The Nagoya Castle Honmaru Goten Palace was built in 1615 by Ieyasu Tokugawa, the first shogun of the Tokugawa Shogunate, for his 9th son Yoshinao. Along with the Nijo Castle's Ninomaru Goten Palace in Kyoto, it was a representative of a traditional Japanese architecture called "Shoin-Zukuri".
Yoshinao and his family lived here for more than five years. A part of the building was rebuilt in 1634 when the third shogun Iemitsu Tokugawa visited Kyoto, but after that, it was rarely used as accommodations for the shogun and remained closed until the Meiji Restoration in 1868.
In 1930, before the war, it was designated as a national treasure along with the castle tower ahead of Himeji Castle and Nijo Castle as a World Heritage Site. If it had remained, it must have been a World Heritage site as well, but it was burned down by US air raids in 1945, near the end of World War II. Before the air raid, a large part of the building was measured and photographed, and the Japanese sliding doors with paintings had been evacuated and stored in other places. That made possible an accurate reconstruction, and it was opened to the public in 2018. However, other place, where most of them were stored, was not a remote place but a warehouse located across the moat inside the Nagoya Castle. In Japan, both in the past and now, the awareness of risk management for cultural properties is either lacking or insufficient. It seems that the screen paintings of the Honmaru Goten Palace just happened that the fire did not spread.
In the rebuilt palace, the Japanese sliding doors with paintings and engravings in vivid colors were inlaid among the plain wood with the scent of wood, creating a calm and gorgeous atmosphere. Those conveyed that the previous palace before burning down had not been spared the expense and been a special cultural property. As for the restoration, while taking measures to withstand earthquakes in the parts that could not be seen, the parts that appeared on the surface were not half-baked in a modern style. The total construction cost was 15 billion yen, of which 5 billion yen was donated by citizens. It's just Nagoya, which spends money properly when necessary.
Cultural properties in Kyoto and Nara have fallen and faded after hundreds of years, but the Honmaru Palace conveyed what a freshly born space was like when such cultural properties were completed. I took it for granted that the timeworn elegance of an old building was Japanese architecture, but the Honmaru Palace was completely different, youthful, and fresh. I noticed that Japanese architecture was the architecture of the time, in which such a feature eventually obtained the sense of wabi-sabi (the aesthetic sense in Japanese architecture with transience and imperfection).
The Honmaru Palace also visualizes the fact that Japanese Shoin-zukuri architecture is an expression of ranking. The subjects of the paintings on the screen paintings were decided according to the ranking of the room, from Sojyu (animal), Kacho (flower and bird), and people, to Sansui (landscape). The technique also shifted from a color painting on a gold background for the low rank to an ink painting for the highest rank. The low-ranked entrance and corridor used a board and batten ceiling meanwhile the higher-ranked Omote Shoin Hall and Joraku-den Hall used the higher-ranked coffered ceilings. The ceiling also developed into a raised double fold-up style, and the panels on the ceiling became more gorgeous with lacquer work.
The Honmaru Goten Palace was rarely used for a long time, but the interior of the rooms that visitors were led into clearly showed their status and relationships with their masters, so it looks pretty faithful to the manners of the rank in Shoin-zukuri architecture. In the manners that showed the rank, the screen painting becomes more serene as the rank rises, while the ceiling becomes more luxurious, and the vector is the opposite. Was that the way to keep a balance?
Even so, the sense of the USA (and Russia), which easily destroyed top-class cultural properties that were not military facilities, needs to be verified.
