When working in a Japanese company, it is important to be aware of the following points: 1. Respect for hierarchy and seniority is highly valued in Japanese culture, so always show deference to your superiors. 2. Punctuality is crucial, so be sure to arrive on time for meetings and work tasks. 3. Business communication in Japan tends to be more indirect, so pay attention to subtle cues and read between the lines. 4. Building strong relationships with your colleagues and clients is key, so invest time in getting to know them on a personal level. 5. Finally, be mindful of cultural differences and be open to adapting your communication and work style to fit in with your Japanese counterparts.
