Under the capacity density condition(CDC), it is known that the doublingcondition for harmonic measure holds on uniform domains, but not on Johndomains.As an intermediate domain between them, we introduce a semi-uniform domain.Under the CDC, we shall show that the harmonic measure of a John domain $D$satisfies the strong doubling condition if and only if $D$ is a semi-uniformdomain.
