It's not opensource yet, but the newest Deepseek's V3 (0324) is absolutely killing Japanese to English from my testing. Of course, if it's like the previous version, it's a near 700b model so unless you have enough money to spend on a new car you won't ever be able to use it unless you pay the API cost from a service like Openrouter (It's actually free to use the service right now if you want to give it a test)I wonder which are the best open-source models
