Rinzai-ji Began as the Imagawa Clan’s Family Temple
Rinzai-ji in Aoi Ward, Shizuoka City, is the family temple of the Imagawa clan, who ruled Suruga, and a Zen temple where the histories of Imagawa Yoshimoto and Tokugawa Ieyasu intersect.
Preserved as a training monastery, the grounds contain the main hall, garden, Imagawa family graves, and other cultural traces extending from the Sengoku period into the early modern era.
A Zen Temple with Zentoku-in as Its Predecessor
Rinzai-ji is said to have originated as Zentoku-in, founded by Imagawa Ujichika.
As a place where Imagawa politics and Zen culture came together, it provides a starting point for exploring the history of Sumpu.
Known as the Family Temple of Imagawa Ujiteru
Rinzai-ji was founded by Imagawa Ujichika and is known as the family temple of Ujiteru, Yoshimoto’s elder brother and the 8th head of the Imagawa clan.
The temple’s name derives from Ujiteru’s posthumous Buddhist name, and graves and statues associated with Ujiteru and Yoshimoto have been preserved on the grounds.
Temple Buildings Repeatedly Damaged by War and Rebuilt
Rinzai-ji suffered fire damage in conflicts involving Takeda Shingen and Tokugawa Ieyasu, and its temple buildings were rebuilt each time.
Rather than viewing the buildings as unchanged since their original construction, it is important to see them as layers of history shaped by destruction and recovery.
The process by which the Imagawa family temple came under Tokugawa patronage shows that the temple’s role continued even as control of Sumpu changed hands.
| Person or Period | Connection to Rinzai-ji | Perspective |
|---|---|---|
| Imagawa Ujichika | Founded its predecessor | The Imagawa clan and Zen |
| Imagawa Ujiteru | Origin of the temple’s name | Role as a family temple |
| Imagawa Yoshimoto | Clan leader supported by Sessai | Faith of a Sengoku daimyo |
| Tokugawa Ieyasu | Study and reconstruction | From the Imagawa clan to the Tokugawa clan |

See Hōjō-Style Architecture in the Important Cultural Property Main Hall
The main hall of Rinzai-ji is a nationally designated Important Cultural Property, notable for its large hōjō-style plan and Kyoto-influenced design.
Looking beyond the exterior and focusing on the spatial layout that supported life and ceremonies at this Zen temple makes the building’s value easier to understand.
A Large Main Hall from the Early 17th Century
The main hall is believed to date from the early Edo period.
It was designated a national Important Cultural Property in 1983.
Measuring 22.7m across the front and 16.8m from front to back, it features a broad hōjō-style floor plan facing the front.
Following the sweep of the eaves and the continuous spacing between the pillars reveals the structural framework supporting the large roof.
The entrance attached to the front left is also included in the designation as an associated structure, offering a clue to the ceremonial route into the main hall.
Irimoya Roof with Wooden Shingles
The single-story main hall has an irimoya hip-and-gable roof covered with thin overlapping wooden shingles known as kokera-buki.
Although parts of the roof and interior were altered in later periods, the structural frame retains much of its original form.
| Architectural Element | Feature | What to Observe |
|---|---|---|
| Floor plan | Hōjō style | Wide pillar spacing |
| Roof | Irimoya style | Shape of the ridge and eaves |
| Roofing | Kokera-buki wooden shingles | Overlapping boards |
| Associated designation | 1 entrance building | Connection to the main hall |

Discover Sumpu’s Zen Culture in the Scenic Garden
Rinzai-ji Garden, extending north of the main hall, is a nationally designated Place of Scenic Beauty distinguished by its use of elevation changes and flowing water.
Rather than seeing the garden simply as a view, consider it as a unified space of architecture, slopes, ponds, and plantings to appreciate its depth.
A South-Facing Garden Backed by a Slope
The garden uses the sloping ground north of the main hall as its backdrop and opens toward the south.
Instead of relying only on level ground, it incorporates the natural slope to create the three-dimensional feel of a mountain temple.
2 Ponds Connected by a Change in Elevation
Fresh water is directed into a pond on higher ground to the east, then flows down into a lower pond to the west.
Following the view from the water’s entrance to the pond, the drop, and the next pond reveals how a landscape recalling a ravine was composed within the limited garden.
Looking in sequence from the main hall toward the back of the garden also shows how the foreground pond and distant slope continue into one another, creating a sense of space larger than the actual grounds.
The Garden’s Value as a Designated Place of Scenic Beauty
Rinzai-ji Garden was designated a national Place of Scenic Beauty in 1936.
Its combination of pines, cycads, satsuki azaleas, other plantings, and exposed rock forms a cultural landscape preserved together with the temple’s history.
| Garden Element | Location | Effect |
|---|---|---|
| Slope | North of the main hall | Natural backdrop |
| Upper pond | High ground to the east | Starting point of the fresh water |
| Lower pond | Lower ground to the west | Expression of elevation change |
| Rocks and plantings | Around the ponds | Mountain-and-water scenery |

Trace the Studies of Taigen Sessai and Takechiyo
Rinzai-ji links the Zen monk Taigen Sessai, who supported Imagawa Yoshimoto, with the young Tokugawa Ieyasu, then known as Takechiyo.
The relationship between the 2 shows that the temple supported not only prayer but also education and politics.
Taigen Sessai, Adviser to Imagawa Yoshimoto
Taigen Sessai served as abbot of Rinzai-ji and, as Imagawa Yoshimoto’s teacher, was also involved in politics and diplomacy.
His story conveys how Zen monks in the Sengoku period provided spiritual support to daimyo and also influenced the governance of their domains.
The Temple Where Ieyasu Is Said to Have Studied
During his years as a hostage, Ieyasu is said to have received Sessai’s instruction at Rinzai-ji and devoted himself to learning.
Looking at the room associated with his writing practice and at the figures of these people makes it possible to imagine more concretely his boyhood in Sumpu, which shaped the future shogun.
The key to understanding this tradition is not to isolate Ieyasu, but to consider him together with Sessai, who provided education under the Imagawa clan, and the temple environment.

Explore Imagawa Memory Through the Graves and Temple Treasures
The grounds preserve the Imagawa family graves and statues connected with the clan, showing that Rinzai-ji remains a family temple carrying its memory forward.
Organizing the connections between the enshrined figures and the temple treasures, as well as the buildings and garden, makes the continuity of the history clearer.
Imagawa Family Graves Commemorating Ujiteru and Yoshimoto
The Imagawa family graves are a Shizuoka City-designated historic site and visibly express the temple’s role in mourning Ujiteru and Yoshimoto.
At the graves, visitors should quietly place their hands together, avoid entering the area around the stone monuments, and follow the temple’s guidance.
Connect the Statues of Yoshimoto, Sessai, and Others
Rinzai-ji preserves statues and objects representing Yoshimoto, Ujiteru, Sessai, and other associated figures.
Rather than merely memorizing their names, connect each person with the roles of foundation, education, politics, and reconstruction to understand their respective places in the story.
See the Main Hall, Garden, and Graves as One Story
The main hall conveys the history of reconstruction, the garden embodies Zen culture, and the graves preserve memorial rites for the Imagawa clan.
Instead of consuming these as 3 separate sights, see them as a continuous cultural heritage expressing the relationship between Sumpu’s rulers and the Zen temple.
Respect Viewing Conditions and Etiquette at This Training Temple
Rinzai-ji is a place of religious training, not a tourist facility where the inner grounds and cultural properties can be viewed freely at any time.
Even when visiting during limited public openings, visitors are expected to avoid disrupting religious practice and worship.
Check Public Opening Dates and Viewing Areas
Because opportunities for public access and the areas open to visitors are limited, check the schedule and conditions before your visit.
Do not rely solely on older travel articles or event information; give priority to notices at the entrance and instructions from staff.
Do not enter areas closed to the public. Even around the temple gate, stone steps, and other places visible from outside, observe from a position that does not obstruct passage or religious practice.
Prioritize Quiet Over Photography
Photography rules may vary by location and occasion, so confirm the areas where it is permitted.
Inside the halls, in the garden, and at the graves, avoid speaking loudly or occupying one spot for a long time, and keep the routes used by worshippers and monks clear.
Summary: Discover the Connection Between the Imagawa Clan and Ieyasu at Rinzai-ji
Rinzai-ji brings together several histories: a temple founded by Imagawa Ujichika and known as Ujiteru’s family temple, a place where Taigen Sessai and the young Tokugawa Ieyasu studied, and a Zen temple rebuilt after wartime fires.
Viewing the Important Cultural Property main hall, the scenic garden, and the Imagawa family graves in relation to one another gives a three-dimensional understanding of the culture extending from Sengoku-period Sumpu into the Tokugawa era.
Confirm public opening dates and viewing areas in advance, maintain the quiet conduct appropriate to a place of training and faith, and respect the work of passing these cultural properties on to future generations.
