When Tokyo's crowds start to feel overwhelming, the Shonan coast offers the perfect antidote — salt air, ocean views, and a pace of life that's distinctly more relaxed. In mid-March 2026, the area around Enoshima and neighboring Saitama delivers a one-two punch of spring festivals and fireworks that make for an unforgettable day trip (or weekend escape) from the capital.
The 43rd Shonan Enoshima Spring Festival — March 14–15
The 43rd Shonan Enoshima Spring Festival (第43回湘南江の島春まつり) is one of the region's beloved annual traditions, marking the unofficial start of the beach season along the Shonan coast. Held in and around Enoshima, the tiny island connected to the mainland by a bridge, this two-day celebration brings together locals and visitors for a lively kickoff to spring.
What to Expect:
- Traditional mikoshi (portable shrine) processions through Enoshima's narrow streets
- Taiko drumming performances along the harbor
- Local food stalls serving Shonan specialties: shirasu (whitebait) rice bowls, grilled shellfish, and fresh seafood
- Cultural performances including traditional dance and music
- A festive atmosphere with locals in traditional dress
The Enoshima Experience: Even without the festival, Enoshima is one of the most rewarding day trips from Tokyo. The island packs a surprising amount into its compact size:
- Enoshima Shrine — A network of three shrines dedicated to the goddess Benzaiten, connected by escalators and walking paths through lush greenery
- Samuel Cocking Garden — A botanical garden with the Enoshima Sea Candle observation tower, offering 360-degree views of Sagami Bay and, on clear days, Mount Fuji
- Iwaya Caves — Sea caves at the southern tip of the island with a mystical atmosphere
- Chigogafuchi — A dramatic rocky coastline where you can watch the sunset behind Fuji
Food Not to Miss: Shonan's signature dish is shirasu-don — a bowl of rice topped with tiny, translucent whitebait fish, either raw (nama shirasu) or lightly boiled (kamaage shirasu). The fishing boats come in during the morning, so the freshest bowls are served at lunchtime. You'll find shirasu restaurants lining the bridge approach to Enoshima and along the island's main shopping street.
Moominvalley Park Lake Fireworks — March 14
Just an hour north of Tokyo in Hanno, Saitama, Moominvalley Park celebrates its 7th anniversary with a special lakeside fireworks show on the evening of March 14. This isn't your typical summer fireworks display — it's an intimate, early-spring spectacle reflected in the still waters of Lake Miyazawa.
What Makes It Special:
- Fireworks choreographed to music, launched over the lake for stunning reflections
- The Moomin-themed park provides a whimsical backdrop you won't find anywhere else in Japan
- Early spring means crisp air and excellent visibility
- Significantly smaller crowds than summer fireworks festivals
The Park Itself: Moominvalley Park (ムーミンバレーパーク) recreates the world of Tove Jansson's beloved Moomin characters in a lakeside forest setting. Even if you're not a Moomin superfan, the park's Nordic-inspired architecture, nature trails around the lake, and cozy cafés make for a genuinely pleasant half-day visit. The adjacent Metsä Village is a free-entry shopping and dining area with a Scandinavian theme.
Getting There: From Ikebukuro Station in Tokyo, take the Seibu Ikebukuro Line to Hanno Station (about 50 minutes). From there, a bus runs directly to Metsä/Moominvalley Park (about 13 minutes).
Tip: Arrive in the afternoon to explore the park before the fireworks. Bring warm layers — March evenings in Saitama can be quite chilly, especially by the lake.
Building Your Coastal Spring Weekend
Here's how to combine both events into an ideal weekend:
Saturday, March 14:
- Morning: Take the Odakyu Line from Shinjuku to Katase-Enoshima Station (about 70 minutes, ¥640). Alternatively, the JR Tokaido Line to Fujisawa, then transfer to the Enoden Line — a charming local train that runs along the coast.
- 10:00–14:00: Explore the Shonan Enoshima Spring Festival. Walk the island, visit the shrine, climb to the Sea Candle tower, and have a shirasu lunch.
- 15:00: Head back to Tokyo via Shinjuku, then transfer to the Seibu Ikebukuro Line toward Hanno.
- 17:00: Arrive at Moominvalley Park. Explore the park and grab dinner at one of the cafés.
- Evening: Watch the 7th anniversary lakeside fireworks.
Sunday, March 15:
- Return to Enoshima for Day 2 of the Spring Festival, or explore other Shonan coast spots:
- Kamakura (15 min from Enoshima by Enoden): The Great Buddha, Tsurugaoka Hachimangu, and dozens of temples
- Hayama: A quieter beach town favored by the Imperial family, with excellent bakeries and cafés
- Chigasaki: Laid-back surf town vibes with views of Enoshima and Fuji from the beach
Practical Tips for the Shonan Coast
Best Trains:
- Odakyu Romance Car from Shinjuku to Katase-Enoshima: Reserved seats, large windows, and a direct ride. Worth the small supplement (around ¥630 extra).
- Enoden Line: The iconic green tram that connects Kamakura to Enoshima via the coast. It gets crowded on weekends — board at Kamakura for a better chance at a seat.
What to Wear: Mid-March on the Shonan coast is mild but breezy. Expect temperatures around 12–16°C during the day, dropping to 7–9°C in the evening. A light jacket and layers work best. Comfortable walking shoes are essential — Enoshima involves stairs and uneven paths.
Money: While major shops accept IC cards and credit cards, many festival food stalls and small restaurants are cash-only. Bring ¥5,000–10,000 in cash for food and small purchases.
Crowds: The Spring Festival draws locals more than international tourists, so it's lively but not overwhelmingly packed. For Moominvalley, weekdays are quieter, but the fireworks are Saturday-only.
Why This Trip Works
The Shonan coast represents a side of Japan that many visitors miss — the casual, coastal culture that locals love. It's neither the hyper-urban intensity of Tokyo nor the preserved historical beauty of Kyoto. It's families on the beach, surfers catching early spring swells, fishermen selling the morning's catch, and shrine festivals where the community comes together.
Combined with the whimsical surprise of Moominvalley Park's lakeside fireworks, this mid-March weekend offers a refreshingly different take on spring in Japan. No temple fatigue. No overwhelming crowds. Just the ocean, good food, and the first warm breezes of the year.
