As an experienced trader who takes the cost structure of brokers seriously, I approached SANKO with a cautious mindset, especially given my priorities around transparency and avoiding unexpected fees. Based on all the information I was able to obtain, I found no publicly available details or disclosures about inactivity fees associated with SANKO. The lack of information presented by the firm stands out to me, particularly since fee schedules—especially those related to inactivity—can impact the overall profitability of my trading activities. SANKO is a Japanese broker with a legitimate retail forex license from the FSA, which generally suggests a certain standard of transparency and client protection. However, the firm does not provide an English website, limits its information to Japanese, and has not made its policies on inactivity fees or broader fee structures readily accessible. To me, this lack of disclosure is something I approach with extra caution. I always prefer clear and comprehensive fee information beforehand, as this allows me to accurately assess my ongoing costs and avoid any surprises. In my experience, when a broker does not clearly outline inactivity fees, it is wise to reach out directly to their customer support for clarification before opening an account or initiating any transactions. Without explicit confirmation in writing, I would not assume that inactivity fees do not exist, and I always recommend erring on the side of caution in such cases. For my own peace of mind and the integrity of my trading, I make sure to obtain any ambiguous information in writing.
