About this position

The National Institute for Environmental Studies (NIES) is recruiting a tenure-track fixed-term researcher for work on sustainable waste management systems, with a strong focus on radioactive cesium, final disposal, landfill disposal, and technologies for reducing the burden of future disposal.

The position is based in the Fukushima Regional Collaborative Research Center in Fukushima Prefecture, Japan, with possible relocation to Tsukuba or Otsu depending on institutional needs. The research themes include: (1) understanding elution characteristics of radioactive cesium and other substances from heat-treated fly ash, developing solidification technologies using cement and other binders, and advancing ash washing, adsorption, concentration, and stabilization processes; and (2) developing solidification/immobilization technologies for landfill waste, landfill disposal methods, and broader waste treatment systems and institutional frameworks that can accommodate future regulated substances such as PFAS.

This opportunity is especially relevant to candidates in environmental engineering, civil engineering, sanitary engineering, nuclear engineering, materials engineering, and related environmental systems fields. Applicants must hold a doctoral degree by the start date (or have equivalent achievements), have broad research experience and achievements aligned with the advertised themes, and possess Japanese and English communication and research dissemination skills equivalent to JLPT N1 or higher.

Funding is a salaried full-time research appointment with an annual income of 7–10 million yen, including bonuses, and the contract may lead to permanent researcher status if performance is outstanding. The appointment is scheduled to begin on 2027-04-01, with an application deadline of 2026-11-25. Applicants should review the recruitment PDF, prepare the required documents, and follow the institution’s web application instructions. Recommendation letters are required from two referees.
