Nara Prefecture's Official VTuber "Nanaka" Launches SNS Campaign! (7th Prize: New Nara-grown Watermelon Variety "Golden Jack")

Nara Prefecture is implementing an SNS-linked giveaway project, "Nanaka's Gift to Everyone! Sharing Nara's Charms Campaign!" in fiscal year 2025, utilizing the official X (formerly Twitter) account of the prefecture's public relations VTuber, "Nanaka (ななか)".

This campaign, launched in March 2024 with the debut of VTuber Nanaka, introduces Nara Prefecture's specialty products and regional resources on social media, with original Nara Prefecture goods and other prizes offered to winners selected by lottery.

The campaign aims to attract interest in Nara Prefecture and promote awareness and understanding of prefectural administration by leveraging the appeal of Nanaka's official X account.

◆ The 7th Prize is... A New Nara-grown Watermelon Variety: "Golden Jack"!!

"Golden Jack," a new variety of watermelon, was registered in 2025 by a seed and seedling company in Nara Prefecture.

It is a seedless watermelon with a striking contrast between its jet-black rind and lemon-yellow flesh. It features a smooth texture with low fiber content, a firm and solid flesh, and a stable, pleasant taste with high sugar content.

The 7th prize product is "Golden Jack"!

◆ The Delicious Relationship Between "Nara Prefecture" and "Watermelon"

From the Meiji to Taisho eras, Nara Prefecture was known nationwide as a major production center for "Yamato Suika," a watermelon highly popular across the country for its sweet flesh and durable rind suitable for transportation.

While watermelon cultivation spread and production centers diversified nationwide after the period of high economic growth, the techniques and know-how related to varietal improvement and seed production have been passed down within the prefecture.

Currently, approximately 80-90% of watermelons nationwide are grown from seeds shipped by seed and seedling companies in Nara Prefecture, making Nara Prefecture a vital player in supporting watermelon cultivation across the country.

We invite you to experience the appeal of "Golden Jack," born from the varietal improvement techniques cultivated in Nara Prefecture over many years and its rich history.
