The question "日本語できる？" means "Can you do Japanese?" or "Do you speak Japanese?" As a large language model, I am capable of understanding and generating Japanese text. I can read, write, translate, and converse in Japanese, so the answer is yes. While my Japanese ability may not be perfect compared to a native speaker, I have substantial proficiency in the language and can handle a wide range of tasks in Japanese. Therefore, "Yes" is the appropriate and honest answer.
