Drawing from my experience as an independent forex trader who has worked with a range of platforms, my interactions with MUFG—specifically through their au Kabucom Securities—have mostly been positive when it comes to the reliability of their trading infrastructure. Their self-developed platform, along with the au Kabucom FX app, has generally provided stable access, and being backed by a well-established financial institution regulated by Japan’s FSA does provide a solid sense of security for me. In my time trading with them, I have not encountered any major technical outages or execution delays that significantly impacted my trading decisions, which is crucial for anyone trading in fast-moving markets like forex. However, I've noticed some limitations that could be important for international traders or those who are not proficient in Japanese. The platform and customer support services are predominantly conducted in Japanese, which can create a communication barrier if you’re not fluent in the language. From my point of view, reaching out for assistance via live chat or by phone yielded competent and courteous responses, but only within the language the service offers. This could certainly be a drawback if English or another language is your preference. Regarding customer service, my queries were handled in a timely manner, but the lack of multilingual support and limited global outreach suggests MUFG is not currently focused on serving a broader, international clientele. This is something to be carefully considered—especially if you expect frequent, in-depth support in a language other than Japanese. For my purposes, MUFG met my expectations, but for traders requiring broader linguistic support or international-facing services, this limitation could be significant. Ultimately, for me, the reliability has been sound, but the language barrier in customer service is a notable factor to weigh before committing.
