The Tatami Hall is located in Jämeräntaival 5 A but you can also access it via the Dernecon meeting facility in stairwell B. In addition to the tatamis, the Tatami Hall also has gym balls, a punching bag and a CD player. The Tatami Hall is available from 10am-11pm. Since the space is rarely required for an entire day, it is usually reserved in 2-hour slots.
The Tatami was renovated in 2019.
