For more information: https://en.fpp-japan.com

Immun'Âge for Winter Sports

Immun'Âge has been certified by "Informed Sports", an international anti-doping certification program, and highly trusted by the world's top athletes. Also, a joint study for professional athletes is being planned with Department of Orthopedic Surgery Nagoya City University Medical School in Japan.

In addition, Immun'Âge has been an official partner of Aston Martin Racing (AMR) for 20 years and research focusing on recovery was conducted with AMR racing drivers. Applying the findings from endurance racing and various researches to improvement of physical condition, a collaborative research with Nagoya University targeting professional bus drivers began in December 2024. Next spring, a large-scale joint research project will begin at Florida State University in the U.S., targeting the elderly in local community, with the aim of supporting not only motor sports but also those who want to enjoy driving safely for many years to come.

We are pleased to report that our annual carbon dioxide (CO2) absorption exceeded emissions from all manufacturing processes by 204.1 tons* in the last fiscal year, and achieveing "Carbon Positivity", which is one step beyond carbon neutrality. (*Calculated by our company at the end of August, 2024)

Eco-friendly Immun'Âge®

Carbon positive and carbon negative are interchangeable terms; carbon positive focuses on CO2 absorption (being positive), while carbon negative focuses on emission with the goal of removing CO2 (being negative).

■Immun'Âge® and Environmental Conservation Activities
Osato International Inc. is a maker of Immun'Âge®, that was born through combination of nature's blessing, papaya and its unique fermentation technique, located in the northern end of the Nobi Plain in Gifu, famous for the production of rose seedlings and Japanese persimmons called Fuyu-Gaki.  Immun'Âge® is made by the power of nature, and we believe that reducing environmental impact and preserving the neighborhood environment are important aspects of our corporate activities. As an example of our commitments, we have been certified under ISO 14001, the international standard for environmental management systems, for over 20 years, having received ISO registration in 2002 and successfully completed continuous renewal assessments.

We have been working to protect our neighborhood natural environment by managing the greenery and promoting recycling on our property. Osato Laboratory Inc., which is responsible for the production of Immun'Âge®, introduced solar power generation in 2014 and achieved carbon neutrality in three years through production by the solar energy. Additionally, after achieving carbon neutrality through the introduction of "Green Denki," a renewable energy source based on hydroelectric power in April last year, we attained carbon positivity in July 2024 by installing solar panels on the roof of Osato International Inc., allowing us to use electricity derived from natural resources.

Moreover, we launched the 'Firefly Village Creation Project' in 2009 as activities for local environmental conservation of fireflies, which live near human settlements and are considered indicators of health state of waterside environment. In this project, we have been managing and cleaning the grass along the stream that runs near the west side of our factory and educating local elementary school children for 'Lessons to think about the natural environment through fireflies'.

In 2012, the ORI WINE PROJECT was launched in response to a urgent request from the Ono Town Office regarding the effective use of persimmon fields that had become difficult to maintain due to aging farmers. The aim of this project is to create a new purpose in life for the local senior citizens as well as to revitalize the persimmon fields as vineyards for wine production. Experts from the University of California, Davis, a world authority on wine-making, visited the area to inspect the project and said the following: it would be impossible to cultivate European wine varieties like Pinot Noir and Chardonnay organically (without using chemical fertilizers or pesticides) in the hot and humid climate of Ono Town. However, we continued to challenge the harshness of nature, including the weather, molds and insects. Now, the project has grown to produce powerful additive-free red, white and rosé wines. In spring, the BIO vineyards are filled with dandelion flowers, butterflies, bees, birds, and even wild animals such as monkeys, deer, and rabbits that live in the neighboring mountains, creating liveliness reminiscent of a good old Japanese mountain village.

■Beyond Carbon Positivity, Contribution of Customers to the Environment through Immun'Âge®
The aforementioned "ORI WINE PROJECT" started from a small plot of 1,000m² and has now grown to an approximately 40,000m² with the cooperation of local community, the neighborhood senior, and elementary school children. This project also plays a major role in CO2 absorption. Last year, the total amount of CO2 absorption for our activities exceeded the amount of CO2 emissions from the manufacturing process by 204.1 tons per year (see references), achieving the goal of becoming carbon positive. Particularly noteworthy is the reduction of approximately 400g of CO2 emissions in terms of the manufacturing process for one box of Immun'Âge® (3g x 30 packets), and it has enabled to create our products through natural cycles.

Immun'Âge® has been aiming to protect wellbeing not only for human beings but also the natural environment, and that will lead to a better future for a long time to come. We are pleased to share that, through our activities, our customers now contribute to CO2 reduction by purchasing a box of Immun'Âge®. We will continue to make further efforts to support the "Longevity" for human and the Earth.

Immun'Âge^® × Green Electricity

■Immun'Âge^® : Being an Environmentally Friendly Product

ImmunʼÂge^® has been promoting to reduce environmental impact of the manufacturing process and become carbon neutral through planting to compensate for CO₂ emissions.

As part of this, Immun'Âge^® has been certified with ISO14001 specifying the requirements for an environmental management system to enhance environmental performance since 2002. We have created and maintained habitat for fireflies, Protecting Jewels of Night Project, by managing a stream running beside our company since 2009. Moreover, we give lectures for primary schools on environmental conservation around our neighborhood through protecting fireflies.

The ORI WINE PROJECT started in 2012 and we have re-cultivated abandoned farmlands due to aging of farmers as vineyards; local seniors would join together to stay physically and mentally healthy. The go-green project plays an important role both in active life for elders and absorbing CO₂ emissions.

Osato Laboratory Inc., responsible for the production of Immun'Âge^®, introduced solar power generation in 2014 and achieved carbon neutrality in three years; in April 2023, Osato International Inc. became carbon neutral by introducing Green Electricity that comes from 100% renewable sources (e.g., hydroelectric power). The environmental impact of production process has now achieved to zero!

■Immun'Âge^® : Aiming to Become Carbon Positive

Papaya, rich in nutrients and health benefits, attracts a great interest to scientists. Various traditional fermented food including miso, soy sauce, and natto have been taken on a daily basis since ancient times and well known as the secret to longevity in Japan. Immun'Âge^®︎ was made from the combination of two blessings from the nature.

Immun'Âge^®, made with the blessings of the nature, will continue to cope with the local through planting and other environmental conservation activities for pursuing carbon positive by further reduction of environmental impact.

The Ad of Immun'Âge® again appears this season on the trail map of the Shiga Kogen Prince Hotel / Yakebitaiyama ski resort in the northern part of Nagano Prefecture.
