Step-by-Step Guide to Using the Calculator

1. Enter the House Price (JPY):
   Input the total cost of the property you want to purchase. For example, a typical suburban home might cost around ¥30,000,000.
2. Enter the Down Payment (JPY):
   Japanese banks usually require at least 10–20% as a down payment. For a ¥30,000,000 home, this might be ¥6,000,000.
3. Enter the Annual Interest Rate (%):
   In Japan, housing loans often have very low rates, sometimes between 0.5% and 2%. Enter your expected rate (e.g., 1.5%).
4. Enter the Loan Term (Years):
   Standard terms in Japan are 20–35 years. Longer terms mean lower monthly payments but more total interest paid.
5. Click "Calculate":
   The calculator will instantly display:
   • Total loan amount (house price minus down payment)
   • Monthly payment estimate
   • Total repayment over the loan period
   • Total interest paid
