Sadiatec Co.

What Sadiatec Co. does

Sadiatec Co., Ltd. is a Tokyo-based private company founded in 2005 (originally as Sadia Intertec Company Limited) that connects Bangladeshi workers and students with employment and education opportunities in Japan. The company operates two distinct business lines: (1) an HR solutions platform covering Technical Intern Training Program (TITP), Specified Skilled Worker (SSW), and student visa support, anchored by its wholly owned Sadia Nihongo Training Center in Dhaka that delivers a 350-hour curriculum from N5 to N2 levels; and (2) a telecommunications business spanning the Safetalk international calling card brand (flagship since 2002), Pocket WiFi and Mobile SIM rentals powered by SoftBank's network, prepaid SmartPit rechargeable cards distributed through Lawson, FamilyMart, and Ministop convenience stores, and hosted softswitch/VoIP solutions resold to SMBs and telecom operators.

Sadiatec monetizes through a mix of placement and recruitment fees (HR), recurring language-training tuition, daily/monthly Pocket WiFi subscriptions (¥500/day, ¥4,000/month), usage-based calling card consumption, and managed VoIP/PBX services on a rental basis. Distribution combines a direct recruitment team with offices in Tokyo (Akihabara headquarters), Dhaka (Uttara), and Pabna; dealer/reseller networks for calling cards; convenience-store recharge for telecom products; and community-led digital channels including DoshdikTV and WhatsApp support. Customer testimonials reference successful student visa, SSW career placement, and JLPT preparation outcomes for Bangladeshi candidates.

The company holds an unusually dense regulatory credential stack for its size: General Worker Dispatch and Paid Employment Placement licenses (Aichi Labour Bureau, 2015), Technical Intern Sending Organization (Bangladesh, 2019), SSW Registration Supporting Organization (Japan, 2019), ISO 9001 (SGS), Privacy Mark (JIPDEC), and brand trademark (Japan Patent Office, 2007). Founded and led by Md Sanaul Haque (President & CEO) with Kansuke Yoshida as GM of HR and a Lecturer at the language center, Sadiatec is privately held with no disclosed venture funding and registered capital of ¥30,000,000.

Others

• LITALICO Inc. Japanese company operating employment-support services for people with disabilities and educational services, alongside a workforce-development platform.

Direct peers

• Global Power Co., Ltd. Japan-based firm specializing in placing Vietnamese, Indonesian, Filipino, and other Asian workers into Japanese TITP and SSW programs, with end-to-end language training and post-arrival support.

Comparable in cross-border recruitment and Japan-based employer matching, though focused on professional rather than SSW/TITP labor and not specializing in Bangladesh.
