The John & Yoko Phenomenon
from POST-WHATEVER with Ken Nishikawa · host Ken Nishikawa
Why is it almost always western man, Japanese woman — and the other way round is comparatively few? And why has it been that way since at least 1600?In this episode, Ken Nishikawa voluntarily marches into the minefield of race to examine the John & Yoko Phenomenon — the curious and persistent pattern of western men and Japanese women finding and gravitating towards each other across centuries, oceans, and apparently 47,000 years of genetic memory.Along the way: the first Englishman in Japan who navigated his way directly into prison; Hollywood's very convenient double standard on interracial romance; a brief detour into lion-tiger cross-breeding (for scientific reasons); and the shocking finding of Neanderthal — which rather undermines my potentially revolutionary hypothesis.No conclusions are reached. Several hypotheses collapse under their own weight. A good time is had.Post-Whatever with Ken Nishikawa — because someone has to ask the awkward questions.Sources & further reading:NEANDERTHAL / SCIENCE SOURCESThe sex-biased interbreeding study (the core science of the episode):https://www.science.org/doi/10.1126/science.aea6774The 47,000-year dating / Princeton study overview:https://www.sciencedaily.com/releases/2025/07/250713032519.htmWILLIAM ADAMS / MIURA ANJIN:https://en.wikipedia.org/wiki/William_Adams_(sailor)SESSUE HAYAKAWA https://en.wikipedia.org/wiki/Sessue_HayakawaTHE HAYS CODE / PRODUCTION CODE https://en.wikipedia.org/wiki/Hays_CodeFILMS MENTIONEDSayonara (1957): https://www.imdb.com/title/tt0050994/The Barbarian and the Geisha (1958): https://www.imdb.com/title/tt0051378/You Only Live Twice (1967): https://www.imdb.com/title/tt0062512/#PostWhatever #KenNishikawa #JapanUK #TokyoLife #ExpatJapan #JapanPodcast #TokyoPodcast#JohnAndYoko #JapanAndTheWest #InterracialCouples #MixedCouples #ExpatJapan #WesternManJapaneseWoman #CulturalDifferences #JapanCulture #TokyoLife #SoftPower #Neanderthal #HumanEvolution #DNA #PopularScience #Japan #Tokyo #Shimokitazawa #JapanExpat #JapaneseHistory #WilliamAdams #Shogun #JohnLennon #YokoOno #NicolasCage#JapanExpat #LivinginJapan #TokyoExpat #JapanTips #JapanLife #JapanVlog #TokyoVlog#JapanCulture #JapanBritain #JapanvsUK #CulturalDifferences #JapanObsessed #LearnAboutJapan #DryHumour #BritishHumour #Comedy #CulturalCommentary #Observational#Japan #Tokyo #Podcast #TalkShow #WeeklyPodcast #CulturePodcast
