Example 1: 1 regular participant and 1 accompanying person

Total fee = 50,000 yen + 20,000 yen = 70,000 yen
Money that you transfer = 70,000 yen ? bank charge
Money that you pay to your bank = 70,000 yen

Example 2: 2 regular participants

Total fee = 50,000 yen + 50,000 yen = 100,000 yen
Money that you transfer = 100,000 yen ? bank charge
Money that you pay to your bank = 100,000 yen

Example 3: 1 regular participant and 1 student

Total fee = 50,000 yen + 20,000 yen = 70,000 yen
Money that you transfer = 70,000 yen ? bank charge
Money that you pay to your bank = 70,000 yen
