Japan’s parliament elects Sanae Takaichi as nation’s first female prime minister

By / / Good News For Humankind

Japan has reached a monumental moment in its long democratic history by electing Sanae Takaichi as its first female Prime Minister. Takaichi, a well-known figure with a long tenure in parliament, shatters a critical barrier in gender representation at the highest level of government. This election, coming from a historically male-dominated political structure, is a potent source of inspiration for women in public service across the Asia-Pacific region.

Japan opens landmark osmotic power plant

By / / Good News For Humankind

A groundbreaking development has put osmotic power back on the map as a viable clean energy source. Japan has opened the world’s second large-scale osmotic power plant, a facility in Fukuoka prefecture that turns the natural mixing of freshwater and saltwater into electricity. This milestone proves that this technology is moving beyond the lab. It offers a new model for continuous, emissions-free power generation that can be integrated into existing infrastructure, providing a stable complement to intermittent sources like solar and wind.

Japan to begin clinical trials for artificial blood

By / / Good news links

For decades, a shrinking population and an aging society in Japan have led to fewer blood donors. This situation is especially dire during disasters or in remote regions, where matching blood types and storing donated blood are logistical nightmares. Recognizing this, researchers at Nara Medical University are developing a safe, effective artificial blood that could be administered to anyone, anywhere, at any time. Clinical trials begin this year, with practical use expected by 2030.

Tokyo to make daycare free for all preschool children

By / / Good news links

The world’s most populous city plans to make daycare free for all preschool children starting in September, the city governor has announced. The move aims to reduce the financial burden on families by expanding a policy of free daycare for second-born and subsequent children to first-borns as well. While many developed countries are struggling with low birth rates, the problem is particularly acute in Japan where the population has been declining for years.

Japanese court rules marriage equality ban unconstitutional

By / / Good news links

The Fukuoka High Court of Japan has become the third of Japan’s eight high courts to rule that the government’s policy against same-sex marriage is unconstitutional. High Court Judge Takeshi Okada ruled that civil laws forbidding same-sex marriages violate the nation’s constitution, saying, “There is no longer any reason to not legally recognize marriage between same-sex couples.” However, he noted that any change in national marriage laws must be decided by Japan’s legislature, known as the National Diet.

Japanese researchers develop world-first stem-cell treatment that restores vision in humans

Kohji Nishida, an ophthalmologist at Osaka University in Japan, and his colleagues used an alternative source of cells — induced pluripotent stem (iPS) cells — to make the corneal transplants. They took blood cells from a healthy donor and reprogrammed them into an embryonic-like state, then transformed them into a thin, transparent sheet of cobblestone-shaped corneal epithelial cells. After the transplants, all four recipients showed immediate improvements in their vision and a reduction in the area of the cornea affected by limbal stem-cell deficiency. The improvements persisted in all but one recipient, who showed slight reversals during a one-year observation period.

World’s first wooden satellite, developed in Japan, heads to space

By / / Good news links

LignoSat, developed by Kyoto University and homebuilder Sumitomo Forestry, opens new tab, will be flown to the International Space Station on a SpaceX mission, and later released into orbit about 250 miles above the Earth. Named after the Latin word for “wood”, the palm-sized LignoSat is tasked to demonstrate the cosmic potential of the renewable material as humans explore living in space. Decommissioned satellites must re-enter the atmosphere to avoid becoming space debris. Conventional metal satellites create aluminum oxide particles during re-entry, but wooden ones would just burn up with less pollution.

Second Japanese high court rules in favor of same-sex marriage

By / / Good news links

A Tokyo high court in Japan recently ruled that the government’s policy against same-sex marriage is unconstitutional. The ruling marks the second time that one of the nation’s eight regional high courts has ruled in favor of marriage equality. The Tokyo high court ruled that the country’s ban on same-sex marriage is “a groundless legal discrimination based on sexual orientation” that violates the constitutionally guaranteed right to equality and dignity regardless of sex.

Japanese scientists reverse Alzheimer’s synapse damage in mice

By / / Good news links

Scientists from the Okinawa Institute of Science and Technology say they have reversed the signs of Alzheimer’s disease in lab mice by restoring the healthy function of synapses, critical parts of neurons that shoot chemical messages to other neurons. If the treatment successfully survives the gauntlet of clinical studies with human participants, it could potentially lead to a groundbreaking new treatment for humans suffering from the deadly disease.

The satellite dubbed LignoSat, a collaboration between Kyoto University and the company Sumitomo Forestry, is reportedly slated for launch in September onboard a SpaceX rocket. If successful, the tiny device — just four inches on each side — could represent a major breakthrough in space sustainability efforts. The idea is that it’ll burn up entirely upon reentry, vastly reducing its environmental impact compared to traditional metal spacecraft.
