 Lángara began his football career playing for local teams, Bildur Guchi, Esperanza de San Sebastián, Siempre Adelante de Pasajes and Andoain in his native Basque country, eventually signing for then third division team Tolosa CF.When he turned 18, his goalscoring abilities were recognized by second division team Real Oviedo, a club with whom he would remain for 6 years, until the Spanish Civil War broke out in 1936.At Oviedo he was the figurehead of the celebrated "Delantera Eléctrica", a forward line of lightning quick youthful talent that steam-rolled teams with high tempo highly skilled play; but for the onset of war the team would have surely improved upon the two-third places in the seasons that preceded the war.
