how, traditions,
identity, and the geo-cultural heritage of communities. OVOP
Day will highlight both the Japanese and Tunisian
experiences in implementing this concept.
OVOP Day will particularly explore the potential of Tunisian
olive oil in its dual dimension. On the one hand, it
emphasizes the roots dimension: heritage, biodiversity,
territorial and cultural identity. On the other hand, it
highlights the wings dimension through PIST (Partnerships in
Innovation, Science, and Technology) to identify and enhance
its multiple virtues, whether culinary, cosmetic, or
therapeutic.

【Reflection】
The Tunisia OVOP Day: “Roots & Wings”, held on 25
September 2025 at the Theme Weeks Studio during the thematic
week “The Future of Earth and Biodiversity”, was one of the
key highlights of Tunisia’s participation in Expo 2025 Osaka.
Inspired by Japan’s One Village, One Product (OVOP)
philosophy, originally born in Oita Prefecture in the 1980s,
the event successfully connected Tunisian and Japanese
experiences in local development, biodiversity valorization,
and innovation.
Mr. Setuso Iuchi, President of the Osaka Chamber of Commerce,
who highlighted the importance of the Tunisian–Japanese
partnership in promoting sustainable and inclusive growth,
delivered the day’s opening remarks.
The first panel revisited the origins and philosophy of OVOP,
with insightful contributions from Mr. So Sato (Representative
of Oita Prefecture), Dr. Takafumi Ueda Senior Advisor, JICA),
Mrs. Hanene Ayadi Labidi (Director, APIA Tunisia), Prof.
Motohiro Kurokawa (Takasaki University of Economics) and Mr
Nadhir Bessaoud Nadhir made his presentation on behalf of a
Tunisian- Japanese team of young students from TBS of
university of Tunis and Takasaki City University of Economics.
He presented their joint project to dry kaki grown in
Ouechtata,Tunisia, and promote it as an OVOP product of that
région.
Discussions highlighted OVOP as an effective framework for
decentralized regional development, empowering local
producers, promoting biodiversity-based industries, and
linking traditional knowledge with modern innovation.
The second panel focused on Tunisian olive oil as a living
heritage and a sacred Gift of Mediterranean symbol of
biodiversity and sustainability. Renowned experts, including
Prof. Hiroko Isoda and Prof. Mitsutoshi Nakajima (University
of Tsukuba), Prof. Hamza Essaddam, and Dr. Darine Dogui
(National Institute of Consumer Affairs– Tunisia), explored
its nutritional, cosmetic, and therapeutic properties,
underscoring the scientific and economic potential of this
emblematic product.
The third panel, led by author Malek Labidi, offered a
cultural and gastronomic exploration through her book
“Tunisia’s Olive Oil: Liquid Gold”, prepared especially for
Expo 2025 Osaka. The publication celebrates the history,
identity, and versatility of Tunisian olive oil as both a
heritage product and a driver of sustainable innovation.
Strong synergies were also underlined between Onsen Tourism,
the focus of Onsen Day held on 25 June and the OVOP movement,
as both emphasize community-based development, wellness, and
the valorization of local natural resources. Mr. So Sato
expressed his intention to support an exchange initiative
between Beppu (Oita) and Korbous (Tunisia), while Mr. Takafumi
Ueda (JICA) informed Mrs. Hanene Labidi of his plan to visit
Tunisia. Moreover, Ms. Nami Suzuki, a Japanese Onsen owner
from Beppu and partner of Dr. Kojo in Synapse Therapy,
confirmed a visit to Tunisia in November 2025 to explore
cooperation in wellness tourism.
Finally, a joint Follow-up and Reflection Day will be
organized in Tunisia to build upon the results of both the
Onsen Day and OVOP Day, gathering public, private, academic,
and civil society stakeholders to expand collaboration. The
presentations by Prof. Isoda and Prof. Nakajima on Tunisian
olive oil will also be revisited at CEPEX during their next
visit to Tunisia, scheduled for January 2026.
【Post EXPO Initiatives】
Building on the success and partnerships established during
Tunisia OVOP Day, Tunisia aims to sustain and deepen the
dialogue initiated at Expo 2025 Osaka through several concrete
follow-up actions.
First, Tunisia plans to collaborate with Oita Prefecture,
JICA, and Japanese academic institutions such as the
University of Tsukuba and Takasaki University of Economics to
adapt the OVOP approach to Tunisia’s regional context. This
initiative will seek to empower local communities, promote
biodiversity-based industries, and integrate traditional
knowledge into innovation-driven local development
policies.
A direct outcome of the exchanges in Osaka is the proposed
cooperation between Beppu (Oita) and Korbous (Tunisia),
focusing on wellness tourism and natural heritage valorization
a continuation of the “Onsen Day” spirit and its synergy with
the OVOP movement. Both initiatives share the same goal:
revitalizing local economies through the sustainable use of
natural and cultural resources.
JICA’s Senior Advisor, Mr. Takafumi Ueda, has expressed his
intention to visit Tunisia to explore cooperation prospects
under the OVOP framework, particularly in connection with the
Agricultural Investment Promotion Agency (APIA) and CEPEX.
Likewise, Ms. Suzuki, Onsen owner from Beppu and partner in
the Synapse Therapy initiative, plans to visit Tunisia in
November 2025 to identify collaboration opportunities in
wellness and health tourism.
In addition, a Joint Reflection and Follow-up Day will be
organized in Tunisia, gathering participants and stakeholders
from both the Onsen Day and OVOP Day. This meeting will bring
together public institutions, private sector representatives,
academia, and civil society to consolidate partnerships and
define the roadmap for future actions.
From a research and innovation perspective, discussions are
underway between Tunisian institutions and the University of
Tsukuba to launch a joint research project on the nutritional,
cosmetic, and therapeutic properties of Tunisian olive oil.
The planned visit of Professors Isoda and Nakajima to Tunisia
in January 2026 will provide an opportunity to continue this
scientific collaboration and to present their findings at
CEPEX.
Finally, CEPEX intends to integrate the OVOP model into its
export promotion strategy, including showcasing Tunisian OVOP
products at international events, promoting the book
“Tunisia’s Olive Oil: Liquid Gold” as a flagship publication,
and organizing thematic seminars on biodiversity, circular
economy, and innovation.
Through these initiatives, Tunisia seeks to extend the legacy
of Expo 2025 Osaka and to position itself as a proactive and
visionary partner in advancing sustainable, inclusive, and
locally driven development inspired by Japan’s OVOP
philosophy.
