Founded in 2023 and headquartered in Osaka, Japan, A-wave focuses on digital medical technologies for the growing population of chronic heart-failure patients. Its flagship product is an at-home monitoring system that applies cardiology specialist diagnostic know-how to continuously track patient condition and flag deterioration triggered by excess salt intake, overwork, or other stressors. The company aims to establish a medical framework that enables early intervention and thereby lowers rehospitalization rates. Proceeds from its latest funding will finance a nationwide clinical trial of the device in partnership with multiple Japanese medical institutions. Insights from the trial will be used to refine the system and prepare it for practical commercialization. A-wave also plans to deepen collaborations with relevant academic societies and healthcare providers to build a robust deployment ecosystem. No revenue or user metrics have been disclosed to date.

AstroX is a Japanese private space startup founded in May 2022 that is building a Rockoon system, in which a balloon carries a rocket to high altitude before launch, to provide low-cost, high-frequency and rapid-response small-satellite deployment. Headquartered in Minamisoma, Fukushima Prefecture, the company pursues the vision of restoring “Japan as No. 1” in space development. Demand for small-satellite launches is rising sharply, yet Japan currently depends almost entirely on foreign launchers; AstroX aims to fill this gap domestically. In December 2025 the firm successfully conducted its first launcher experiment, validating separation mechanics for its rocket mount. Proceeds from its Series A financing will be used to accelerate Rockoon R&D and expand engineering talent, with the goal of reaching space by 2026. Total Series A funding now amounts to ¥2.32 billion, providing capital for continued technology development and operational scaling. No revenue or customer metrics were disclosed in the article.
