I have done international-domestic transfer (AA-JL) at HND in two hours, but I will not recommend it. I just did it once and have never done it since. Luckily everything went smoothly but I was taking a chance on that. I will say three hours to be on the safe side.
Your flight is JL 1 arriving HND at 3:00 p.m. My recommendation for same day transfer to OKA will be:
6J (Solaseed Air) 25: HND 6:10 p.m., OKA 8:55 p.m.
JL 925: HND 7:55 p.m., OKA 10:25 p.m.
NH 479: HND 8:00 p.m., OKA, 10:30 p.m.
JL has 3:55 p.m. and 4:55 p.m. departure to OKA. NH has 3:30 p.m., 4:25 p.m., and 4:55 p.m. to OKA. I will not recommend any of these if your international arrival is at 3:00 p.m.
