    We propose a fast method of calculating the p-part of the class numbers in certain non-cyclotomic ℤp-extensions of an imaginary quadratic field using elliptic units constructed by Siegel functions. We carried out practical calculations for p=3 and determined λ-invariants of such ℤ3-extensions which were not known in our previous paper.
