The Shogun's Missing Treasure: Tokugawa Japan's Lost Gold

Tokugawa Japan's Forgotten Astronomer: Shibukawa Shunkai

In 1684, Japan adopted a new calendar, the Jōkyō-reki, the first ever created by Japanese astronomers rather than imported from China or Korea. This episode tells the story of Shibukawa Shunkai (also known as Yasui Santetsu), the samurai-turned-astronomer who made it possible. Born into a Kyoto family of go players, Shunkai taught himself mathematics and astronomy from Jesuit books smuggled through Nagasaki, then used his observations of lunar eclipses to correct centuries-old errors in the lunisolar calendar. His work challenged the authority of the Imperial court's traditional calendar-keepers and sparked a quiet revolution in Japanese science. We explore how the Tokugawa shogunate, despite its isolationist policies, quietly relied on Western astronomical techniques, and how Shunkai's legacy paved the way for later rangaku scholars like Sugita Genpaku. A story of curiosity, precision, and the slow arrival of modern science in Edo Japan. #ShibukawaShunkai #Jōkyōreki #EdoAstronomy #JapaneseCalendar #TokugawaJapan #Rangaku #YasuiSantetsu #Nagasaki #LunarEclipse #LunisolarCalendar #HistoryOfScience #EdoPeriod #Sakoku #JesuitScience #Shōgun #Kyoto #History #FexingoHistory Keep every episode free: buymeacoffee.com/fexingo [https://buymeacoffee.com/fexingo]

Tokugawa Japan's Forged Identity: The Impersonation of Toyotomi Hideyori

In 1615, the Tokugawa shogunate crushed the Toyotomi clan at the Siege of Osaka, seemingly ending all threats. But decades later, a mysterious man claiming to be Toyotomi Hideyori—the son of the great unifier, supposedly killed in the flames—surfaced in Kyoto, rallying ronin and challenging Tokugawa legitimacy. This episode unravels the strange case of the Hideyori impersonator, the shogunate's ruthless response, and what it reveals about the fragility of Tokugawa power. Lucas and Luna explore how the bakufu used surveillance, propaganda, and brutal punishment to stamp out any spark of Toyotomi revival, and why even a ghost of the past could unsettle a regime that had ruled for decades. The story touches on the Ōkubo Nagayasu affair, the role of onmitsu spies, and the lasting cultural memory of the Toyotomi clan in Edo-period Japan. #Tokugawa #ToyotomiHideyori #SiegeOfOsaka #Impersonation #EdoPeriod #Bakufu #Onmitsu #Ronin #Kyoto #ŌkuboNagayasu #Shogunate #Legitimacy #Rebellion #JapanHistory #TokugawaHidetada #History #FexingoHistory #EastAsianHistory Keep every episode free: buymeacoffee.com/fexingo [https://buymeacoffee.com/fexingo]

Tokugawa Japan's Forgotten Shipwrecks: The Ise Jinkichi Incident

In 1647, a Japanese treasure ship bound for Nagasaki was wrecked off the coast of Taiwan. Its captain, Ise Jinkichi, was rescued by Dutch traders and eventually returned to Edo — but the shogunate's response reveals the paranoia and isolationism of early sakoku. This episode explores the little-known story of the 'Jinkichi Incident', the shogunate's crackdown on foreign travel, and the fate of Japanese castaways who washed up on foreign shores. Lucas and Luna discuss the Tokugawa policy of 'kaikin' (maritime prohibitions), the role of Chinese smugglers, and the legend of a cursed ship. A deep dive into Edo's fear of the outside world. #TokugawaJapan #Sakoku #EdoPeriod #IseJinkichi #Taiwan #DutchEastIndiaCompany #Nagasaki #Kaikin #Castaways #Shipwrecks #17thCentury #JapanHistory #NagasakiBugyō #Deshima #ChineseSmugglers #MaritimeHistory #FexingoHistory #History Keep every episode free: buymeacoffee.com/fexingo [https://buymeacoffee.com/fexingo]

Tokugawa Japan's Secret Religion: The Syncretic Faith of the Kakure Kirishitan

In this episode of Tokugawa Japan: Peace, Isolation, and Hidden Power, Lucas and Luna explore the hidden world of the Kakure Kirishitan—Japan's secret Christians who practiced their faith in hiding for over two centuries after the Shimabara Rebellion. Discover how they adapted Catholic rituals into a Japanese framework, mixing Buddhist and Shinto elements to create a unique syncretic religion. Learn about the 'fumi-e' ceremony, the role of the 'metsuke' in rooting out believers, and the isolated communities on the Goto Islands where oral traditions and hidden icons (Maria Kannon) survived. We also look at the 'Bateren' expulsion and the 'Sakoku' policy that drove Christianity underground. How did the Kakure Kirishitan preserve their faith without priests or scriptures? And what happened when Japan reopened in the 19th century? Join us for a fascinating look at resilience, secrecy, and cultural fusion. #KakureKirishitan #HiddenChristians #TokugawaJapan #EdoPeriod #ChristianityInJapan #ShimabaraRebellion #FumiE #MariaKannon #Nagasaki #GotoIslands #Sakoku #Syncretism #ReligiousPersecution #Bateren #Metsuke #JapaneseHistory #History #FexingoHistory Keep every episode free: buymeacoffee.com/fexingo [https://buymeacoffee.com/fexingo]

The Shogun's Whales: Tokugawa Japan's Forgotten Coastal Industry

When we think of Tokugawa Japan, we picture samurai, rice taxes, and sakoku isolation. But along the coasts of Ise, Kishū, and Tosa, a brutal and lucrative industry flourished: whaling. In this episode, Lucas and Luna dive into the world of the isami-gumi — the whaling guilds that operated under daimyo patronage. They explore the evolution of whaling from drift-whaling to organized net-and-harpoon hunts, the role of the Wada family in Kishū, the use of whale oil for lamps and agriculture, and the strange intersection of whaling with foreign relations — including how stranded American whalers became a crack in sakoku. They also discuss the environmental and social costs, from overhunting to the dangerous lives of the whalers. For listeners who know the samurai and the shoguns, this episode uncovers a hidden layer of Tokugawa economy and coastal life. #TokugawaJapan #EdoPeriod #Whaling #IsamiGumi #WadaFamily #Kishū #Tosa #Ise #Sakoku #WhaleOil #JapaneseHistory #CoastalIndustry #Daimyo #MobyDick #Ecology #History #FexingoHistory #MaritimeHistory Keep every episode free: buymeacoffee.com/fexingo [https://buymeacoffee.com/fexingo]
