Your broker's tax report may be wrong for Japan

US brokers use FIFO (First-In, First-Out). Japan requires Moving Average.

Example: You trade Apple stock
Buy 10 shares @ $150
Buy 10 shares @ $200
Sell 5 shares @ $220
🇺🇸 Your 1099-B (FIFO)
Cost: $150 × 5 = $750
Proceeds: $1,100
Gain: $350
What your broker reports
🇯🇵 Japan NTA (Moving Avg)
Avg: ($150 + $200) ÷ 2 = $175
Cost: $175 × 5 = $875
Proceeds: $1,100
Gain: $225
