Descripción

Edo-period Japan had astronomers, too — but they worked under strict Tokugawa control. In this episode of Fexingo History, Lucas and Luna explore the hidden world of tengaku (Japanese astronomy) and rekidō (calendar science), tracing how the shogunate used the heavens to legitimize its rule and navigate a crisis: the Jōkyō calendar reform of 1684. We meet Shibukawa Harumi (also known as Yasui Santetsu), the astronomer-priest who challenged 800 years of Chinese almanac tradition; the Tokugawa bugyō who managed the official calendar bureau; and the shogun Tsunayoshi himself, who staked his authority on the reform. We also uncover the origins of the Japanese zodiac, the role of the Ise Grand Shrine in timekeeping, and the little-known story of a Buddhist monk who smuggled European astronomical tables into sakoku Japan. Along the way, we touch on how the calendar touched every life — from rice planting to festival days — and how Tokugawa control of the heavens meant control of the realm. #TokugawaShogunate #EdoPeriod #JapaneseAstronomy #ShibukawaHarumi #JōkyōCalendar #CalendarReform #Rekidō #Tengaku #YasuiSantetsu #TokugawaTsunayoshi #Sakoku #JapaneseHistory #EastAsia #HistoryOfScience #IseShrine #BuddhistAstronomy #FexingoHistory #History 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]

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

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]

Tokugawa Japan's Hidden Diplomats: The Korean Missions and the Shogun's Silk Road

In this episode, Lucas and Luna explore the Korean missions to Tokugawa Japan—the Chōsen Tsūshinshi. Between 1607 and 1811, twelve large diplomatic delegations traveled from Joseon Korea to Edo, bearing gifts, letters, and a delicate balance of power. These missions were more than etiquette: they were conduits for books, ceramics, medicine, and even firearms. Lucas traces the origins after the 1592-98 Imjin War, the negotiations by the Sō clan of Tsushima, and the changing reception as sakoku took hold. He highlights key figures like the scholar-official Yi Su-gwang, who exchanged knowledge with Japanese Confucians, and the 1719 mission that included the famed painter Kim Myeong-guk. The episode also covers the 1811 mission that never reached Edo—a sign of the shogunate's waning authority. Luna's questions draw out the human side: what Korean envoys thought of Japan's isolation, how they were treated in the provinces, and what cultural relics survive today. A rich look at a forgotten bridge between two insular worlds. #ChōsenTsūshinshi #JoseonKorea #TokugawaJapan #KoreanMissions #SōClan #Tsushima #YiSu-gwang #KimMyeong-guk #Sakoku #EdoPeriod #ImjinWar #Diplomacy #EastAsia #History #FexingoHistory #KoreanHistory #JapaneseHistory #CulturalExchange Keep every episode free: buymeacoffee.com/fexingo [https://buymeacoffee.com/fexingo]

Tokugawa Japan's Forgotten Pirates: The Murakami Fleet and the Battle of Itsukushima

When we think of Tokugawa Japan, we tend to imagine a land at peace, sealed off from the world. But long before the shoguns secured their grip, the seas around Japan were ruled by pirates. In this episode, Lucas and Luna explore the rise and fall of the Murakami family — the most powerful pirate clan of the Seto Inland Sea. They commanded hundreds of swift atakebune warships, controlled vital shipping lanes, and fought alongside legendary warlords like Mōri Motonari. At the Battle of Itsukushima in 1555, the Murakami fleet delivered a devastating surprise attack that helped shape the course of the Sengoku period. But as Tokugawa Ieyasu unified Japan and imposed sakoku, these once-indispensable sea lords faced a stark choice: dissolve into obscurity or become loyal coast guards for the new regime. Lucas traces the Murakamis' transformation from feared privateers to forgotten servants of the shogun, and reflects on how the Tokugawa peace rendered their kind obsolete. #TokugawaJapan #MurakamiPirates #SetoInlandSea #SengokuPeriod #BattleOfItsukushima #MōriMotonari #Atakebune #Sakoku #CoastDefense #EdoPeriod #Wakō #NavalHistory #JapaneseHistory #EastAsia #Piracy #FexingoHistory #HistoryPodcast #FeudalJapan Keep every episode free: buymeacoffee.com/fexingo [https://buymeacoffee.com/fexingo]
