Japan will immediately begin drafting amendments to the Imperial House Law to ensure a sufficient number of royal family members [1].
This move addresses long-term concerns regarding the sustainability of the monarchy. By revising the legal framework, the government aims to prevent the royal lineage from shrinking to a critical level, ensuring the stability of the throne for future generations.
Chief Cabinet Secretary Minoru Kihara announced the policy during a press conference on June 11, 2026 [1]. Kihara said the decision follows a general consensus reached by the legislature regarding measures to secure the number of imperial family members [1].
"We will immediately work on creating the bill," Kihara said [2].
The administration intends to move quickly to formalize these changes. According to LDP Upper House official Hitoshi Isozaki, the bill is expected to be submitted to the Diet by late June 2026 [3].
The process follows a period of deliberation among lawmakers to determine the most viable path for maintaining the royal household. The government said that amending the Imperial House Law was the necessary step to reflect the legislative will, and the needs of the monarchy [1].
“"We will immediately work on creating the bill,"”
The push to amend the Imperial House Law reflects a critical demographic challenge facing the Japanese monarchy. Because current laws limit succession and membership, the pool of eligible royals is narrowing. These amendments likely aim to expand the number of people who can maintain royal status, potentially by allowing female members to remain in the family after marriage or expanding the definition of the imperial line.
