Kozukappara Execution Grounds
The were one of the three sites in the vicinity of Edo (the forerunner of present-day Tokyo, Japan) where the Tokugawa shogunate executed criminals in the Edo period. Alternate romanized spellings are ''Kozukahara'' and ''Kotsukappara''. The site is located in modern Minami Senju, Arakawa, Tokyo, a three-minute walk away from Minami-Senju Station. Located next to Enmeiji Temple, a large part of the grounds are now covered by railway tracks. It is estimated that between 100,000 and 200,000 people were executed here. Those executed include Hashimoto Sanai and Yoshida Shōin, who were executed as a result of the Ansei Purge. Sugita Genpaku, Nakagawa Jun'an, Katsuragawa Hoshū and their colleagues studied anatomy by conducting dissections at Kozukappara. Kozukappara began operation in 1651, and continued until the Meiji period. Executions were stopped in an attempt to convince Western powers to end the unequal treaties with Japan.

Carl Peter Thunberg
Carl Peter Thunberg, also known as Karl Peter von Thunberg, Carl Pehr Thunberg, or Carl Per Thunberg (11 November 1743 – 8 August 1828), was a Swedish naturalist and an "apostle" of Carl Linnaeus. After studying under Linnaeus at Uppsala University, he spent seven years travelling in southern Africa and Asia, collecting and describing many plants and animals new to European science, and observing local cultures. He has been called "the father of South African botany", "pioneer of Occidental Medicine in Japan", and the "Japanese Linnaeus". Early life Thunberg was born and grew up in Jönköping, Sweden. At the age of 18, he entered Uppsala University where he was taught by Carl Linnaeus, regarded as the "father of modern taxonomy". Thunberg graduated in 1767 after 6 years of studying. To deepen his knowledge in botany, medicine and natural history, he was encouraged by Linnaeus in 1770 to travel to Paris and Amsterdam. In Amsterdam and Leiden Thunberg met the Dutch bota ...

As a member of one of the five samurai families supported by the Tokugawa shogunate as hereditary official Dutch translators, Kōsaku vetted imported documents (Christian materials were prohibited in Edo period Japan) and helped to keep the shogunate informed of global political matters. From roughly 1770 to 1800, he served as the chief mediator between the Dutch community on Dejima and the shogunate.Screech. p15.

Cryptanalysis
Cryptanalysis (from the Greek ''kryptós'', "hidden", and ''analýein'', "to analyze") refers to the process of analyzing information systems in order to understand hidden aspects of the systems. Cryptanalysis is used to breach cryptographic security systems and gain access to the contents of encrypted messages, even if the cryptographic key is unknown. In addition to mathematical analysis of cryptographic algorithms, cryptanalysis includes the study of side-channel attacks that do not target weaknesses in the cryptographic algorithms themselves, but instead exploit weaknesses in their implementation. Even though the goal has been the same, the methods and techniques of cryptanalysis have changed drastically through the history of cryptography, adapting to increasing cryptographic complexity, ranging from the pen-and-paper methods of the past, through machines like the British Bombes and Colossus computers at Bletchley Park in World War II, to the mathematically advanced ...

Shōgun
, officially , was the title of the military dictators of Japan during most of the period spanning from 1185 to 1868. Nominally appointed by the Emperor, shoguns were usually the de facto rulers of the country, though during part of the Kamakura period, shoguns were themselves figureheads, with real power in hands of the Shikken of the Hōjō clan. The office of shogun was in practice hereditary, though over the course of the history of Japan several different clans held the position. The title was originally held by military commanders during Heian period in the eighth and ninth centuries. When Minamoto no Yoritomo gained political ascendency over Japan in 1185, the title was revived to regularize his position, making him the first shogun in the usually understood sense. The shogun's officials were collectively referred to as the ; they were the ones who carried out the actual duties of administration, while the Imperial court retained only nominal authority.Beasley, Willi ...
