The 3-stepped bracket complexes *mitesaki tokyō 三手先斗きょう, frog-leg struts *kaerumata 蟇股, centered between the bracket complexes, double eaves *futanoki 二軒, and closely spaced rafters *shigedaruki 繁垂木, all reflect theｗayō style *wayō 和様, although the gable pediments have double rainbow beams, nijū kōryō 二重虹梁, separated by bottle struts *taiheizuka 大瓶束, instead of frog-leg struts, which is a deviation from the wayō style. The roofing is copper sheeting set over wooden planks with semi-circular battens, kawarabō 瓦棒, covering the seams, producing a simulated tile roof *hongawarabuki 本瓦葺. The worship area, 11 × 4 bay deep, has a floor paved with stones set diagonally. Between the sanctuary and the worship area, all eleven bays have hinged double doors opening toward the worship area.

Two more altars, both facing the outer line of moya pillars, are at the extreme right and extreme left. Each bay is enclosed by doors that are divided horizontally into two latticed and boarded panels *shitomido 蔀戸. Gently inclined steps, 3-bays wide, form the approach to the front entrance. Shallow railed verandas border the worship area with narrow steps on each side, front and rear. There is no veranda surrounding the sanctuary. This hall is located at the center of the Enryakuji compound and is said to have been built within the area of the lost east pagoda. The temple was established by Saichō 最澄 (767-822) who re-introduced the Tendai 天台 sect of Buddhism into Japan. The temple was first called Hieizanji 比叡山寺 and later changed to Ichijōshikan'in 一乗師潅院 and finally to its present name. Saichō himself was given several titles, one of which was Konpon Daishi 根本大師, from which the hall derives the name konpon.
