An observation of extensive air showers was performed at Mt. Norikura (2840 m above sea level and 25 deg N geomagnetic latitude) with two multiplate cloud chambers, 90 sparsely distributed G-M counters and two sets of counter horoscopes. In this experiment, the structure of the air shower in the neighborhood of the shower axis was investigated. Integral alze spectrum was obtained as 6.1 x 10^-9(N/10⁵)^-1/5 cm^-2 sec^-1 s r^-1 for the showers with a total number of particles 1.5 x 10⁵ -- 5.5 x 10⁵ and for large size showers the exponent of the spectrum increases with shower size reaching about --1.9 at N = 10⁶.
