A closer look at the industrial and logistics real estate market in Ayutthaya — a historic province roughly 80km north of Bangkok whose modern economy runs on Rojana Industrial Park and a cluster of nearby estates hosting a mature, decades-old base of Japanese manufacturers. Builds on our national industrial & warehouse overview. General information only, never paid placement.

Ayutthaya's industrial identity runs through Rojana Industrial Park, a Japanese-Thai joint venture founded in 1988 and roughly 60% occupied by Japanese manufacturers including Honda, Nikon and Panasonic — a mature, stable base rather than a fast-expanding one. Rent generally undercuts Eastern Economic Corridor and Bangkok-perimeter logistics stock, but any tenant should ask directly about post-2011 flood-defense infrastructure given the province's flood history.
See our Pathum Thani industrial deep dive for the closer-to-Bangkok side of this same northern corridor, and the Ayutthaya city guide for the province's residential, heritage and transit context.
Rojana Industrial Park's identity is inseparable from its Japanese-Thai ownership structure and the manufacturing base it attracted from the start. Established in 1988 as a joint venture between Nippon Steel & Sumikin Bussan Corporation and the Vinichbutr Group, the estate built a reputation among Japanese manufacturers for reliable estate management and utilities, which snowballed into a dense supplier ecosystem — once Honda, Nikon and Panasonic committed major facilities, component suppliers and second-tier manufacturers followed to stay close to their anchor customers. That density is now the estate's main competitive advantage over newer estates elsewhere in the country: a manufacturer locating at Rojana inherits an established, Japanese-fluent supply chain rather than building one from scratch. It has grown steadily rather than rapidly since — a mature, stable base of company-assigned staff and long-tenured suppliers rather than a fast-expanding frontier estate.
Ayutthaya's industrial history has one defining event: the 2011 floods, Thailand's worst in decades, which submerged the historical park and shut down Rojana and several other nearby industrial estates for months, disrupting global supply chains for electronics and automotive components that ran through the province. In the years since, Rojana and neighboring estates invested in dikes, levees and drainage-pump systems specifically to protect industrial zones, and the estate has continued operating without a repeat closure since 2011. That said, flood risk in Ayutthaya hasn't been eliminated — the historic island and outer rural districts flooded again as recently as October–December 2025 — so any prospective tenant or investor should ask a landlord directly about current flood-defense specifications and insurance coverage rather than assuming the post-2011 upgrades fully remove the risk.
As a general pattern rather than a live quote: ready-built factory and warehouse space in and around Rojana Industrial Park has historically priced below comparable Grade A logistics stock in the Eastern Economic Corridor or Bangkok-perimeter estates like Samut Prakan, reflecting Ayutthaya's positioning as a mature, established manufacturing base rather than a premium logistics location. Rent is quoted per square metre per month, with estate common-area and utility charges typically billed separately — always confirm whether a quoted figure is net or all-in before comparing sites. Larger built-to-suit facilities generally involve either outright land purchase (for BOI-promoted manufacturers eligible for freehold) or long-term land lease from the estate, alongside the construction cost of the factory itself. Deposit plus advance rent at signing is standard practice for smaller ready-built units. These are directional patterns, not current figures — for actual rent quotes and land pricing, work from a licensed commercial or industrial agent's latest report or contact Rojana Industrial Park directly.
Standalone industrial or commercial land in Ayutthaya generally falls under the standard restriction on foreign land ownership, meaning a foreign-owned company typically needs a long-term lease or a Thai-majority corporate structure to occupy it directly — the same baseline rule that applies to commercial land nationwide. Inside a licensed IEAT-linked estate like Rojana, the picture can differ: manufacturers with activities promoted by the Board of Investment can in some cases access freehold land ownership tied to the promoted activity, a route generally unavailable on standalone land outside a licensed estate — similar in principle to the freehold-via-BOI path available at estates like Map Ta Phut or Amata City Rayong. Eligibility depends on the specific promoted activity and current BOI policy, so confirm structuring options directly with the BOI and have a Thai-qualified lawyer review any lease or land-purchase agreement before signing. Full detail on IEAT estates, Free Zone status and BOI incentive tiers is covered on the national industrial overview.
