Located northeast of Himeji Castle, this museum was established in April 1983 to deepen understanding of local history. Designed by renowned architect Kenzo Tange, its architecture echoes Himeji Castle’s aesthetics with white walls and stone-like facades. Reopened in 2007 and again in 2023 after major upgrades, its exhibitions span from ancient times to the modern era, covering the history of Hyogo Prefecture (the former provinces of Settsu, Harima, Tajima, Tamba, and Awaji). The museum holds a collection of over 200,000 items, including an Important Cultural Property — a Kamakura-period painting of the Buddha’s parinirvana — and five Prefectural Tangible Cultural Properties, alongside exhibits like the “Anatomy of Himeji Castle,” which displays the East Main Pillar of the castle’s keep and shachihoko roof ornaments restored during the Showa-era renovation.

The Nozato Gate Ruins mark the former northern entrance to Himeji Castle’s inner castle town. The gate is said to take its name from the adjacent Nozato-machi, a district known for its metalworking artisans, and the surrounding area is believed to have functioned as a town district even before Toyotomi Hideyoshi’s 1581 renovations. Strategically positioned along the Tajima Kaido highway, it featured a complex zigzag design with two double-doored gateways separated by an inner courtyard — the larger inner gate, facing north, was topped with a storehouse, while the east-facing outer gate stood at a right angle to thwart direct assaults.

The Nakabori, or Middle Moat, was an integral part of Himeji Castle’s triple-moat defense system, alongside the inner (uchibori) and outer (sotobori) moats. Constructed in the early 17th century under Ikeda Terumasa, it extended approximately 4.3 kilometers around the castle’s core structures. This northern stretch, near Nozato Gate, is one of several surviving segments that give visitors a sense of the moat’s former scale; only the moat’s southern stretch was filled in, for the construction of National Route 2 (completed 1932), so the moat as a whole was not entirely lost.

Himeji Jinja is a Shinto shrine adjacent to the castle grounds, established in 1879 (Meiji 12) by former retainers and prominent townspeople of Himeji Domain to honor Sakai Masachika, founder of the Sakai clan, who served as the domain’s last feudal lords. In 1927 (Showa 2) it was relocated to its current site in the northeastern part of the castle grounds, an area traditionally considered to ward off evil spirits. Within its precincts stand the Sunno Shrine, dedicated to Kawai Sunno, a notable figure in the domain’s development, and the Iwakura Inari Shrine, dedicated to the deity Ukanomitama.

The North Segakushi Gate Ruins mark a former northern entrance to the castle’s inner compounds, now within Himeyama Park. “Segakushi” refers to a concealed or hidden area, indicating the gate’s role as a discreet access point within the castle’s broader defensive network. While the original structure no longer exists, remnants of the stone walls remain.

Segakushi Bailey is a narrow, elongated area on the northern side of the Main Keep, designed as a defensive buffer to impede direct access to the central compound. Flanked by earthworks and moats, it was accessible through the North and South Segakushi Gates. Today the area is part of Himeyama Park, especially picturesque during cherry blossom and autumn foliage seasons.

Sagi-no-Shimizu, or “Heron’s Spring,” is a historic well recognized as one of the “Harima Jūsui” (Ten Famous Waters of Harima), esteemed for its pure water since the Muromachi period. The water was reputedly used in tea ceremonies; because of its location within the castle, commoners were barred from direct access and instead drew from the spring where it flowed into the nearby Semba River. The well features a stone-lined outer structure roughly 2.8 by 6 meters and 2.5 meters deep, with a wooden-framed inner well 1.3 meters in diameter at its center.

Shimizu Gate, meaning “Pure Water Gate,” was a gate in the castle’s middle moat and one of its key entrances, named for the nearby Sagi-no-Shimizu spring that supplied adjacent reservoirs and wells. Located along the Senba River, its architecture featured an outer west-facing koraimon gate leading into an inner courtyard, followed by a larger south-facing inner gate topped with a watchtower — a layout forcing attackers to slow down and change direction. A guardhouse stood just beyond the inner gate to monitor access.

Perched atop the 57.5-meter-high Otokoyama hill, this park offers one of the most breathtaking panoramic views of Himeji Castle, reached via a climb of roughly 198 steps that rewards visitors with a view of the main keep and its three smaller towers together. The park is also home to Otokoyama Hachimangū Shrine, dedicated to the castle’s guardian deity, and is recognized as one of the “Ten Scenic Views of Himeji Castle” — popular with photographers, especially at sunrise, sunset, and when the castle is illuminated at night.

Perched on the slopes of Otokoyama northwest of the castle, this modest shrine was established in 1623 by Princess Senhime, granddaughter of Tokugawa Ieyasu, and dedicated to Tenman Daijizai Tenjin (Sugawara no Michizane), reflecting her faith and hopes for her family’s prosperity. After remarrying Honda Tadatoki and moving to Himeji Castle, Senhime is traditionally believed to have commissioned the shrine so she could offer prayers from the castle’s Nishi-no-Maru, with the shrine’s orientation allowing direct line-of-sight worship. The current structure, rebuilt in 2002, features elegant karahafu (curved gable) architecture.

Sengoku no Komichi, or “Princess Sen’s Path,” is a picturesque walking trail between the western inner moat and the Semba River, running north to south alongside Himeji Castle. Lined with cherry blossoms and maple trees, it honors Princess Sen (Senhime), the granddaughter of Tokugawa Ieyasu who spent part of her life at Himeji Castle. While the path itself is a modern addition, it complements the historical ambiance of the castle grounds.

Ichinohashi Gate, meaning “Market Bridge Gate,” once served as a crucial western entrance connecting the castle grounds to the merchant and artisan districts across the Semba River. Its complex defensive design featured an outer gate facing west with a structure protruding over the moat, leading into an inner courtyard, then an inner gate set at an angle — a layout meant to slow down and expose attackers. A storehouse stood above the inner gate, with a guardhouse just beyond it.

This bronze statue of Princess Sen stands near Himeji Castle, commemorating her role in the castle’s history. As the granddaughter of Tokugawa Ieyasu and wife of Honda Tadatoki, lord of Himeji Castle, Senhime’s life was marked by both privilege and tragedy — after surviving the fall of Osaka Castle, she remarried and moved to Himeji, becoming deeply involved in the domain’s cultural and social affairs. The statue faces the direction of Otokoyama and Senhime Tenmangū Shrine, where she is believed to have prayed, and stands near the Ichinohashi Gate ruins, aligned with the Nishinomaru Hyakken Rōka.

Kōkoen Garden is a meticulously designed Japanese garden on the former site of Himeji Castle’s western residence (Nishi O-yashiki). Opened in 1992 to mark the 100th anniversary of Himeji’s incorporation as a city, it spans 3.5 hectares and comprises nine distinct gardens arranged in a traditional kaiyū-shiki (strolling-style) layout, conveying the atmosphere of the old castle town and samurai aesthetics. The garden’s name is said to derive from either Meiji-era military leader Kawai Yoshifuru, a descendant of a Himeji retainer, or from a phrase meaning “to cherish the past” — and also honors “Kōko-dō,” a provincial school established by the Sakai clan in 1692. The design incorporates tea gardens, pond-centered stroll gardens, and miniature mountains with forest streams, creatively framing views of Himeji Castle’s white walls and stone foundations.

Karo Yashiki Ato Park — literally “Site of the Chief Retainers’ Residences” — is a small history park just southwest of Himeji Castle, right next to Kōkoen Garden, on the former grounds of the mansions belonging to the domain’s karō: the most senior samurai retainers, who administered Himeji Domain on the lord’s behalf. During the Edo period, homes for these high-ranking vassals spread out beyond the castle walls, a reminder that the castle’s administrative and ceremonial life extended well into the surrounding castle town. Archaeological excavations have uncovered and partly restored sections of the original earthen walls, gate foundations, and stone-lined property boundaries.

The South Segakushi Gate, once a vital component of the castle’s intricate defensive network, now exists only in remnants — one of numerous gates designed to confuse and slow down potential invaders. Visitors can observe stone foundations that hint at its past significance, with informational signage providing historical context.

Kuruma Gate (“Carriage Gate”) was a significant western entrance positioned along the Semba River and the historic Saigoku Kaidō highway, reflecting its role in transporting vehicles and materials into the castle. It featured a double-masugata design: an outer gate facing west, a middle gate facing south, and a larger inner gate topped with a watchtower — a layout that slowed and exposed anyone passing through. Some accounts describe a removable wooden bridge over the moat and a waterside boat landing from the Semba River, though these details remain unconfirmed.

Uzumi Gate, meaning “Buried Gate,” was one of the gates set into Himeji Castle’s middle moat, on the southwestern side of the castle, said to have been added some years after Ikeda Terumasa’s main expansion by cutting an opening into an existing stone wall (hence its name) — though the exact construction date is not firmly established. Unlike other gates, it lacked a watchtower directly above it — instead, a two-story turret and guard station stood just west of the gate, overseeing the southwestern corner of the castle and the Saigoku Kaidō highway. The gate featured both an outer and inner gate, both facing south, with a soil bridge over the inner moat.

Kumataka-mon, named after the mountain hawk-eagle (kumataka), once stood as a significant entry point within the castle’s defensive network — one theory suggests the castle’s lord kept hunting birds nearby, linking the gate to the raptor, though the exact reason for the name remains uncertain. Only the stone foundations remain today. Notably, the earth-and-stone bridge in front of the gate functioned like a dam, helping regulate the moat’s water level by allowing water to spill over and raise the level on its other side.

Nakanomon, or “Middle Gate,” once stood along the southern approach to Himeji Castle, a key checkpoint between the outer defenses and the castle proper, near the old Saigoku Highway. At night the gate was closed to the general public, with only physicians granted emergency access after sundown. An official noticeboard near the gate posted domain-wide proclamations for residents, making the area a hub of civic communication as well as a physical gateway.

This southern stretch of the Nakabori (Middle Moat) encircled the Ninomaru (Second Bailey), forming part of the castle’s triple-moat defense system and protecting the samurai residences and administrative areas within. Constructed in the early 17th century under Ikeda Terumasa, this southern stretch of the moat was filled in when National Route 2 was built over its path (completed 1932) — only this southern portion was lost, not the moat as a whole — though sections and accompanying earthworks remain visible along walking paths that trace its original course.

Sōja Gate was one of five main gates on the southern side of the castle’s Naka-kuruwa (Middle Bailey), named for its proximity to the west gate of Harima Sōja Shrine just northeast of the gate. Built in the early 17th century under Ikeda Terumasa, it featured a masugata design with an outer gate facing south and an inner gate facing east, trapping attackers in crossfire from multiple angles; a guardhouse nearby monitored those entering and exiting the castle.
