Revolutionizing Olive Leaves: A New Organic Tea from Japan's Gunma Prefecture

Introduction to Whole Earth Olive Tea

In a remarkable leap for innovative beverages, Company Forestfree, led by President Yumiko Waguri and based in Taito Ward, Tokyo, has unveiled a new product that’s set to transform the market:

Whole Earth Olive Tea. Available from July 22, 2026, this non-caffeinated tea is made entirely from 100% organic olive leaves sourced from Gunma Prefecture. The product uses the expertise of Japanese tea-making techniques to create a drink that is not only consumable every day but also packed with the health benefits of olive leaves.

The Significance of Olive Leaves

Olive leaves have often been overlooked in favor of the more commercially popular olive oil, but they are rich in a powerful polyphenol known as oleuropein, which is known to be even more abundant in leaves than in the olive fruit itself. With a few companies in Japan bringing olive tea to the forefront, it is now being touted as the next rooibos tea, offering an alternative for those seeking caffeine-free options.

With a deep focus on the uniqueness of the olive leaf, Forestfree aims to communicate its health benefits to consumers through engaging storytelling and direct interaction with local farmers, bringing a new level of value to this underutilized resource.

Bridging Gaps with Local Resources

The olive leaves used in the Whole Earth Olive Tea are cultivated in the lush fields of Tatebayashi, Gunma Prefecture. Traditionally, the olives are harvested primarily for oil production, often leaving the leaves unused. By focusing on the delicious and health-promoting aspects of olive leaves, Forestfree seeks to innovate and elevate regional agricultural resources.

Moreover, within their sustainable farming practices, the company incorporates methods like utilizing coffee grounds from major coffee chains as compost and repurposing waste from olive oil extraction as cattle feed. This commitment to a circular agricultural model showcases their holistic approach to environmental sustainability.

Setting a New Standard for Caffeine-Free Teas

Rooibos tea has been widely celebrated for its caffeine-free properties in recent years, and Forestfree is poised to fill the niche for the next wave of non-caffeinated teas. The tea is crafted from rare tea varieties that have undergone an extensive six-year selection process amongst over 1,000 types, resulting in a product that minimizes bitterness and grassy notes.

Its smooth, mild flavor pairs well with meals, making it perfect for after-dinner relaxation while being a healthy addition to anyone's beverage choices.

The Health Benefits of Oleuropein

What sets this product apart is the significant concentration of oleuropein it contains—about 1,100 times more than the typical amount found in olive oil, with 12.6g per 100g. Research has indicated that oleuropein possesses antioxidant, anti-inflammatory, and antimicrobial properties. Studies are ongoing regarding its effects on cardiovascular health, metabolism, and even beauty treatments. Additionally, since the company offers 100% organic, additive-free tea, consumers can enjoy the maximum nutritional benefits.

Unearthing Culinary Stories

At Forestfree, their mission revolves around unearthing the stories behind food products and sharing them as a valuable narrative with the public. Through engagements with producers across the nation, they aim to bring forth the rich history, challenges, and passions that underscore their offerings, acting as a 'bridge' to connect these local stories with consumers both in Japan and internationally.
