May in Japan is a time of celebration, nature, and deep cultural significance. As the country transitions from spring to early summer, the weather is pleasant, the landscapes are lush, and numerous traditional events take place across the nation. Here are 9 unique seasonal sights and traditions you should experience during your trip to Japan in May.
1. Children’s Day (Kodomo no Hi) – May 5th

Colorful koinobori (carp streamers) flutter in the breeze to celebrate the healthy growth and happiness of children. Traditional displays include miniature samurai armor and sweet rice cakes wrapped in oak leaves.
2. Golden Week Festivities

Japan’s long holiday period around early May is filled with family travel, festivals, and sightseeing. Although busy, it’s a great time to see locals celebrating.
3. Vivid Green Landscapes (Shinryoku)

Mountains and parks turn a fresh, vibrant green. Perfect for hiking, picnics, and scenic photography, especially in areas like Nikko, Hakone, or Kyoto’s Arashiyama.
4. Wisteria and Azalea Blossoms

Gardens and temples are painted with purple wisteria and vivid azalea blooms. Visit Ashikaga Flower Park or Nezu Shrine in Tokyo for a floral paradise.
5. Iris and Peony Flowers

In mid to late May, iris gardens and peony blooms become must-see destinations. Their delicate colors symbolize early summer elegance.
6. Rice Planting Season

Rural areas begin taue (rice planting). The sight of reflective paddies in the countryside is both peaceful and photogenic—especially in Niigata or Okayama.
7. Shobu-yu (Iris Bath)

A traditional bath infused with iris leaves is believed to bring good health and ward off evil. Some onsen offer this experience in early May.
8. Tide Pooling and Shell Gathering (Shiohigari)

Join locals on beaches to hunt for clams during low tide. It’s a fun cultural experience—try it in Chiba, Aichi, or Fukuoka!
9. First Bonito (Hatsugatsuo)

Try the seasonal delicacy—first-catch bonito (skipjack tuna)—served as sashimi or tataki. Fishermen bring in the prized fish from southern waters around May.
Bonus Tip:
Book accommodations early during Golden Week, and try to visit less crowded local spots for a more intimate cultural experience.
