"Oyado The Earth" Commitment to 21st Century Environmental Coexistence Development

In 2008, Oyado The Earth, a ryokan (traditional Japanese inn) based on the concept of coexistence with the environment, was established in Ishigami-cho, Toba City. Based on the concept of coexistence with the environment, the ryokan is engaged in development aimed at preserving the natural environment and promoting the sustainable development of local industries. The goal is to ensure that future development in rural areas is welcomed and that the development itself contributes to the preservation of the natural environment and the promotion of local industries.

With the theme of developing a 21st century (future-oriented) accommodation model, we have set the following conditions and will work through companies to contribute to nature conservation and regional industry.

• 1.More than 90% of the acquired area will be left as natural forest to preserve the local ecosystem (currently, 5% of the development site is natural forest).
• 1.Rather than discharging domestic wastewater directly into the ocean, it is purified and then infiltrated underground to prevent marine pollution. (Evaporation-transpiration underground infiltration system).
• 1.By electrifying all cooking, hot water supply, and air conditioning within the facility, CO2 emissions can be reduced to zero.
• 1.Food waste generated during business operations is not taken outside the premises but recycled (this has been ongoing for 17 years since the business opened).
• 1.All recyclable waste is sorted and recycled (a practice that has been ongoing for 17 years since the company's establishment).

In 2012, we launched the (Black Abalone Release Project) to commemorate our 5th anniversary. This initiative aims to preserve the traditions of the "Ama" divers in Toba City, known as "Japan's number one Ama town." In collaboration with the Mie Prefecture Aquaculture Center and the Toba Isobe Fisheries Cooperative Association, we are releasing black abalone larvae into the sea alongside the "Ama" divers of Ijika Town, implementing various measures to prevent damage from predators. As of May 2025, we have completed the 14th release. As a result of these efforts, the black abalone catch in Ijika Town has recovered to nearly the same level as its peak since 2019.

Food waste generated by the business is recycled rather than taken outside the facility (food waste recycling).

• 1.Thorough food procurement and preparation based on the number of reservations

  The reservation desk keeps track of the latest number of reservations every day and shares this information with the kitchen in real time.

• 2.CO2 reduction effects of introducing food waste disposal machines

  The introduction of food waste disposers has significantly reduced CO2 emissions generated during incineration and transportation compared to conventional food waste disposal methods.

• 3.Our inn's food recycling loop

  We work with contracted farmers to utilize the waste produced by our food waste disposal machines as compost.

Sewage treatment system "Evaporation and underground infiltration type"

• Wastewater treatment using a septic tank and a natural filtration system called "evaporation and underground infiltration."

  By passing through a natural filtration system using a five-stage terraced field method, even trace amounts of pollutants that cannot be completely removed by septic tank treatment are thoroughly removed. The water that is ultimately returned to the sea is extremely clean, with high transparency, and does not burden the surrounding ecosystem.
