On the evening of May 4, 2026, Okayama Castle will host something it has never seen before: hundreds of glowing sky lanterns drifting upward into the night, their warm light painting the iconic black castle keep in an ethereal glow. The inaugural Ujo Sky Lantern Festival marks a new chapter for one of Japan's most striking castles — and one of Golden Week's most photogenic new events.
A Castle Made for Drama
Okayama Castle, nicknamed Ujo (Crow Castle) for its distinctive black exterior, stands on the banks of the Asahi River in central Okayama. Originally built in 1597 by the feudal lord Ukita Hideie, the castle was destroyed in World War II and faithfully reconstructed in 1966. Its dark facade makes it a dramatic contrast to the white castles that dot Japan — and the perfect backdrop for floating lanterns.
The castle recently completed a major renovation in 2022, upgrading its interior museum and adding new lighting to the exterior. The sky lantern festival takes full advantage of these improvements, using the castle grounds and the adjacent Korakuen Garden riverbank as launch sites.
What to Expect
Participants purchase lantern kits at the venue (expected around ¥1,500–2,000 per lantern) and write wishes or messages on them before the coordinated release. At a designated time in the evening, hundreds of lanterns rise simultaneously — a moment of collective wonder as the glowing paper vessels ascend against the silhouette of the castle tower.
The event is modeled after the hugely popular sky lantern festivals that have captivated audiences across Asia, from Taiwan's Pingxi Lantern Festival to Thailand's Yi Peng. However, this being Japan, expect meticulous organization: safety measures, fire-resistant materials, and designated launch zones.
Supporting Events
The castle grounds will host food trucks and craft stalls throughout the evening, and the castle's interior museum will extend hours for the occasion. The adjacent Korakuen Garden — one of Japan's three most celebrated landscape gardens — may also offer extended evening access, making it possible to enjoy both the garden and the lantern release in a single visit.
Practical Information
Date: May 4, 2026 (Monday, national holiday — Greenery Day) Venue: Okayama Castle grounds, Okayama City Lantern Release: Evening (exact time TBA — typically around 7:30–8:00 PM) Admission: Free entry to grounds; lantern kits sold separately
Getting There
Okayama Castle is a 20-minute walk from JR Okayama Station, or a quick 5-minute ride on the Okaden streetcar to Shiroshita (Castle Below) stop. Okayama Station is a Shinkansen stop on the Sanyo line — 50 minutes from Shin-Osaka, 3 hours 20 minutes from Tokyo.
Making a Weekend of It
Okayama is perfectly positioned for a Golden Week mini-trip:
- Korakuen Garden — Right next to the castle, this Edo-period garden is at its lush green peak in early May. Budget at least 90 minutes to explore its lawns, ponds, and tea houses.
- Kurashiki Bikan Historical Quarter — A 15-minute train ride away, Kurashiki's canal district features white-walled warehouses, the excellent Ohara Museum of Art, and charming cafes. An essential day trip.
- Kibitsu Shrine — The shrine said to inspire the legend of Momotaro (Peach Boy), Okayama's mascot. Its 400-meter covered corridor is stunning.
- Okayama's fruit — The prefecture is famous for white peaches and Muscat grapes. Golden Week is early for peaches, but the local fruit parfaits at cafes near the station are available year-round.
Tips
- Bring a camera with good low-light performance. The lanterns against the black castle will be incredibly photogenic, but it's a nighttime event. A smartphone with night mode works well.
- Arrive by 6:00 PM to buy your lantern kit, explore the food stalls, and secure a good spot for the release.
- Dress in layers. Okayama evenings in early May hover around 15–18°C once the sun sets.
- Book accommodation early. As a first-ever event during Golden Week, hotels will fill fast. Consider Kurashiki as an alternative base.
Why This Matters
First-ever events carry a special energy — the excitement of something untested, the community pride of launching a new tradition. The Ujo Sky Lantern Festival has the ingredients to become an annual highlight: a visually stunning venue, a universally appealing format, and prime Golden Week timing. Being there for the inaugural edition means witnessing the birth of what could become one of western Japan's signature spring events.
