Mistakes

* In 1671, Japan had been consolidated under the Tokugawa bakufu for over 50 years, and the Samurai class had fallen out of the traditional service like that shown. Also, the only Europeans allowed near Japan were the Dutch, not the English, and were strictly monitored by the Japanese government. Takezo Kensei being an Englishman is very suspect. Also the Japanese (including bandits) used firearms and other gunpowder weaponry rather commonly by this point.
* In Brazil, people speak Portugese, not Spanish as is often mistaken.
* Claire's chemistry class seemingly out of nowhere speaks about Darwin, which has no connections to Chemistry but rather should be either in biology.
