This is a netnographical study of tweets about Princess Mako of Japan, who married in 2021. It aims to decode covert messages embedded in the negative tweets directed at her to uncover the sentiments Twitter users knowingly or unknowingly propagated.

Princess Mako of Akishino, a niece of the reigning Japanese Emperor Naruhito, encountered substantial adversity when her intention to marry Kei Komuro, her long-time boyfriend, shook the trust between the imperial family and the public. What started as a story of her personal milestone slowly evolved into a political crisis, questioning the raison d'être of the imperial family and becoming a bizarre, twisted dark comedy that nobody expected. In conjunction with national media outlets, social media platforms constructed an image of her “unofficial fiancé” as the quintessential villain and characterized him as a “tax thief,” undeserving of the princess.

On October 26, 2021, the day Princess Mako and Kei Komuro announced their marriage, 5,852 tweets with hashtags in five different categories appeared on Twitter. These hashtags can be classified into two main categories, all of which refer to Princess Mako. Two hashtags include honorifics— “sama”—which are used to show respect to people of higher standing, and they can be further divided into two subcategories with “sama” (様) being more formal than “sama” (さま). The other three hashtags are names without honorifics, including the following variations: Mako, Mako of Akishino, or her new married name, Mako Komuro. Among the 5852 tweets posted on the day of their marriage, 1,965 tweets were used for this research.

本数据集围绕2021年成婚的日本真子公主的相关推文展开网络民族志（netnography）研究，旨在解码针对她的负面推文中嵌入的隐蔽信息，以揭示Twitter用户有意或无意传播的情绪倾向。

秋筱宫真子公主是日本现任天皇德仁的侄女，当其与长期男友小室圭的结婚计划动摇了皇室与民众间的信任基础时，她遭遇了大量非议与严峻困境。这场原本属于个人人生里程碑的喜事，逐渐演变为一场政治危机：不仅引发了对日本皇室存续合理性的质疑，更最终成为一场无人预料的荒诞扭曲的黑色喜剧。配合国家媒体的叙事，社交媒体将她的"准未婚夫"塑造成了典型的反派形象，将其污蔑为"税务窃贼"，称其不配迎娶公主。

2021年10月26日，即真子公主与小室圭宣布结婚当日，Twitter上共出现5852条带有5类话题标签（hashtag）的推文。这些话题标签可分为两大类别，均指代真子公主。其中两个标签包含敬语“sama”，可进一步细分为两个子类别：“sama（様）”的正式程度高于“sama（さま）”。其余三个标签未使用敬语，涵盖的称呼变体包括：真子、秋筱宫真子，以及她婚后的新姓名小室真子。在当日发布的5852条推文中，共有1965条被用于本项研究。
