Another feature is the pit below the stage, which is now 16.45 metre (54 feet) deep — nearly four times what it was. The pit allows for props, actors and scenery to emerge from the bowels of the building.

Despite the high-tech fixes, the theatre retains many elements of the original interior as well as the facade, which evokes medieval Japanese castles and temples with its curved roofs and red paper lanterns.

In the 400-year-old stylised performing art, all-male casts perform in extravagant costumes and mask-like facial makeup.

The new four-storey playhouse, with an 1,800-seat capacity, is the fifth version of the theatre, whose history dates back to 1889.

The previous building, erected in 1951 to replace one heavily damaged in World War II, was demolished in 2010 due to worries over its ability to withstand earthquakes.

The theatre is now housed in a 143-metre (470 feet) skyscraper, the tallest building in the area.
