    • Summary.

    • CTA.

    • Introduction: Set the scene. “You buy a house, but you pay tax every year.” This is a recurring cost.

    • H2 (1): Use the formula: $\text{Tax} = \text{Assessed Value} \times 1.4%$. Mention that the assessed value is usually around 70% of market value. Data point: For a 40 million yen house, tax might be roughly 100k-150k/year.

    • H2 (2): Focus on the “Residential Land Special Provision.” Small residential land ($<200m^2$) gets $1/6$ reduction. This is massive. So what? If you build a house on land that was previously vacant, your tax will jump significantly after the grace period.

    • H2 (3):

      1. Energy efficiency: 2026 era focuses on ZEH/ZEH+. Mention tax breaks for eco-friendly renovations.
      2. Business vs. Residential: Don’t misclassify.
      3. Small-scale ownership: Avoid holding onto “dead land.”
    • H2 (4): 2026 perspective. Inflation might lead to higher assessed values. Tax assessment cycles (3 years).

    • Tone Check: Ensure variety in sentence endings (~だ、~といえます、~でしょう、~が必要です).

    • Self-Correction during writing: Ensure I don’t sound like a tax accountant (avoiding “I guarantee this”), but rather a researcher providing information. Use phrases like “一般的に” (generally) or “制度によりますが” (depends on the system).

    • 1500-2000 characters? Let’s expand on the calculation and the specific reduction years.

    • H2 count? 4-5.

    • Numbers? Included (1.4%, 1/6, 3 years, etc.).

    • “So what?” Included.

    • CTA included.

    • H1: 固定資産税の仕組みと節税テクニック2026年版|知らないと年間数万円の差が出る?

    • Intro: Living in Japan means paying tax.

    • CTA.

(Self-Correction on “2026 Edition”): Since 2026 is in the future/near-term, I should frame it as looking ahead to the next valuation cycle or the impact of inflation/energy standards which are becoming stricter.
