Visitors joined OliOli and got creative as they put their architectural skills to test. Kids decorated their own piece of the structure before climbing through the tunnels and finding the best hiding places.

This activity took place on the ground floor of building 9 (opposite Akiba Dori) and was on a first-come-first-serve basis up to a max 10 participants, no pre-registration required. It was recommended for ages 5+.

It was free of charge and sessions last 20-25 minutes and started at the beginning of each hour.
