Masai has gone through vigorous development which has transformed the town into one of the most populous towns in Johor. The Masai Chinese Primary School now has more than 5000 pupils.
Bandar Seri Alam is the business centre for Masai, with

Public Bank, Bank Simpanan Nasional and
Bank Rakyat and hotels.
Jalan Masai Lama is the main road connecting
Johor Bahru to towns to the east of Masai such as Kota Masai,
Kong Kong and
Pasir Gudang. Meanwhile, Masai is also the name of the district, Masai District with post code of 81750, where the town is situated. Masai district is consist of Masai town, Bandar Seri Alam, Taman Rinting, Kota Puteri, Plentong, Permas Jaya and others. Due to location, Tanjung Langsat industrial area is quite near to Pasir Gudang, so it's categorized as Pasir Gudang district. However, the weird thing for Tanjung Langsat village is that the village is categorized as Masai district due to historical development. Crime rates are notably high in the area since the 1970s due to high unemployment rates and relatively under-development in the town since the 1980s. ==Education==
