In order to produce a neutron-rich Lambda hypernucleus for the first time, we carried out an experiment by utilizing the (pi(-), K+) double charge-exchange reaction on a B-10 target. We observed the production of a Li-10(Lambda) hypernucleus. The cross section for the Lambda bound region was found to be 11.3 +/- 1.9 nb/sr with the 1.2 GeV/c incident momentum, which is compared with the B-10(Lambda) hypernucleus production cross section, 7.8 +/- 0.3 mub/sr, in the (pi(+), K+) reaction with a 1.05 GeV/c incident momentum beam.
