A new school built by The Japan Club, now known as The Japanese Association, opened at 155 Waterloo Street in 1920.

When the Japanese occupied Singapore, the government opened the Shonan First People's School.

[3] A Japanese school facility opened in 1964 at what is now the Newton Post Office on Bukit Timah Road.

In April 1968 the school moved to Swiss Cottage Estate, the black and white bungalow.

Beginning in April 1998 the two primary schools began functioning as separate 1–6 campuses with different principals.

The campus includes an auditorium, a gymnasium, two libraries, an audiovisual studio, a laboratory, a sports field, a computer laboratory, a swimming pool, two playgrounds, music immersion rooms, a pet corner, and rooms for specialised studies including home economics, music, and arts and crafts.

The campus includes heritage rooms for the display of historical items and books and photographs valued by the community.
