I don't know much about transracialism at all, but it makes sense to me if you look at it as a cultural identification kind of thing. Both my brother and I were born in and grew up in the states, but I identify more with American culture while he identities more with the culture our parents are from, so culture at least is a mental identity thing rather than a physical reality.

If it's purely a racial/ethnic kind of thing that's about your genetic heritage, I agree it doesn't make sense to apply the same concept. It's like the distinction between sex and gender I mentioned above, trans people identify as a specific gender regardless of their sex, and I think people can identify with a specific culture regardless of their race/ethnicity. To better complete the analogy, I could definitely imagine a white person growing up in Japan their whole life and feeling a general unease about the mismatch between their cultural identity (Japanese) and their race/ethnicity (white), and in cases where that unease is severe enough, potentially being willing to go through surgery to better reflect their identity. Dysphoria over racial/cultural mismatch (if it even exists, idk) seems much less common than gender dysphoria, but I don't see why you wouldn't apply the same logic to both.
