Kochani's history dates back to the Roman Empire, with archaeological findings such as the Pantelej monument from the 4th century CE indicating early settlement and continuous habitation.

The town is strategically positioned in the fertile Kočani Valley along the Kočanska River, a tributary of the Bregalnica, defining its geography and agricultural prominence.

Under Ottoman rule, Kochani evolved into a significant administrative and trading hub, recognized for its vibrant bazaars and strategic location connecting various regions.

Demographically, Kochani recorded a population of 24,632 inhabitants in the 2021 census, with ethnic Macedonians constituting the majority, alongside smaller communities like Roma and Turks.

The town is famously known as the "rice capital" of North Macedonia, due to its ideal microclimate and extensive irrigation systems supporting the cultivation of high-quality rice in the Kočani Field.

The economy primarily revolves around agriculture, especially rice farming and processing, but also includes textile manufacturing, food processing, and a developing sector in small and medium-sized enterprises.

Population growth trends in Kochani showed a steady increase throughout the 20th century, reflecting industrialization and urbanization, before stabilizing and experiencing minor fluctuations in recent decades.

The annual "Days of Rice" festival, held every October, is a celebrated cultural event showcasing local traditions, culinary specialties, and agricultural achievements related to the town's most important crop.

The Kočani Clock Tower, an Ottoman-era edifice located in the town center, stands as a prominent historical landmark and a testament to the town's rich architectural heritage.

While Kochani itself does not host a UNESCO World Heritage Site, its surrounding region, particularly the Osogovo Mountains, is appreciated for its natural beauty and cultural significance, attracting eco-tourism.

Traditional Kočani cuisine heavily features rice-based dishes, with "Kočanski oriz so meso" (Kočani rice with meat) being a local specialty that highlights the quality of locally grown rice.

Kochani played a role in the Macedonian National Revival, with local figures and educational initiatives contributing to the broader awakening of national consciousness in the late 19th and early 20th centuries.

The Monastery of St. Panteleimon, nestled on the slopes of the Osogovo Mountains overlooking the valley, serves as a significant spiritual and historical landmark for the local community.

The town is home to several educational institutions, including primary and secondary schools, which contribute to the intellectual development and skill training of the regional youth.

Archaeological excavations at sites like Gorno Gradiste near Dolno Gradiste village have unearthed remnants of ancient settlements, confirming Kochani's long history of human presence and its cultural evolution over millennia.
