About the "Tomtom" Playground

Name: "Tomtom" (tomtom) — meaning "to shine brightly" in the Ainu language

Concept: Nature that supported Ainu livelihoods
Area Theme: Traditional living spaces — fishing in waterside communities

Feature 1: Original Composite Play Equipment Inspired by Ainu Culture

Boat-themed children's playground equipment

The playground features unique composite equipment with motifs drawn from Ainu cultural life:

  • Children's equipment inspired by a boat: The "itaomachip," used by the Ainu for fishing in the sea and large rivers, was a distinctive dugout canoe reinforced with wooden boards bound together to deflect waves. The equipment is shaped to evoke a boat cutting through the waves.

  • Toddler equipment inspired by salmon: Salmon was the most important fish for the Ainu — a staple food with every part used and nothing wasted — and was revered as "the divine fish." The equipment is shaped to evoke salmon swimming upstream.

Feature 2: Surrounded by Morewu, Traditional Ainu Patterns

The entire playground area is enclosed by the Morewu (spiral pattern), a traditional Ainu design. The pattern incorporates Kirau (meaning "horn" in Ainu), which is said to ward off evil — a symbol of the wish for children to play safely.

Feature 3: Inclusive Play for All Children

Pathways, gradients, and materials have been carefully considered so that all children, including wheelchair users, can play together. Playful elements are incorporated throughout the space to encourage interaction regardless of ability.

Location and Construction Overview

The playground is situated in the lawn area in front of the Experience Learning Center within the Upopoy grounds. Construction ran from September 2025 through April 2026, resulting in a total area of approximately 1,541 square meters.
