Abandoned Bamboo Forests: Japan's New Mulcher "TakeKaruGon" Tackles a Growing Environmental Crisis

Japan's bamboo forests cover roughly 400,000 acres, and unmanaged groves keep spreading, raising landslide risks and damaging ecosystems. Taguchi Industrial from Okayama has answered with the "TakeKaruGon" - a domestically-made mulcher attachment for hydraulic excavators that shreds bamboo, large trees, and stumps in one machine. Discover how this innovation tackles one of Japan's most overlooked environmental crises.

Flying Cars Coming to Japan: Startup AirX Orders eVTOL Aircraft for 2029 Launch in Tokyo and Osaka

Japanese startup AirX has signed a binding order with Brazil's Eve Air Mobility for two eVTOL "flying car" aircraft, with options to expand to 50 units in a deal potentially worth $150 million. Targeting 2029 for sightseeing and last-mile transport services in Tokyo and Osaka, this agreement marks a major milestone in Japan's push toward urban air mobility — following successful demo flights at Expo 2025 Osaka.

Nuclear Ship to Ocean Research Vessel: How Japan's First Atomic Ship "Mutsu" Was Reborn as the World-Class Research Ship "Mirai"

Japan's first nuclear-powered ship "Mutsu," launched in 1969, was plagued by a radiation leak incident and fierce public opposition. Yet engineers cut the hull apart, removed the reactor, and spent roughly $1.3 billion (in today's value) transforming it into "Mirai" — one of the world's largest ocean research vessels. Over 28 years, Mirai sailed 2.3 million km (58 trips around Earth), pioneered Arctic research, and even surveyed Fukushima's nuclear contamination. Retired in December 2025, its story of dramatic reinvention now passes the torch to the icebreaking successor "Mirai II."

Rockoon Launch: Japan's AstroX Raises $15M to Send Satellites to Orbit via Balloon-Launched Rockets

Japanese startup AstroX has raised $15 million in Series A funding to develop its revolutionary Rockoon launch system — using high-altitude balloons to carry rockets to the stratosphere before firing them into space. Based in Fukushima's Minamisoma, the company aims to reach space by 2026 and achieve orbital insertion by 2029, challenging the global space launch industry with a low-cost, flexible alternative.

Power-Generating OLED: Japanese Researchers Overcome Light Emission and Solar Power Trade-off in Single Device

A joint team from Chiba University, NHK Science & Technology Research Labs, and Kyoto University has developed an organic EL device capable of both light emission and solar power generation. Using innovative MR-TADF materials, they overcame the long-standing trade-off between emission and power conversion efficiency, achieving the world's first blue light-emitting power-generating device. Applications include self-powered displays and battery-free sensors.
