Tenkubou (天空棒) was the last obstacle of the Final Stage in KUNOICHI 3-6. It was simply a pole 5 metres in length that competitors must climb and press the button to stop the clock. It didn't cause as many failures as it was expected. Miyake Ayako has climbed it three times in a row. It was removed in favour of the Climb Board in KUNOICHI 8 .
