# Japanese Cartoonist Challenges Revised Imperial Succession Law

A Japanese cartoonist has launched a court challenge against the government over its revised imperial succession law, which allows male-only heirs to inherit the throne.

The artist, known for writing books on history and monarchy, is contesting the law's discriminatory rules, which prioritize male relatives in the adoption process. The revised legislation, which came into effect on Saturday, has been met with criticism from those who argue it perpetuates a patriarchal system within Japan's 1,500-year-old monarchy.

Next in line to inherit the throne after Emperor Naruhito is his younger brother Akishino, followed by Prince Hisahito, a 20-year-old nephew. However, there are no other eligible heirs in this generation, which has sparked debate over the future of the imperial succession.

The revised law permits unmarried male descendants aged 15 or older from former branch families to be adopted into the royal family through an unbroken male line, but critics argue that these relatives are too distant to be considered true kin. Four out of 11 former branch families who renounced their royal status in 1947 remain eligible for adoption under this new rule.

Yoshinori Kobayashi's lawsuit against Japan's new imperial succession law is based on his claim that it discriminates against commoners by allowing former royals to adopt into the royal family while excluding other commoners from doing so.

According to Article 14 of the Japanese constitution, all citizens are entitled to equality regardless of their "race, creed, sex, social status or family origin". Kobayashi argues that this provision is being undermined by the adoption system in the revised law, which he believes will create a new class system in Japan.

The lawsuit was filed with the Tokyo District Court, marking the first legal challenge to the revised law. A trial date has not yet been set, but Kobayashi's comments suggest that he expects strong opposition from those who support the new succession rules.

Kobayashi's criticism of the law centers on its failure to confer royal status on the husbands and children of princesses who marry commoners, effectively excluding them from the line of succession. This has led him to dub it the "Aiko-sama exclusion law", in reference to Princess Aiko, who is currently unable to succeed her father due to the male-only succession policy.

The lawsuit filed by Kobayashi has brought attention to the concerns raised by legal experts regarding the adoption system's constitutionality. Government panel members on the imperial succession have expressed similar reservations about the law's validity.

Kobayashi's lawyer, Rintaro Kuramochi, acknowledges that winning the case would be challenging due to Japan's lack of a constitutional court and its current government's stance on the issue. The lawsuit aims to bring attention to the problem through this legal avenue, given the limited options available in the country.

The manga artist is seeking 1 million yen ($6,350) in damages for psychological suffering caused by the law, which undermines his commitment to democratic values such as equality and justice.
