What Ocean Solution Technology does

Ocean Solution Technology Co., Ltd. (オーシャンソリューションテクノロジー株式会社) is a Sasebo, Japan-based marine-IT company founded in December 2017 that builds software and hardware products for the fisheries sector. Its core product, Triton's Spear (トリトンの矛), is a SaaS platform that ingests vessel GPS tracks via IoT, automatically generates fishing operation diaries using AI-based fishing method estimation, and overlays oceanographic data to support fishing-site decisions, electronic catch reporting, and TAC-compliant resource management. The company complements this software with proprietary hardware, including the Maclir (マクリル) underwater sensor for measuring bottom-layer water temperature and salinity at depths up to 500 meters, and the Artemis rescue position notification system co-developed with Sasebo Kokai Sokkisha, plus a RESCUE module for maritime safety inside Triton's Spear.

The company's technical differentiation rests on three pillars: exclusive integration of JAXA's SAMRAI satellite for all-weather observation of sea surface salinity, temperature, and wind speed; high-precision vessel positioning via Japan's Quasi-Zenith Satellite (Michibiki); and claimed world-first AI-based automation of fishing operation logs. AI capabilities extend to red tide prediction (over 90% reported accuracy), anomaly detection for man-overboard events, and an emerging IUU-fishing identification capability (Smart Tasking 2.0) funded through the JAXA Space Strategy Fund. Strategic partners include JAXA, KDDI, Mitsubishi Electric, Meta Systems Laboratory, JICA, and multiple universities; certifications include ISO/IEC 27001 (information security) and ISO 9001 (quality), supporting eligibility for Japanese government contracts.

The business model combines subscription-based SaaS access to Triton's Spear, hardware sales of Maclir, professional services and system integration, and data monetization through aggregated operational and ocean data shared with government and research institutions. Customers are segmented across individual fishermen and SMB fishing corporations, fishing cooperatives, Japanese municipal and prefectural government fisheries departments, national agencies (Fisheries Agency, METI, Cabinet Office, JAXA), and academic institutions. Distribution is direct enterprise field sales supplemented by grant-funded demonstration projects; pricing is contact-based and not publicly disclosed. In April 2024 the company merged with Magnetic Square Ltd. to add in-house hardware capability, and as of 2024-2025 it has begun international expansion through JICA-supported pilots in Fiji and Palau and a JAXA-funded feasibility study targeting ASEAN IUU fishing markets.

Core offering

Ocean Solution Technology develops and sells AI- and IoT-based fisheries management software under its flagship Triton platform (Triton's Spear / トリトンの矛). The platform digitizes fishing operations through IoT vessel tracking, automatically generates fishing operation diaries from GPS trajectories using proprietary AI, and combines satellite-derived ocean data (JAXA SAMRAI) with on-water sensor data for fisheries forecasting and resource management. Supporting offerings include the Maclir underwater environment sensor, the Artemis man-overboard detection system, and the RESCUE maritime safety module.

Product overview

Ocean Solution Technology offers a portfolio of fishery-focused software and hardware products centered on the 'トリトンの矛 (Triton's Spear)' platform. Triton's Spear is the core SaaS product that combines IoT vessel tracking with AI-powered automatic operation diary generation and ocean/satellite data visualization. The portfolio includes the underwater measurement device 'マスクリル (Maclir)' for bottom-layer ocean data collection, the rescue module 'RESCUE' for maritime safety, and the emergency notification system 'アルテミス (Artemis)' developed with Sasebo Kokai Sokkisha. The products are designed to work together: Maclir collects physical ocean measurements, while Triton's Spear aggregates all data (GPS tracks, satellite ocean data, sensor readings) into a unified platform serving fishermen, local governments, public agencies, and research institutions. A new IUU fishing detection system 'Smart Tasking 2.0' is under development with JAXA funding.
