This paper is a part of the researches to characterize and identify the architectural theory of Jun Itami (1937-2011) through all the currently available articles written by him. The keywords of the subjects were sorted out as a number of items and examined from the viewpoint of hierarchy of composition of the meaning by extracting important sentence.

《Nature》consists of the third level of three items of [Climate], [Natural Environment], and ［Garden］ [Natural Environment] consists of the 4th level of three items of 〈Mountain〉, 〈Rock〉, and 〈Light〉. ［Garden］, consists of the 4th level of two items of 〈Garden of private house〉 and 〈Secret garden〉.《Human》have not the third level items. 《Village》 consists of the third level of two items of [Relationship with nature], and [To contemporary city]. [Relationship with nature] consists of the 4th level of two items of 〈Integration with nature〉 and 〈Response to mountains〉. 《Architecture》 consists of the third level of three items of ［Private house］and ［Jongmyo Shrine］. ［Private house］ consists of the 4th level of eight items of 〈Coexistence with nature〉, 〈Reflection of life〉, 〈Fence〉, 〈Korean floor heater〉, 〈Connection inside and outside〉, 〈Eye movement〉, and 〈To contemporary house〉.［Jongmyo Shrine］consists of the 4th level of seven items of 〈Relationship with water〉, 〈Roof〉, 〈Eye movement〉, 〈Base〉, 〈Nothing〉, 〈Margin〉, and〈"Theater space"〉.
First, Itami spoke of 《Human spirit》 respect for 《Nature》 based on confucianism, and mentioned the 《Village》 where such people gathered and lived. There, we can see 〈Integration with nature〉 and 〈Response to mountains〉, and the 《Human spirit》was also observed there.
Next, he most discouraged discourse was about 《Architecture》 that was at the center of thought about 【Korea】. He observed ［Private house］ and explained the famous Korean traditional architecture, ［Jongmyo Shrine］ and 〈Secret garden〉.
There, we analyzed words such as 〈Nothing〉, 〈Margin〉, and 〈Theater space〉 that were used in his architectural works. He got what he could use for his own design activities from 【Korea】, and also considered future Japanese architecture by referring to these theories.
