“Junin toiro (many men, many minds)”
(TOIRO)is The rent space which a country manages
In this facility that is named after “junin toiro”, I 
imagined the personality of each perosn as “colors”.  
When you walk across the white space, your shadow 
will be colored by the principle of “(*)additive 
mixture”.  This allows the space to become a place 
where people are able to see the “color” they primarily 
possess, but not seen usually.  Moreover, when 
people gather and the community becomes larger, a 
lot of shadows come together, gradually putting 
“colors” in a space where there was nothing.  And in 
each room, I expressed the layer of the “colors” by 
materials, which means placing the floor materials in 
layers and those layers of floors change colors, 
creating a various sized areas within the space.
*additive mixture (color shadow)
Additive mixture is a mixture that the brightness 
gained from the colors you mixed is the same as the 
sum of the original colors.  The more colors you mix, 
the brighter it becomes.  If you mix “light’s three 
primary colors”, red (R), blue (B) and green (G) in even 
amount, it will become white.
