Field notes
The visible workflow is unusually explicit for an insurance platform: create a versioned risk object, attach a structure, and run a backtest through four shown curl calls. Its demonstration uses the Kanto earthquake feed over 1986–2025 and reports six paid seasons, a JPY 1 billion largest annual payout, and a 4.375% annual burning cost. The page distinguishes descriptive history from forecasting and identifies the exact backtest run.
