Goryokaku Half Moon Fort

Where the samurai era made its last stand

Goryokaku was built for the defence of the north, but it is remembered for a civil war rather than a foreign one. At the centre of the fort stood the Hakodate Magistrate's Office, the administrative headquarters from which shogunate officials governed Hokkaido. After the shogunate returned power to the emperor in 1867, die-hard loyalists refused to accept defeat. A fleet under Enomoto Takeaki sailed north, seized the largely undefended fort in late 1868, and proclaimed a short-lived provisional government in Ezo.↗↗↗

The resulting Battle of Hakodate became the final act of the Boshin War. In May 1869 New Government forces, including warships pounding the fort from the harbour, overwhelmed the shogunate troops. It was during this fighting that Hijikata Toshizo, the famed vice-commander of the Shinsengumi, was fatally shot near the city's Cross-Point district—a moment that has made Goryokaku a pilgrimage site for fans of Bakumatsu history, films and the manga Golden Kamui. Defeat here marked the true start of the Meiji era; the Magistrate's Office was dismantled in 1871, and the grounds opened as a public park in 1914.↗↗↗↗

See the star from Goryokaku Tower

Walking the earthworks gives you tunnels of trees, water and sky—but the fort's defining geometry is invisible from inside it. The payoff comes from the adjacent Goryokaku Tower, a 107-metre observation tower (the second, opened in 2006) whose glass-walled deck sits about 90 metres above the ground. From here the perfect five-pointed star unfolds beneath you, framed in spring by a sea of pale pink blossom and ringed by the surrounding city.↗↗↗

The 360-degree windows sweep past the fort to Mt. Hakodate and the harbour on one side and the whole city on the other. Up top you'll also find a seated statue of Hijikata Toshizo and exhibits that lay out the fort's history—best viewed before you descend, so the ground-level stroll reads with far more meaning.↗↗

The reconstructed Magistrate's Office

Back inside the star, the centrepiece is the Hakodate Magistrate's Office, faithfully rebuilt on its original footprint and reopened in 2010 using traditional methods and premium materials—earth plaster, hinoki cypress and some 38,000 hand-made tiles reproducing the roof ornament seen in old photographs. About a third of the vast original complex was reconstructed, so you can walk through tatami-floored great rooms, including a 72-tatami hall of four joined chambers, and get a true feel for shogunate craftsmanship and scale.↗↗↗↗

The building also houses rooms of artefacts and displays on the Bakumatsu period and the Battle of Hakodate. It is the only structure-type attraction here with its own admission fee, and a quiet indoor stop worth pairing with the open-air walk.↗↗

Cherry blossoms and four-season walks

From the 1950s onward, thousands of Yoshino cherries were planted along the moats and banks, and today roughly 1,500–1,600 trees make Goryokaku one of Hokkaido's finest hanami spots. Peak bloom usually falls in late April to early May—later than most of Japan—when petals drift onto the water and tint the moat pink. During the season you can row a hand-paddle boat along the moat beneath the blossoms, stroll the paths, and at night watch the trees lit up; in designated areas locals hold Hakodate-style hanami with jingisukan lamb barbecue.↗↗↗↗

The park rewards a visit in every season: fresh green over the ramparts in summer, vivid maple and cherry colour in autumn, and a hushed snow scene in winter, when frozen moats mirror the trees and the roughly 1.8-kilometre outer walking loop invites a slow circuit. Even after the cherries fade, there are wisteria trellises past Ninohashi bridge, azaleas along the banks, and red-and-white water lilies near the rear gate.↗↗↗

In deep winter, the fort glows again: the "Hoko no Yume" illumination strings around 2,000 bulbs to trace the star-shape above the moats after dusk (typically early December to late February), a scene that reads most magically from the tower's observation deck.↗↗

Festivals and living history

Goryokaku's grounds double as a stage for Hakodate's dramatic past. Each May the Hakodate Goryokaku Festival recreates the Bakumatsu era with performances on a special stage set inside the fort, including cannon and rifle displays and swordplay, while the summer Hakodate Outdoor Historical Drama casts local citizens to reenact the city's turbulent history—Ainu era, trading ships, the opening of the port, the Battle of Hakodate and great fires—against the earthworks themselves.↗↗
