Take an aerial stroll over the Oi River while tasting Shimada tea

Nanamagari Sky Park in the middle reaches of the Oi River is one of Japan's leading paragliding spots. Known as "Uyama no Nanamagari," you can enjoy an aerial stroll while looking at the large meandering Oi River and the tea fields that spread out on both sides of the river.
The instructor is Mr. Miyata, the World Cup paragliding champion.
"Paragliding Ippuku" is a unique activity where you can enjoy a tandem flight (two people) with Mr. Miyata, drinking green tea before, during or after the paragliding. Taking a break at an altitude of 700m is a valuable experience that can only be had in Suruga.
