Siblings applying for student visas. Has anyone done this?

My two brothers and I are considering applying to the same language school in Japan around the same time. Im aware that we’d each need to apply for our own student visa separately and meet our own financial requirements, but I’m wondering how realistic this is in practice if all three of us are attending the same school. I’ll be 25, my brother 24, and our older brother 29. Has anyone here done something similar or know if this raises extra scrutiny during the visa process? We’d be living together, if possible.
