It has been nearly five years since Manalili Villanueva Rosal was taken into custody on suspicion of murdering her lover in Matsudo, Chiba Prefecture.
"I would never be able to take the life of someone I love with all my heart," Rosal, 30, told the final session of her appeal hearing before the Tokyo High Court in June.
Presiding Judge Takeo Nakanishi is slated to rule on the case Wednesday.
