Researchers have investigated the feasibility of training large language models to reason in Japanese, aiming to improve interpretability and user experience. They developed a Japanese-reasoning variant of the Qwen-3-Swallow-8B model, which was continually pre-trained from Qwen-3-8B using GRPO. While this approach allows for reasoning-language control, the model's performance on coding, math, and science benchmarks was only on par with strong English-reasoning baselines. Furthermore, the Japanese-reasoning model did not show improved performance on Japanese cultural benchmarks, indicating that reasoning in a non-English language does not automatically translate to better performance on culturally specific tasks.
