During the Japanese occupation period, most locals decided to enter and hide into the forest. From there they set up strategies against the Japanese government. At that time they lived by making cassava, sweet potatoes and root of wood as the main food. Those who live outside the forest are still able to get food supplies and have to get water from energy and rivers.

     When Japanese troops arrived in Kulai from the North, most of them based in the new Kulai market were built. The Kulai Police Station, the Tan Yoke Fong residential bungalow, the cinema and airport in Kulai Besar have also been used as a base for Japanese troops. They have implemented the 'Gold Donation Campaign' by demanding the Chinese donate gold coins and British currencies to the Japanese army. The rebellion of anti-Japanese groups has caused the Japanese military to direct the locals of the Malays and the Chinese to create control teams that patrol at night.

     Kulai town continues to grow despite the various black events on its face. Several new settlements have begun to exist since communist period. The communist appearance of Malay community began to appear after the end of the communist era. This was followed by the opening of Felda Taib Andak a few years later. Hakka Association building built in 1920 is the first building built in Kulai town.
