Company assessmentBroad incumbents
- Accenture Japan: Global consultancy with major Japan operations delivering IT services, Salesforce, and enterprise transformation. Competes for the largest DX deals in the same customer base.
- NTT Data: Japan's largest system integrator with comprehensive IT services, cloud, and managed services offerings. Competes for the same enterprise RFPs but at vastly larger scale and broader capability set.
- Internet Initiative Japan (IIJ): Established Japanese IT infrastructure and managed services provider. Overlaps with SERAKU's cloud/infrastructure practice but focused more on network services and hosting.
- Nomura Research Institute (NRI): Larger Japanese IT services and consulting group with broader portfolio including financial services solutions. Overlaps with SERAKU on consulting and DX but operates at meaningfully larger scale.
Direct peers

- Future Corporation: Japanese IT consulting and managed services firm with strong practice in ERP/CRM implementation and DX advisory. Similar mid-market enterprise focus and services-led model.
