Scholarly Significance
Anchor Taro Okamoto's public art legacy and postwar Japanese avant-garde with the Tower of the Sun — the defining monument of Japan's high-growth era and Expo '70.
Notes
- ·Commissioned for Expo '70 (Japan World Exposition, March–September 1970, Suita, Osaka); theme 'Progress and Harmony for Mankind'.
- ·Architect Kenzō Tange designed a 'Festival Plaza' covered by a giant roof; Okamoto's tower intentionally pierced through the roof, creating a rupture in Tange's modernist geometry.
- ·The tower has four faces: Gold Sun (top, future), Sun of Now (front, present), Black Sun (back, past), and White Sun (bottom, prehistory — inside the tower).
- ·The interior contains the Tree of Life sculpture representing biological evolution from amoeba to human.
- ·After Expo '70 most pavilions were demolished; the Tower was nearly destroyed but preserved following a public campaign. Opened for interior visits in 2018 after restoration.
- ·The tower was designed by a person who had witnessed the Jomon ceramics at Tokyo National Museum (1952) and proclaimed the Jomon aesthetic Japan's primordial vitality — the tower embodies that thesis.
- ·Japan's governing polity at the time of creation: the Liberal Democratic Party-led Japanese state (Showa period).
