Raimu did not receive an Oscar nomination for portraying the Aimable, the baker in The Baker's Wife.
Raimu stands as one of the character's indirectly, though the actual wife of the baker is a rarely seen character given her disappearance relatively early on in the film. Raimu's performance here is a rather interesting one in that he is almost playing the part, initially, as what would be a side character within the film. Of course here he is the main character, or at the very least the core character within the film. Raimu though initially very much paints Aimable as the baker you are suppose to laugh at a little bit. This is not within playing too overtly, or without sympathy, but just granting his role this certain inherent joviality. Raimu exudes a natural energy of just a more simple man initially who is living out his life as he should be as this town baker, and with a cheerfulness towards his wife, even if she seems a touch disinterested in him. Raimu though colors the excitement with enough of this shade in his momentary reactions that suggest a certain underlying sensitivity towards this relationship, though he shows this seemingly to only encourage the character's overarching outgoing style that pushes the baker as the village's most happy man, though in a blissfully unaware sort to fashion.
That set up is pivotal within the film as Raimu makes the viewer like this baker well enough, even if he does encourage a little bit of laughing towards the man's own style though again in a rather low key fashion. Raimu's performance establishes the state of the man that he is going to essentially tear down through the rest of the film once it is discovered that his wife has run away. The switch is not immediate and this is where the power of Raimu's performance lies, even as the film's perspective frequently wavers from him towards the various townspeople reacting towards the situation. Raimu very much initially keeps that more positive energy in his work even as the baker reacts towards the news as well as some of the less encouraging words of the townspeople towards him. Raimu initially delivers these reactions though with enough of a humor in his surprise at becoming cuckold. He very much stays as that affable baker though Raimu even in his more joyful deliveries begins to exude more of that underlying desperation that alludes to a far less blissful state of ignorance than he partially suggests to be experiencing.
The story progresses actually closer to the larger scope of the fallout of the baker's wife departure than specifically the baker, given that he stops baking which effects the whole town. Although the film grants focuses to those various reactions, the through line though remains the baker's own connection to the loss, and his slowly fading mental state. Raimu's performance then brings upon this particularly potent emotional impact of the baker's predicament even as others somewhat glibly deal with it, and even the baker attempted to find some humor in the situation. When that fades Raimu's performance becomes a deeply moving exploration of the really depression within the baker. Raimu's work is particularly impactful in the way though is how he eschews that earlier joviality into this nearly grotesque state of the man who others still view as a joke, however the man is clearly deeply pained by the experienced. When some of the town's cruelty to persists the baker resorts to an attempted suicide. Raimu is honestly rather heartbreaking by so naturally realizing this point within the baker's horribly depressed state and showing to be the same kindly man we met in the opening. Of course this also makes his reprieve feel as natural as the baker decides to keep living in hopes of seeing his wife again, and the smallest glimpse of hope in Raimu's eyes as he speaks this desire poignantly refer to that greater joy from the opening scenes. Eventually the town does succeed in bringing back the wife, which leaves Raimu one final scene where the baker both must accept the return, but also deal with the idea of her betrayal of him. Raimu is fantastic in the scene though as it fully embodies the experience that has changed the baker. Raimu at no point simplifies it bringing out that singular joy though far more tempered in his rather blunt delivery of his more critical words towards his wife. Raimu though successfully portrays this moment as reconciliation, however as a reconciliation which doesn't bring things back to they were, but to a different point. Raimu in the end depicts a both the old and new baker, as he does now have a joyful spirit though a far more somber one that defines the man in his bittersweet end.
