On a Tokyo street corner, in the pouring rain, a swelling crowd gathered with drenched placards and sodden flags. On one of them was written just two words, in big bold Japanese kanji characters: "No War".

It's a sentiment that is gaining more and more volume in Japan, which is currently witnessing its largest anti-war protests in decades.

Since coming to power in October 2025, Japanese Prime Minister Sanae Takaichi has taken major steps away from the country's post-war pacifist stance, lifting long-standing restrictions on arms exports and expanding Japan's military role abroad.

The government says such moves are necessary in an increasingly tense region. But for many residents, it's raising alarm.

As fears grow that Japan is becoming a war-capable nation, protests are gaining momentum.
