Marukuni has a tiered fee structure for stock brokerage commissions, which can become quite expensive, especially for smaller trades. For instance, if the contract price is below ¥4,000, the fee is 55% of the contract price, which is steep. As the contract size increases, the fee becomes a percentage of the contract price, ranging from 1.26% to 0.33% for trades over ¥50 million. Personally, I find the tiered structure complicated and costly for smaller trades, making it less appealing for frequent or small investors.
