In 2017, the city of São Paulo turned 463 years old and, to commemorate the occasion, the city government restored the monument to the 80th anniversary of Japanese immigration. The work, signed by Tomie Ohtake, is one of the most important in the artist's career.
The restoration of the sculpture, located on Avenida 23 de Maio, was carried out through the Cidade Linda program
— a partnership between the Tomie Otake Institute and the Coral paint brand. After the last repainting, seven years ago, the work suffered some degradation such as graffiti and cracks, in addition to pollution residue.
The monument symbolizes the arrival of the first group of Japanese immigrants in Brazil and their overcoming after the difficult adaptation in the city of São Paulo, more specifically in the neighborhoods of Saúde, Jabaquara and Liberdade. The four waves rising from the ground represent the four generations of Nikkei (descendants of Japanese people), who are Issei (born in Japan), Nisei (sons of Japanese people), Sansei (grandsons) and Yonsei (great-grandsons). According to the author of the work, the waves also represent
progression and continuity.
