The Signature of Kofu Castle: Towering Walls of Irregular Boulders

The most impressive feature of Kofu Castle is the powerful stone walls that surround the entire castle. Built about 400 years ago, these walls remain in their original form.

The tallest stone walls exceed 14 meters, equivalent to a five-story building. Looking up, you will be overwhelmed by the sight of irregular boulders rising toward the sky.

These walls were built using a technique called nozurazumi (rough stone stacking). Natural stones were stacked with minimal processing, and smaller stones were packed into the gaps between larger ones. Unlike neatly arranged stone walls, these feature massive irregular boulders dramatically piled together.

Looking closely at the walls, you can find square holes arranged in rows on the stone surfaces.

These are called yaana (wedge holes). These holes were made to split large boulders, with wedges driven into them to break the stone apart.

The work of stonemasons from 400 years ago remains carved into these walls. While the powerful stone walls create an impressive scene, you can also glimpse the delicate craftsmanship of these artisans.

Restoration Progresses: Historic Structures Preserving the Past

Several lost structures have been restored at Kofu Castle. The gates and turrets rebuilt using period techniques are valuable assets that convey the history of the castle.

Kurogane Gate (Iron Gate)

Kurogane Gate is a two-story turret gate located at the boundary between the main bailey and the tower bailey. It was restored in 2013.

The name comes from the iron plates covering the gate doors. Covered with iron plates about 1 cm thick, the gate was built to withstand musket fire. It symbolizes the defensive capabilities of the castle.

Although separated from Maizuru Castle Park by the JR Chuo Main Line tracks, it has been developed as Kofu City History Park, adjacent to Koshu Yumekoji, a 5-minute walk from Kofu Station North Exit. It consists of two gates, the Korai Gate (Yamate Gate) and the turret gate (Yamate Watariyagura Gate), and you can view exhibits about Kofu Castle history inside the turret gate.

Mt. Fuji and Kofu Basin Views from the Tower Base

The main tower of Kofu Castle no longer exists, but you can climb to the tower base. The view from here is one of the greatest attractions of Kofu Castle.

From the tower base, you can enjoy a 360-degree view of the Kofu Basin. To the west, snow-capped peaks of the Southern Alps stretch across the horizon. To the north, the city center around Kofu Station spreads out below.

Looking south, Mt. Fuji rises beyond the cityscape of the Kofu Basin. On clear days, the snow-covered peak of Mt. Fuji stands out sharply. This view has been recognized as one of the 100 Views of Mt. Fuji from the Kanto Region.

About 160 Cherry Trees Adorning the Stone Walls

Kofu Castle is also known as a cherry blossom viewing spot. About 160 cherry trees are planted within the castle grounds, and in spring they bloom magnificently along the stone walls.

A Dry Landscape Japanese Garden Within the Castle

On the south side of Kofu Castle, a Japanese garden has been developed in the Kajikuruwa area. Created in 1993 in the karesansui (dry landscape) style, the garden features a dry stream of white sand at its center, surrounded by well-maintained greenery.

At the upstream end of the dry stream, a small dry waterfall rock arrangement has been placed, evoking the former inner moat and nearby rivers. This quiet garden showcases the contrast of white sand and green within a space enclosed by stone walls and white plaster.

History of Kofu Castle: A Strategic Stronghold Built by Toyotomi Hideyoshi

Kofu Castle was built after the fall of the Takeda clan in 1582.

In the 1590s, construction began under orders from Toyotomi Hideyoshi, who had unified Japan. The purpose was to keep Tokugawa Ieyasu, who held territory in the Kanto region, in check. Kai Province was a strategic point connecting the Tokaido and Nakasendo highways, making it an important military location.

Construction was overseen by Asano Nagamasa and his son Yukimasa, retainers of Hideyoshi. The castle is believed to have been completed around 1600.

After the Battle of Sekigahara in 1600, Kofu Castle became a Tokugawa castle. Kofu remained an important stronghold for the Edo shogunate, with castle lords closely connected to the shogunal family. In 1705, Yanagisawa Yoshiyasu, a chamberlain to the fifth shogun Tokugawa Tsunayoshi, became castle lord.

During the Meiji era, the buildings within the castle were demolished, but the stone walls survived and remain to this day. In 2019, it was designated a National Historic Site.

Stone Walls Underground at the Prefectural Office: The Relocated Inner Moat Walls

The Yamanashi Prefectural Office is a 5-minute walk from Kofu Castle. In 2010, during construction of a new facility next to the prefectural office, stone walls from Kofu Castle inner moat were discovered.

Today, the excavated inner moat stone walls have been relocated and restored in the basement level of the new building, the Yamanashi Prefectural Government Disaster Prevention Building, and are open to the public free of charge as the Kofu Castle Stone Wall Exhibition Room.

Which Entrance? Kofu Castle Has Five Entry Points

Choosing an entrance can be confusing on your first visit. Kofu Castle has five entrances, each with its own characteristics. Choose based on your purpose and mobility needs.

Map showing the five entrances to Kofu Castle with photos and route information
  1. Maizuru Castle Park Entrance
    The closest entrance from JR Kofu Station. It leads through the Inari Bailey with the Inari Turret to the main bailey where the tower base is located. This route has no stairs, only slopes, making it easy for families with strollers. The slopes are moderately steep, so wheelchair users will need assistance.
  2. Hydrangea Plaza Entrance
    This entrance is located beside the Hydrangea Plaza at the northeast corner of Kofu Castle. Except for the initial stairs, the entire route consists of slopes, also leading through the Inari Bailey to the main bailey. Convenient when coming to Kofu Castle from Koshu Yumekoji.
  3. Uchimatsukage Gate
    This is also one of the closest entrances from JR Kofu Station. Unlike the Maizuru Castle Park Entrance, this route uses stairs to climb directly to the main bailey. Convenient if you want to reach the main bailey by the shortest route.
  4. Kajikuruwa Gate
    This entrance is at the southwest corner of Kofu Castle. It is the longest route to the main bailey and tower base, with both slopes and stairs.
  5. Yukibashi Bridge
    An entrance on the south side of Kofu Castle. Cross the Yukibashi Bridge to enter the castle. Convenient when coming from Koedo Kofu Hanakoji.

For the most complete experience of Kofu Castle highlights, the route from Kajikuruwa Gate is recommended.
