Kodokan

**What to focus on:** The Shōgakudō (main lecture hall) retains original wooden desks and alcove scrolls. The Bujutsu-dokoro (martial training hall) displays Edo-period training weapons — real swords, yari (spears), and early artillery pieces that samurai students used. The archery range in the rear courtyard is rarely mentioned in guides but offers the most intact original architecture. **Archive highlights:** Request access to the Shōkōkan archives (free, open weekdays 10:00–16:00) to view Edo-period documents and woodblock-printed texts. The archivists speak limited English but can show key items upon request — look for Aizawa Seishisai's 'Shinron' (New Theses, 1825), one of the earliest nationalist political texts in Japan. **Historical context:** Kodokan was not just a school but a political laboratory. The Mito School's philosophy — sonnō jōi (revere the emperor, expel the barbarians) — directly challenged Tokugawa authority while ostensibly supporting it. Many students became key Meiji Restoration leaders. Understanding this contradiction deepens appreciation of the site. **Combine with:** Tokiwa Shrine (5-min walk) enshrines Tokugawa Mitsukuni and Nariaki. The shrine's treasure hall displays personal artifacts including Nariaki's armor and calligraphy.
