Kininarunote
This is a small English pilot of Kininarunote, a Japanese site where the writer looks into things they got curious about and writes up what they found. This section carries only a handful of articles, translated and adapted from the Japanese originals. The rest of the site is in Japanese — see the full Japanese site.
These articles are localized from Japanese source articles, not written from scratch in English. The facts, numbers, and sources are the same as the Japanese original; only the wording and a few culture-specific explanations have been adapted for readers who did not grow up in Japan. Each article links back to its Japanese source.
