Nagai City Spring and Hot Air Balloons

  • Ayame Park: Nagai's symbol โ€” about 200 varieties of Japanese iris bloom Juneโ€“July
  • Nagai Shiroto Festival (Shiroto River Cherry Blossoms): April cherry blossom site
  • Shiroto Riverside Walks: Strolling through pastoral farming scenery

Ayame Park

  • Best Viewing: Mid-June to early July
  • Scale: Approximately 200 varieties and 500,000 Japanese irises
  • Ayame Festival: Nagai Ayame Festival held during the bloom period

Getting There

  • Alight at JR Yonesaka Line Nagai Station (about 1 hour from Yamagata via Flower Nagai Line)
  • About 5 minutes by car from Tohoku Chuo Expressway Nagai IC

Tips

Ayame Park is one of Eastern Japan's finest Japanese iris sites. Flowers blooming in rainy season rain are also atmospheric. Arriving by the charming local "Flower Nagai Line" is also recommended.
