Tsugaru Clan Mausolea: Five Sacred Halls Honoring the Lords of Hirosaki
Deep within the tranquil grounds of Choshoji Temple in Hirosaki, Aomori Prefecture, five wooden mausolea stand in a solemn row, silently honoring the lords and ladies of the Tsugaru clan. Known collectively as the Tsugaru-ke Tamaya (津軽家霊屋), these structures have witnessed over three centuries of history since the early Edo period. Designated as Important Cultural Properties of Japan in 1986, the mausolea offer a rare and evocative glimpse into the funerary architecture and spiritual traditions of one of northern Japan's most powerful feudal families.
The Tsugaru Clan and Choshoji Temple
The Tsugaru clan rose to prominence during the late Sengoku (Warring States) period, when Tsugaru Tamenobu consolidated power across the Tsugaru Plain in what is now Aomori Prefecture. After siding with Tokugawa Ieyasu at the Battle of Sekigahara in 1600, the clan was granted official domain status and began building Hirosaki Castle, completed in 1611 under the second lord, Tsugaru Nobuhira (also read Nobumaki).
Choshoji Temple was originally founded in 1528 at Tanesato (present-day Ajigasawa Town) as a family temple for the Tsugaru ancestors. In 1610, it was relocated to its current site alongside the construction of Hirosaki Castle. The temple was placed at the far end of Zenringai, a remarkable district of 33 Soto Zen temples gathered in a straight line along a cedar-bordered avenue. This arrangement served both spiritual and military purposes — Zenringai functioned as a defensive stronghold (known as the Choshoji Kamae) on the southwest flank of the castle, complete with earthen ramparts and moats.
The Five Mausolea: An Architectural Timeline
The five mausolea are aligned in an almost straight line to the south of the Mieido (Portrait Hall), each facing east and enclosed by a fence (tamagaki) with a gate at the front. Though built at different times spanning over a century, they share a common design: each is a two-bay structure with an irimoya (hip-and-gable) roof clad in thin wooden shingles (kokera-buki), entered from the gable end (tsuma-iri). The exteriors are of unfinished natural wood (shiraki-zukuri), giving them a dignified, understated appearance. Listed in order of construction date, the five halls are as follows:
Hekigan-dai (碧巌臺) — 1631
Built for the second lord, Tsugaru Nobuhira, this is the oldest surviving mausoleum in the group. It was constructed in 1631, shortly after Nobuhira's death. The exterior bears the Tsugaru family crest — the gyoyo-botan (peony with apricot leaves) — on each face. Inside, a stone muho-to (seamless memorial tower) is enshrined, and the mirrored ceiling features a vivid polychrome painting of a dragon.
Meikyo-dai (明鏡臺) — 1638
Dedicated to the consort of the second lord, known as Maten-hime, this mausoleum is uniquely decorated with the Tokugawa hollyhock crest (aoi-mon) rather than the Tsugaru peony. Maten-hime was the daughter of Matsudaira Yasumoto and a granddaughter adopted by Tokugawa Ieyasu himself. Her dramatic life — involving political marriages and succession disputes — has been the subject of novels and theatrical works. The ceiling painting here also depicts a dragon in brilliant colors.
Hakuun-dai (白雲臺) — 1656
This hall honors the third lord, Tsugaru Nobuyoshi. It is particularly notable because its ceiling painting depicts a celestial maiden (tennin) rather than the dragon motif found in the other four mausolea. The exterior displays the Tsugaru peony crest on all sides.
Kangetsu-dai (環月臺) — 1672
Dedicated to the wife of the founding lord Tsugaru Tamenobu, this hall was originally built in 1628 but was reconstructed in 1672. Despite being the earliest in terms of original dedication, its current structure dates from the later reconstruction. Like most of the group, the ceiling bears a painted dragon.
Ryoun-dai (凌雲臺) — 1753
The most recent of the five, this mausoleum was built for the sixth lord, Tsugaru Nobuyasu. Constructed during the mid-Edo period, it shows subtle stylistic differences from the earlier halls, offering visitors a visual record of how architectural tastes evolved over more than a century.
Why Were They Designated as Important Cultural Properties?
The Tsugaru Clan Mausolea were designated as Important Cultural Properties of Japan on January 22, 1986, with their front gates and fences (tamagaki) added to the designation in 1993. Several factors contributed to their significance:
- They represent a complete set of datable feudal-era mausolea spanning from the early to mid-Edo period (1631–1753), making them invaluable for studying the evolution of funerary architecture.
- The five halls share a consistent overall design yet exhibit distinct variations in decorative detail, reflecting the stylistic preferences of each era.
- The row of mausolea creates an outstanding landscape of full-scale funerary architecture rarely preserved in such completeness elsewhere in Japan.
- Unique features such as the Tokugawa hollyhock crest on Meikyo-dai and the celestial maiden ceiling painting in Hakuun-dai add historical and artistic interest.
Highlights and What to Look For
Visiting the Tsugaru Clan Mausolea is like stepping into a quiet, centuries-old memorial garden. The five halls stand in a dignified row behind the main hall of Choshoji Temple, each enclosed within its own fence and gate. The unfinished wood exteriors have aged gracefully, blending harmoniously with the surrounding ancient cedar trees.
Pay close attention to the family crests on each building: four bear the Tsugaru peony, while Meikyo-dai alone displays the Tokugawa hollyhock — a silent testament to the political marriage that connected the Tsugaru clan to the ruling Tokugawa shogunate. If you are fortunate enough to view the interiors during a guided tour, the vivid ceiling paintings — dragons in four halls and a celestial maiden in one — are extraordinary examples of Edo-period artistry preserved in remarkably good condition.
The broader temple grounds of Choshoji are equally impressive. The towering Sanmon (main gate), standing over 16 meters tall and dating to 1629, is itself an Important Cultural Property. The main hall, kitchen quarters (kuri), Portrait Hall (Mieido), and a Kamakura-period bronze bell are also designated cultural properties, making Choshoji one of the most culturally dense temple complexes in northern Japan.
Surrounding Attractions
Choshoji Temple sits at the far end of Zenringai, a unique avenue of 33 Soto Zen temples that is itself designated as a National Historic Site. A leisurely walk through this atmospheric district, lined with ancient cedars, is a highlight of any Hirosaki visit. Nearby attractions include:
- Hirosaki Castle and Hirosaki Park — famous throughout Japan for its spectacular cherry blossoms in spring and vibrant autumn foliage. The castle keep is one of only twelve surviving original castle towers in the country.
- Saishoin Temple Five-Storied Pagoda — the northernmost five-storied pagoda on the main island of Honshu, also an Important Cultural Property, located south of the castle.
- Fujita Memorial Garden — a beautiful Japanese garden offering views of Mount Iwaki, with both Japanese and Western-style buildings.
- Tsugaru-han Neputa Village — a cultural complex where you can experience Hirosaki's famous Neputa Festival floats, Tsugaru shamisen music, and traditional crafts year-round.
- Mount Iwaki (Iwaki-san) — known as "Tsugaru Fuji" for its elegant shape, this volcanic peak offers hiking and scenic views.

Q＆A
- Can I see the interior of the mausolea?
- The mausolea are usually viewed from outside the enclosing fences. However, guided tours that include interior access are available through the Hirosaki Tourism and Convention Association. Advance reservation is required (at least 7 days ahead), with a minimum group size of 10 people. The guided tour costs 300 yen per person and lasts approximately 40 minutes.
- What is the best time of year to visit?
- The temple is open from late April through November (9:00 AM to 4:00 PM). Spring is ideal if you wish to combine your visit with cherry blossom viewing at nearby Hirosaki Park. Autumn offers beautiful foliage along the cedar-lined Zenringai avenue. The temple is closed to general visitors from December through March (group reservations only during winter).
- Is English-language information available on-site?
- On-site signage is primarily in Japanese, and the guided tour is conducted in Japanese. However, the Hirosaki Tourism and Convention Association can sometimes arrange English-speaking volunteer guides with advance notice. It is recommended to research the site beforehand or use a translation app during your visit.
- How do I get to Choshoji Temple?
- From JR Hirosaki Station, take the Konan Bus bound for Nishimeyamura or Soma Line and get off at the Shigemori-machi Choshoji Iriguchi stop (about 15 minutes). From there, walk west along the Zenringai avenue for about 5–10 minutes until you reach the temple at the far end. The seasonal Tamenobu-go loop bus also stops nearby. Rental bicycles are available in the city center and offer a pleasant way to explore.
- What is the difference between the Tsugaru-ke Tamaya and the Tsugaru Tamenobu Tamaya?
- The Tsugaru-ke Tamaya (Tsugaru Clan Mausolea) at Choshoji Temple consists of five halls dedicated to successive lords and consorts. The Tsugaru Tamenobu Tamaya is a separate, more ornate mausoleum dedicated to the founding lord Tamenobu, located at nearby Kakushu-ji Temple. Both are Important Cultural Properties, but they are at different locations.
