Try Dealroom →, a Japanese developer of marine drones, making it a group company. The electronics maker from Chiba announced the deal on October 23, 2026, with terms undisclosed. Homura, based in Iwate, builds unmanned surface vehicles (USVs) and autonomous surface vehicles (ASVs).
What each side brings: Futaba contributes wireless communications, remote control, industrial servo, and aerial drone technology built up over decades. Homura adds domestically made surface drones, autonomous navigation, and water-domain expertise. Together they aim to build a Japanese unmanned-systems platform spanning air and water.
Why now? Ageing social infrastructure and labour shortages are driving demand for unmanned inspection, disaster response, and maritime monitoring. Futaba frames the deal as part of its push into automation, extending its reach from the air into water.
What's the endgame? The company wants to combine aerial and surface drones into integrated inspection, monitoring, and disaster-response systems for rivers, ports, dams, and sewers. Chief executive officer Motoaki Arima pointed to pairing Futaba's wired-power drones, which can fly continuously for 100 hours, with Homura's USV technology.
Arima also flagged security applications. "Monitoring of military activity at sea and observation of abnormal weather" will raise the importance of surface-domain technology, he said, calling Homura a key partner.
Who is Homura? Founded in 2016 in Iwate with reconstruction after the 2011 earthquake in mind, it has a capital of US$1.72M as of December 2025. It first exhibited a USV at Slush Tokyo in 2018 and launched the Japan Surface Drone Association in 2023.
