Mayekawa and his office have completed various projects throughout Japan from north to south. Many of those realized and existing architecture are public cultural facilities such as museums, theaters and halls; Tenjinyama Cultural Plaza, the site of this project is one of them. Mayeawa's contribution in Japan is virtually ubiquitous as regional characteristics and ethnicity rarely can be seen from his works.

Relationship with green area and open spaces is one of the essential and the most considered factor for the public cultural facilities designed by Mayekawa. Majority of his works have a green area at least, or situate next to parks, and some of them have cultural monuments as neighbor. In that case, his work emphasizes the royalty of the monuments, and facilitates opportunity for local people get along with.

Tenjinyama Cultural Plaza was originally built as a library and worked from 1962 to 2004, and the current exhibition room had been designated as a reading lounge having the glass facade with brise soleil on the north side. As social demands rapidly growing nowadays, such change of spatial use, renovation and conversion are inevitable among those aging modernist architecture - Mayekawa's works are not exception.

Tenjinyama Cultural Plaza has more than two entrances meaning it offers complex yet multi-sensory experience for visitor. For example one uses the outside stair to the second floor, then enter the building and faces the 2 story-height opening in the atrium leaving the west-faced glass entrance behind. It is not difficult to imagine that the sequence of natural light in the space would be dramatic.

Color combinations taking from each of the buildings, the colors have used to composite the interior spaces, by painting or filled with colored materials and tiles. Each of the combinations consists three parts of interior spaces; ceiling, wall and floor, to compare the usage of colors and identify the common color scheme of Mayekawa's works. (All the registered information is based upon the research in 2018-2019)

Analyzing the existing color combinations. Blue is the most dominant color for ceiling. Wall color can be act as associated color, and covers full range of brightness and hues including pale colors. Accent color tends to be more vibrant. The analysis proved that Mayekawa had played with extensive range of colors interior, contrasting the monotonous exterior of concrete and ceramic tiles.

The structure of the building has not been changed. The north facade of the current exhibition room is completely covered by the brise soleil, from floor to ceiling, for its original purpose of activity, reading. There would had been enough amount of natural light introduced to the space, but less contact with outside - the architecture behaves as a huge concrete mass in the town seeing from outside.

The use of curtains in modernism architecture is profound. particularly in the space where is giving extra comfort: such as living room in private housings including architect's own house. Although the modernist architecture is a synonym to the functional and geometrical appearance with minimum decor, the curtain is seems to be demanded and somewhat its drape adds rhythm and order on facade.
