岩崎城

Iwasaki Castle is a mountain stronghold on the summit of Mount Iwasaki with stone walls and earthen embankments spreading across multiple enclosures connected by narrow pathways. The fortress unfolds in layers, with each section designed to control movement and sightlines across the steep terrain.

The castle was founded by the Iwasaki Clan during the Namboku Period and became a focal point of territorial conflict between the Nambu and Date clans. Control of the stronghold shifted as these two powers competed for dominance across Mutsu Province.

Locals value this mountain stronghold as a connection to regional identity and a place of natural exploration. Visitors walking through the grounds experience how the fortification was built to blend with the surrounding landscape.

The walk to the castle site takes about 45 minutes on foot from Fujine Station on the Kitakami Line, with no entrance fee required. The paths are steep and narrow in places, so good footwear and attention to footing are important for a safe visit.

A preserved masugata gate in the third bailey connects to the main bailey through an ancient bridge structure designed to confuse and slow any approaching intruders. This geometric gate style was a clever defense tactic used by medieval Japanese castle builders.
