株式会社アステック

What 株式会社アステック does

株式会社アステック (Astech Co., Ltd.) is a privately held Japanese electronics design and manufacturing firm founded on January 5, 1996, headquartered in Isesaki, Gunma Prefecture, with approximately 14–15 employees and a 2,700 sqm factory site that includes reinforced-concrete production buildings and a warehouse. The company's core competency is microcontroller application development (マイコン応用電子機器開発) — designing, prototyping, and manufacturing embedded-control devices spanning consumer health products, educational toys, automated planters, mechanical demonstration clocks, optical instruments, and OEM/industrial electronics. Signature offerings include the Bibou (備忘) medication non-adherence prevention device (¥3,000 retail), the Auto Planter Clean Green automated plant-care system, custom karakuri mechanical clocks, a planetarium projector capable of rendering ~25,000 stars, and a gait-training machine co-developed with Gunma University School of Medicine.

Astech operates a hybrid business model with three distinct revenue streams: direct-to-consumer product sales through its own Japanese e-commerce website and telephone/fax ordering; OEM/B2B contract manufacturing of custom-branded microcontroller products for other companies; and bespoke institutional commissions (e.g., karakuri clocks for pharmacies, schools, and hospitals; game machine assembly services). Pricing is unit-based with no subscription tiers, and the firm holds a medical device manufacturing license, enabling regulated health-product work. The firm relies on a curated network of partner factories in Japan (Joetsu Electronics, MK Electronics, Yoshikaga, Izumi Electric) and Shenzhen (Meina Ltd.) for PCB assembly and production scaling, while maintaining in-house design, prototyping, and small-batch manufacturing at its Gunma facility.

Customer engagement spans individual Japanese consumers (primarily elderly users of the Bibou device and parents purchasing educational toys), B2B/OEM clients in automotive, medical, and educational publishing, and institutional customers (hospitals, pharmacies, schools) commissioning custom installations. Marketing channels center on the company's own e-commerce site, supplemented by trade-show participation (Agro Innovation 2012, Made in Isesaki 2015, Tokyo Big Sight SME exhibition 2005), earned media coverage in regional and national Japanese press (Nikkan Kogyo Shimbun, Asahi Shimbun, Nihon Keizai Shimbun, Jōmō Shimbun), and a public idea-solicitation program. Two Good Design Gunma awards (2005, 2006) provide regional design credibility, and the firm is led by Chairman Tashiro Kameo (田島 亀夫) and President Gotō Keiji (後藤 圭司), who assumed the presidency in January 2016.

Products and services

• Bibou (備忘) Medication Reminder A consumer health device that uses a dual-color LED indicator (green for upcoming dose, red for missed dose), a piezoelectric buzzer, and a clip mechanism detecting when medicine packaging is opened, to help users reliably remember up to 5 daily medication times. Priced at ¥3,000 per unit with shipping included.
• Auto Planter Clean Green (クリン グリン) An automated planter that creates optimal growing environments for plants, featuring a DC12V power supply, LCD control box, peristaltic pump, automated window ventilation motor, LED grow lighting (red:blue 20:10 ratio), 15W freeze-prevention heater, and a closed-loop water recirculation system.
