Otsuchi Town, Iwate Prefecture/N Co., Ltd. Head Office Manufacture

Episodes during the construction period

• The construction period was only three months, and temporary accommodations were constructed near the site.
• Due to rising construction costs, only a factory was built. Unable to construct a cold storage facility, container freezers were used.
• Construction began after the earthquake with no residents living in the surrounding area and no water or sewage system in place.
• Four wells were dug, but they were unusable due to salt contamination.Secured from an old well 250m away.
• The septic tank was installed semi-underground due to high seawater level caused by ground subsidence.
• Construction began without water and electricity during the construction.

Proposal for “HACCP compatible factory”
What is HACCP?

It is a method of sanitation management that ensures product safety by analyzing in advance hazards such as microbial contamination that may occur at any stage of the food manufacturing and processing process, determining critical control points based on the results of the analysis to determine what measures should be taken at what stage of the manufacturing process to obtain safer products, and continuously monitoring these critical control points. This is a method of sanitation control that ensures product safety through continuous monitoring. Compared to conventional hygiene control based on sampling inspections, this method is more effective in preventing the shipment of problematic products, and also makes it easier to track down the cause of the problem.
