No, in Hawaii a landlord generally can’t evict a tenant “for no reason” during the term of a fixed lease; they must have legal cause (like nonpayment of rent, lease violations, illegal or harmful activity) and follow the required notice and court process.
If there is no written lease agreement or a written lease has expired and isn’t renewed, the landlord doesn’t need to give a separate reason to end the tenancy. For periodic tenancies (e.g., month-to-month), the landlord must give the required written notice (typically at least 45 days for month-to-month) before pursuing eviction if the tenant doesn’t move out.
