English: The Sōketsu-tei, the largest one of the former teahouses of Nagoya Castle, was built in the Sukiya style. In an excavation survey, a site almost exactly matching that of the Soketsu-tei as depicted in Oniwa Ezu, the historic plan of the old castle garden, was identified. Today, cobble stones are placed to mark where tatami mats would have been, rubble and plaster where the hallway was, and gravel on the other surfaces for an easy understanding of the original structure.
