A Sentry Box from a Palace Gate
At Meiji Mura, the open-air architecture museum on the hills above Inuyama in Aichi Prefecture, one of the smallest structures rewards the closest attention. The Akasaka Detached Palace Main Gate Guardhouse covers a footprint of only about two square meters. It is an octagonal wooden sentry box, built in 1908 to stand beside the ceremonial gate of what was then the Crown Prince's Palace in Tokyo, the building known today as the State Guest House, Akasaka Palace.
Four of these guardhouses once flanked that gate, two outside and two within, where palace guards kept watch. This single example was dismantled and moved to Meiji Mura in 1983, then rebuilt on the museum grounds. Its parent palace still stands in Tokyo, and in 2009 it received the country's highest cultural ranking.
Registered, Not Designated
Japan protects historic buildings through two parallel systems, and the distinction matters here. The State Guest House is a designated National Treasure, the top rank reserved for properties of exceptional national value. The guardhouse carries a lighter status: Registered Tangible Cultural Property, a category created in 1996 to protect a wider range of structures, especially buildings from the modern era that might otherwise fall outside the older designation system.
The guardhouse was registered on December 1, 2003, under registration number 23-0067. The reason given was that it serves as a model of design. A working sentry box received the same decorative attention as a state monument, and that small ambition is what the registration recognized.
Reading the Details
The building repeats, in miniature, the classical vocabulary of the grand gate it once accompanied. Its eight walls are finished in white paint, inside and out. A semicircular arch frames the entrance, and round windows pierce the walls. Along the eaves run a cornice, a band of dentils, and a Greek key, the angular repeating pattern also called a meander.
Above sits a domed roof sheathed in copper. At its peak, a scrolled ornament is wrapped with a carved garland and capped by a sphere. Stand close and the contradiction becomes clear: a structure with room for a single standing guard was given the ornamental care of a palace.
Katayama Tokuma and the Palace
The palace and its gate were designed by Katayama Tokuma (1854–1917), one of the first four graduates of the architecture course at the Imperial College of Engineering, where the British architect Josiah Conder trained Japan's earliest professional architects. Katayama joined the Imperial Household Ministry and became the leading designer of court and public buildings, with the Imperial Nara Museum and Imperial Kyoto Museum among his works.
For the Crown Prince's Palace he traveled through Europe and North America, taking inspiration from the Palace of Versailles and the Louvre. Completed in 1909, the palace is often described as Japan's only Neo-Baroque palace. The guardhouse, finished the year before, was shaped to sit in harmony with that ornate gate.
Around Meiji Mura
Meiji Mura opened in 1965 to rescue buildings from the Meiji era (1868–1912) that were being torn down as Japan rebuilt itself. More than sixty structures now stand across its grounds beside Iruka Pond, among them eleven Important Cultural Properties. The most famous is the central entrance hall of the old Imperial Hotel, designed by the American architect Frank Lloyd Wright and reassembled here piece by piece.
A vintage steam locomotive and an old Kyoto streetcar still carry visitors between sections of the village. The castle town of Inuyama lies close by, and Inuyama Castle, one of only a handful of original keeps ranked as National Treasures, sits about half an hour away.

Q&A
- Can I go inside the guardhouse?
- It is a tiny one-person sentry box with no usable interior, so there is nothing to enter. You can walk all the way around it, which is the best way to study the arched doorway, the round windows, and the ornament on the roof.
- Is this the original building or a copy?
- It is the original 1908 structure. It was taken apart in Tokyo and rebuilt at Meiji Mura in 1983, which is how many buildings here were preserved.
- Can I also see the palace it came from?
- Yes. The State Guest House, Akasaka Palace, stands in central Tokyo and opens to the public for much of the year, though tours pause when official guests are received. Confirm dates on its official site before planning a visit.
- How do I reach Meiji Mura?
- From Nagoya, take the Meitetsu line to Inuyama Station and a bus from the east exit to the museum. Buses also run from central Nagoya. Many visitors come by car, since bus frequency is limited.
- When is the museum open?
- Hours change with the season, roughly 9:30 to 17:00 from March through October and 10:00 to 16:00 from November through February. The grounds are large, so allow most of a day. Check the official site for closures and maintenance days.
