Develop accelerator technology for the Charge Stripper Ring planned at RIKEN's RI Beam Factory. The appointment contributes to heavy-ion accelerator construction and future operation.

Develop high-power solid-state radio-frequency amplifiers for a new heavy-ion accelerator ring. The research supports the planned upgrade of RIKEN's RI Beam Factory.

The FQSP Distinguished Fellowships support independent theoretical research spanning fundamental physics and chemistry, mathematics, quantum information and nonequilibrium science. The programme gives early-career researchers scope to pursue their own questions across laboratory boundaries. Recruitment requires an initial nomination by a referee who can assess the candidate’s research ability. Referee registration is due November 13, 2026; the subsequent candidate application and recommendation documents are due December 14, 2026. The successful scientist is employed at RIKEN’s Wako campus.

RIKEN seeks a research scientist in Ryuhei Nakamura’s Biofunctional Catalyst Research Team to advance water-electrolysis systems for green-hydrogen production. Research may focus on non-precious-metal oxygen-evolution catalysts, in-situ spectroscopy of reaction and degradation mechanisms, or computational analysis. The project is scheduled through March 2028. The position is based in Wako and requires independent research and collaboration. Recruitment is explicitly open until filled; the vacancy provides the application-upload route and submission instructions.

One research appointment in the Imperfect Information Learning Team at RIKEN’s Center for Advanced Intelligence Project. The team develops machine-learning methods that remain effective when training information is incomplete or otherwise imperfect. Work spans supervised, unsupervised and reinforcement learning, including algorithm design, theoretical analysis and experimental evaluation. The Tokyo-based position also involves scientific collaboration and mentoring. Applications remain open until the position is filled.

The Nuclear Chemistry Group at RIKEN’s Nishina Center for Accelerator-Based Science seeks one postdoctoral researcher, research scientist or Technical Staff I. The AMED cancer research project develops production and use of radioisotopes with the heavy-ion accelerators at the RIKEN RI Beam Factory. Researchers will develop isotope production and utilization techniques, investigate applications, distribute radioisotopes and maintain production equipment and hot laboratories. Technical staff will support production, quality evaluation and distribution, manage radioisotopes and chemicals, and sup

Study nuclear data needed to evaluate transmutation processes. The research-scientist appointment contributes to RIKEN's programme on the nuclear reactions relevant to transforming long-lived nuclides.

Support research on cold-atom systems for quantum computing. The part-time appointments contribute to laboratory activities in RIKEN's quantum-control and measurement programme.

Investigate functional magnetic materials within RIKEN's emergent-matter research programme. The postdoctoral appointment connects materials development with experimental studies of magnetic properties.

Conduct research in quantum materials at RIKEN's Center for Emergent Matter Science. The appointment is available at postdoctoral or research-scientist level according to qualifications and experience.

Conduct theoretical research on topological phenomena in condensed-matter systems. The postdoctoral appointment joins RIKEN's emergent-matter theory programme.

Develop multimodal artificial-intelligence methods within RIKEN's research programme. The appointment contributes computational methods and frameworks for integrating different forms of scientific data.

Research computing platforms and methods that improve the efficiency of machine-learning workloads. The appointment contributes to RIKEN’s AI for Science Platform and the optimisation of scientific computation.
