Sawatari (SWT) — Completing the Stewardship Cycle

Structural realities, risk thresholds, and respectful exit pathways

This page exists for planning truth. It is not a “panic page”, and it is not intended to pressure anyone. It is a calm reference for the day when the family needs clarity.

Notice: This is a conceptual stewardship reference, not legal or engineering advice. For decisions affecting safety, repair, or demolition, consult qualified professionals.

1) The core reality (why this page exists)

SWT has a baseline annual carrying cost (approx. ¥650,000/year) just to keep the property stable in its current condition while unoccupied (tax, utilities, maintenance, connectivity, security, and repairs).

However, once a building shows visible signs of termite activity (シロアリ), the planning frame changes: the structure may already be in a state of decline even if it “looks fine” from the outside.

2) What was observed (field notes)

  • Exterior rear wall: frequent termite holes visible across panels and posts
  • Density indicator: approximately one small hole every ~20cm (suggests established activity)
  • Underfloor assumption: joists / bearers / sill plates may be affected to varying degrees

Stewardship translation:

This is no longer only a “maintenance budget” question. It becomes a threshold decision: whether to (A) treat + repair, (B) hold safely for a period, or (C) plan a dignified ending and reset.

3) Why termites change the economics

The baseline annual cost (¥650,000/year) is designed to prevent gradual decline in a stable structure. Termite activity means the structure may already be losing value faster than routine maintenance can recover.

  • Maintenance spending slows decline, but does not restore lost strength.
  • Partial repairs often reveal deeper damage (cost escalation risk).
  • Delay typically increases total cost (repair or demolition) and reduces safe options.

4) Cost bands (planning order-of-magnitude)

These figures are planning bands only. Real quotes vary by access, scope, materials, and damage depth.

Scenario What it does Planning Band
1) Treatment only Stops active termites, but does not restore structural strength ¥150k – ¥300k
2) Treatment + partial structural repair Replace/strengthen compromised members (scope expands once opened) ¥1.5M – ¥4M+
3) Major remediation / rebuild-level repair Full-scale corrective work; often competes with demo + rebuild costs ¥5M – ¥10M+

5) Decision thresholds (simple, calm)

Rule 1: If the building cannot be made structurally safe without multi-million yen spend, the family should consider whether the “main house” is still a rational asset.

Rule 2: If “light maintenance” is chosen, accept that this is holding time, not preservation. It should have an agreed review date (e.g., 12–24 months).

Rule 3: If SWT cannot reliably generate ≥ ¥650,000 net per year, and capital repairs are required, the property is being subsidized by the future.

6) Respectful pathways (no shame, no drama)

These are common stewardship pathways when a building reaches end-of-life conditions:

  • Path A — Stabilise & wait: minimum safety actions + monitor, with a fixed review date.
  • Path B — Treat & repair: commit to full inspection, treatment, and scoped repairs (budget clarity first).
  • Path C — Dignified ending: secure valuables, document the home, then plan controlled demolition and site reset.

7) Practical next steps (when the time is right)

  1. Professional inspection: termite + structural (underfloor and key load points)
  2. Define scope: “treatment only” vs “treatment + repairs” vs “end-of-life plan”
  3. Get 2–3 quotes for the chosen scope
  4. Set a family review date (avoid indefinite drift)

Closing note: Completing a stewardship cycle is not failure. It is a form of respect — for the place, for the family, and for the next generation’s freedom.
