How The Evening Program Works

Families search inside the museum for hidden boxes, collect clues, and solve the final answer. The official event page says every participating child receives a prize, and children must be accompanied by a parent or guardian.

Children who join the treasure hunt receive hand-held fireworks for the supervised activity at the water basin on the museum lawn. Visitors may not bring their own fireworks, so do not arrive carrying outside pyrotechnics.

Daytime And Event Hours Are Separate

The museum’s regular hours are listed as 9:00 AM-5:00 PM with final daytime admission at 4:30 PM. The event begins at 5:00 PM and the wider evening program continues until 8:30 PM.

A traveler planning both the standard exhibition and the evening activity should distinguish the museum’s normal admission window from the separate event schedule and fees. Arrive early enough for the daytime galleries rather than expecting regular entry after 5:00 PM.

Plan For Cash, Darkness, And The Return Trip

The event fee is cash only. Evening temperatures at the Fuji foothills can fall quickly in September, so families should carry a light layer and use the illuminated routes rather than walking across dark landscaped areas.

The museum lists free parking on site and at Roadside Station Fujiyoshida. Travelers without a car should confirm their return bus or taxi plan before joining because the event finishes after the museum’s normal daytime closing time.

Traveler Actions

  • Bring cash for the participation fee; card payment is not listed for the event.
  • Arrive before 7:30 PM for the treasure-hunt final reception.
  • Keep children with a parent or guardian throughout the activity.
  • Do not bring outside fireworks; the supervised activity supplies them to participating children.
  • Check the evening return plan and bring a light layer for cooler foothill temperatures.
