Tamanawa Castle Visiting Hours, Tickets, and Kamakura Historical Sites Guide

Date: 04/07/2025

Introduction

Tamanawa Castle (玉縄城, Tamanawa-jō), nestled in Kamakura, Japan, is a significant historical site that embodies the region’s samurai legacy and Sengoku period fortification techniques. Established in 1512 by Hōjō Sōun, the founder of the Later Hōjō clan, Tamanawa Castle was built to control critical routes connecting the Kamakura basin and Miura Peninsula. Unlike the imposing stone castles of later periods, Tamanawa Castle exemplifies the yamajiro (mountain castle) style, making strategic use of natural terrain, earthworks, moats, and wooden defenses.

Although much of the original structure has been lost to time and urban development, the ruins, interpretive signage, and the adjacent Tamanawa History Museum provide visitors with a comprehensive understanding of the castle’s historical and cultural importance. This guide details the site’s history, architectural features, role in regional conflicts, practical visiting information, and recommendations for making the most of your trip to Kamakura’s historical landscape.

Early Foundations and Strategic Importance

Tamanawa Castle’s construction marked a turning point for the Hōjō clan, establishing a stronghold at a vital crossroads in the Kanto region. Its location allowed the Hōjō to monitor and defend against rival clans, including the Uesugi and Satomi, during the tumultuous Sengoku period. The castle’s position was both militarily strategic and symbolic of the Hōjō’s growing power (kamakuraguide.com).

Architectural Features and Defensive Innovations

Designed as a classic yamajiro, Tamanawa Castle utilized steep slopes, multiple baileys, dry moats, and high earthen ramparts. The main bailey, or honmaru, crowned the site’s highest point and was surrounded by a network of terraced enclosures and moats, maximizing the castle’s defensive capabilities. Archaeological surveys continue to reveal details about these military innovations (kamakuramap.com).

Role in Regional Conflicts

Throughout the 16th century, Tamanawa Castle played a vital role in the era’s regional power struggles. It served as a command center and defensive outpost for the Hōjō clan, withstanding sieges and attacks, most notably the 1590 siege by Toyotomi Hideyoshi’s forces. The castle’s eventual surrender marked the end of Hōjō dominance and ushered in a new era under Toyotomi and, later, Tokugawa rule.

Decline, Abandonment, and Cultural Significance

After the Hōjō defeat, the castle briefly served the Tokugawa before it was decommissioned in the early 17th century. Over time, the structure was dismantled and the site reclaimed by nature. Despite this, Tamanawa Castle remains a valuable resource for understanding Sengoku-period defensive architecture and the social order of samurai society (kamakuraguide.com). Local preservation efforts and interpretive signage allow visitors to engage with the site’s layered history (kamakuramap.com).
