Mizuho Securities’ Japanese brokerage pricing depends on the service course and the channel used to place an order. Direct Course emphasizes online and telephone dealing; 3 Support adds a consultant and branch-based services. The same Japanese share can therefore incur a different commission without any difference in the security itself.[2][3]

Domestic stock commissions
Sections ↑The following online cash-share rates include tax. Actual billing calculates tax from a rounded pretax amount, so a simple multiplication can differ slightly. For sales below the relevant minimum commission, the published schedule substitutes 99% of sale proceeds. Credit-trading charges and foreign securities have separate schedules.[4][3]
