A Stone Basin in the South-East Corner of a 1928 Garden
The Tsukiyama Residence Water Lily Pond (築山家住宅水蓮池, Tsukiyama-ke Jūtaku Suirenike) is a stone garden pond built in 1928 at Kinuta in Setagaya City, Tokyo, and entered on Japan's national register of Tangible Cultural Properties on 2 October 2007. It lies in the south-eastern part of a private plot and is one of four elements of the same house that carry the registration.
The pond is small. It runs north to south, 1.2 metres across and 4.1 metres long, and the register gives its area as 6.4 square metres. Those two figures look as though they disagree, because 1.2 multiplied by 4.1 comes to about 4.9. The gap is the edging. A band of stone 0.13 metres wide runs around the basin, and once that band is added on all four sides the footprint grows to roughly 1.46 by 4.36 metres, which multiplies out at 6.4.
At each of the four corners sits a squared block measuring 0.24 by 0.29 metres. These blocks are wider than the edging band they interrupt, so they push outward at the angles. Seen from above the outline stops being a plain rectangle and reads as a cross, and the register describes the shape in exactly those terms.
All of it is Ōya stone (大谷石), the pumiceous tuff quarried around Ōya in the north-west of Utsunomiya, Tochigi Prefecture. Soft enough to cut with hand tools, light to carry, resistant to fire and to damp, it became the default material for garden walls, gate posts, paving and storehouses across the Tokyo suburbs during the 1920s and 1930s.
The position was chosen with some care. The basin sits directly south of the room at the eastern end of the main house's south elevation, a room the survey record calls the rōjinshitsu (老人室), set aside for an elderly member of the household. The arrangement puts water in the sight line of the one room least likely to stand empty through the day. The register documents the location and nothing more, so the reasoning behind it is inference rather than record.
Two Tiers of Protection, and Why a Small Pond Qualifies
Japan protects historic buildings at two levels, and the distinction matters for reading anything about this property. Designation (指定) as an Important Cultural Property (重要文化財) or a National Treasure (国宝) applies to a small, tightly selected group and brings permit requirements along with substantial public support. Registration (登録) is the lighter tier, created by an amendment to the Law for the Protection of Cultural Properties that took effect on 1 October 1996. It was built to catch the large volume of modern buildings vanishing before anyone had the chance to assess them. Owners notify the authorities ahead of major alteration and receive guidance in return, rather than being locked into a permit system. The Tsukiyama pond belongs to this second tier.
Four parts of the property were registered on the same day: the main house (register number 13-0217), the gate (13-0218), the stone wall (13-0219) and the pond (13-0220). Public notice followed on 22 October 2007, in the fifty-sixth round of registrations.
The grounds are not identical across the four, and the difference repays attention. The main house was taken in as a model of design (造形の規範となっているもの). The gate, the wall and the pond came in under a separate criterion, contribution to the historic landscape of the country (国土の歴史的景観に寄与しているもの). The pond, on that reading, was valued for completing a coherent piece of 1920s domestic planning rather than for artistry of its own.
One line in the register does single the pond out. It calls a basin of this kind a garden fitting frequently found in houses designed by Yamada Jun. The pond is therefore documented evidence of an architect's working habit, not a guess drawn from resemblance.
Yamada Jun (山田醇, 1884-1969) was born at Kanasaki in Chichibu, Saitama Prefecture, and graduated in architecture from Tokyo Imperial University in 1912 alongside Watanabe Jin and Nishimura Yoshitoki. He worked at the Tatsuno Kasai office, contributed to the Dai-ichi Sōgokan building, and went independent in Kobe in November 1917. He moved his practice to Tokyo in 1922 and completed his own house and office there in 1924, the year after the Great Kantō Earthquake. Houses were his subject for the rest of his career. After his son fell ill he turned to research on what he called health housing, publishing on the theme from the 1930s through to 1960. His book Ie o Tateru Hito no Tame ni (For People Building a House) appeared in 1928, the same year the Tsukiyama house was completed.
The main house shows his manner plainly: two timber storeys under a tiled roof with a footprint of 158 square metres, a central-corridor plan, a wide veranda and terrace across the south face, a steeply pitched gable roof carrying a large raised dormer, and half-timbered treatment on the gable ends.
Standing Outside: What the Street Gives You
The house is lived in. There is no public opening, no interior access, no garden access and no visitor information, because there is no visitor programme. Registration in Japan places no obligation on an owner to admit anyone, and a great many registered houses are simply somebody's home.
The pond compounds the problem. From the lane it sits behind the house, in the south-east of the garden, so even a determined look over the boundary will not reach it. Photographs are scarce for the same reason, and the Agency for Cultural Affairs database remains the most dependable place to see one.
What the street does hand over is the rest of the group. The gate stands on the northern boundary facing the road, and the Ōya stone wall runs 59 metres around the north and east edges of the plot, holding the ground roughly 0.7 metres above road level. Both are registered in their own right and both are cut from the same stone as the pond. To understand the pond without seeing it, the wall is the closest available reading of its surface, its colour and the way its courses sit.
Getting there is easy enough. Soshigaya-Ōkura Station on the Odakyu Odawara Line is about ten minutes away on foot, and Seijō-gakuen-mae on the same line makes a slightly longer walk from the west. The last stretch runs through narrow residential lanes, some without pavement. Keep to the road, keep the camera on the street-facing stonework rather than the garden or the windows, and leave the doorbell alone. Kinuta Park and the Setagaya Art Museum sit about two kilometres to the south-east for anyone who wants an afternoon somewhere they are actually invited.
A note on the name. The register writes the pond 水蓮池, using 水蓮 for water lily where modern Japanese normally writes 睡蓮. The reading, suiren, is unchanged. Those characters record what the basin was meant to hold; the register's own description covers the stonework alone and says nothing about planting.

Q&A
- Can I visit the Tsukiyama Residence Water Lily Pond?
- No. It stands in the private garden of an occupied house at Kinuta in Setagaya, and there is no public opening or interior access. The pond lies in the south-eastern part of the garden, behind the main house as seen from the lane, so it cannot be viewed from the public road either.
- Where is the Tsukiyama Residence Water Lily Pond, and which station is nearest?
- The address is 8-18-12 Kinuta, Setagaya City, Tokyo. Soshigaya-Ōkura Station on the Odakyu Odawara Line is the nearest stop, roughly ten minutes on foot, with Seijō-gakuen-mae a longer walk from the west. The final approach runs through narrow residential lanes, so allow a little extra time.
- When was the Tsukiyama Residence Water Lily Pond built and when was it registered?
- It was built in 1928 (Shōwa 3), the year after the Odakyu Odawara Line opened and brought this stretch of Setagaya within commuting reach of Shinjuku. Registration came on 2 October 2007, with public notice on 22 October 2007, in the fifty-sixth round. Its register number is 13-0220.
- Who designed the Tsukiyama Residence Water Lily Pond?
- The house was designed by Yamada Jun (山田醇, 1884-1969), a specialist in private houses who trained at Tokyo Imperial University and set up on his own in Kobe in 1917. The register names no separate garden designer, but it records that ponds of this type appear regularly in houses he designed.
- Is the Tsukiyama Residence Water Lily Pond a National Treasure or an Important Cultural Property?
- Neither. It is a Registered Tangible Cultural Property (登録有形文化財), the lighter tier of protection introduced in 1996, which works through notification and guidance rather than permits. National Treasures and Important Cultural Properties belong to a separate and more tightly regulated category, and the two should not be confused.
