The day was dominated by the passage of two contentious bills. In the morning, the flag desecration law was enacted, criminalizing damage to the national flag with penalties including imprisonment, amid criticism over free speech. Shortly after, the Imperial Household Law amendment passed, allowing adoption of male-line males from former imperial houses to secure succession while preserving male-only lineage. Both votes saw opposition from some parties and media, with Sankei and Yomiuri noting the swift deliberation and lack of unanimous consent. Meanwhile, the Nikkei plunged over 4,100 points intraday—its third-largest drop—triggered by a global AI stock rout, with Kioxia halving in value. Heavy rain warnings were issued for Kanto, and a missing 5-year-old boy was found dead in a river in Kagoshima.
