Tokugawa Japan's Forgotten Astronomer: Shibukawa Shunkai

Tokugawa Japan's Hidden Debt: The Rise of the Daimyo Loan Sharks

We've talked about the shogun's gold and the rice economy of Osaka, but what about the shadowy world of daimyo debt? In this episode, Lucas and Luna explore how Japan's feudal lords became trapped in a cycle of borrowing from wealthy merchants—especially the House of Mitsui and the Kōnoike family. We trace the origins of the daimyo loan system, the role of sankin kōtai in draining domain coffers, and the rise of merchant houses who grew richer than the samurai they served. We also look at Mizuno Tadakuni's disastrous Tenpō Reforms and how debt led to the fall of the Shimazu clan's finances—a prelude to the Meiji Restoration. Full of specific names, dates, and sums of gold ryō, this episode reveals the economic underbelly of the Pax Tokugawa. #TokugawaJapan #DaimyoLoans #Mitsui #Konoike #SankinKotai #MizunoTadakuni #TenpoReforms #ShimazuClan #OsakaMerchants #EdoEconomy #SamuraiDebt #RyoCurrency #MeijiRestoration #JapaneseHistory #EdoPeriod #FexingoHistory #HiddenPower #History Keep every episode free: buymeacoffee.com/fexingo [https://buymeacoffee.com/fexingo]

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]
