Kunōzan Tōshō-gū (久能山東照宮)

Tokugawa Ieyasu died in 1616 at Sunpu Castle, and his body remained on Kunōzan for exactly one year before being moved to Nikkō. This coastal mountain in Shizuoka was his explicit choice — the place where his remains would face east toward Edo, protecting the city he had transformed into the shogunate capital. The shrine built over his first burial site is older than Nikkō’s famous Tōshō-gū by one year, and contains what many consider the finest early Edo lacquerwork in existence. While Nikkō became the public monument, Kunōzan remained the intimate original — 1,159 stone steps up a cliff overlooking Suruga Bay, where Ieyasu’s spirit was first enshrined as a god.

Kunōzan Tōshō-gū was established in 1617 by order of the second shogun, Tokugawa Hidetada, on the site where his father’s remains had rested for one year. Ieyasu had chosen this location himself before his death, instructing that he be buried here facing east. The mountain had been sacred since ancient times — a temple dedicated to Kannon had stood here since the Nara period. After Ieyasu’s deification as Tōshō Daigongen (Great Gongen Illuminating the East), construction began on a shrine that would serve as the architectural prototype for all later Tōshō-gū shrines. The main hall and worship hall were completed in just one year and seven months, employing the newly developed gongen-zukuri style that fused the two buildings with a stone-floored connecting chamber. In 1617, Ieyasu’s remains were ceremonially transferred to Nikkō, but his original burial site remained sacred, and the shrine became the head of all Tōshō-gū shrines nationwide in 2010.

Tokugawa Ieyasu, deified as Tōshō Daigongen (東照大権現), is the primary deity. He is worshipped as a protective kami of the nation, peace, and military victory. Ieyasu unified Japan after centuries of civil war and established the Tokugawa shogunate that would rule for 264 years. His deification transformed him from military leader into divine protector — a figure believed to guard Japan from the east, facing the rising sun. The name Tōshō (illuminating the east) reflects both his geographical position protecting Edo and his role as bringer of peace after the warring states period.

On his deathbed at Sunpu Castle, Ieyasu gave specific instructions: “Bury me on Kunōzan. After one year, build a small shrine at Nikkō. I will be the guardian deity of the Kanto.” His choice of Kunōzan was deliberate — from this cliff, he could watch over both Suruga Bay and the Tōkaidō road, the main artery connecting Kyoto to Edo. One year after his death, when his remains were exhumed for transfer to Nikkō, witnesses reported that his body showed no signs of decay — taken as proof of his divine transformation. The decision to move him to Nikkō was political (a grander monument closer to Edo), but many believed his spirit remained strongest here at Kunōzan, his chosen resting place. A legend persists that Ieyasu’s true remains were never moved, that the elaborate funeral procession to Nikkō was ceremonial, and his body still rests beneath Kunōzan’s innermost sanctuary.

The shrine is designated a National Treasure and represents the pinnacle of early Edo architecture. The main hall (honden) and worship hall (haiden) are connected by a stone-floored chamber (ishi-no-ma), creating the gongen-zukuri style that would be replicated at Nikkō and elsewhere. Every surface is covered in intricate lacquerwork and gilt decoration — 2,316 colored and gilded carvings depicting Chinese lions, phoenixes, dragons, and auspicious plants. The colors are more restrained than Nikkō’s later excess; the black lacquer backgrounds make the gold leaf shimmer rather than overwhelm. The yomeimon gate, though smaller than Nikkō’s famous version, contains equally refined carving. The shrine museum houses Ieyasu’s personal effects, including his armor, sword (a National Treasure), and the original portable shrine used in his deification ceremony. The approach is dramatic: 1,159 stone steps climb straight up the cliff face, or visitors can take a ropeway from Nihondaira plateau above.

• Tosho-gu Grand Festival (February 17) — Commemorates Ieyasu’s death with solemn rituals and offerings. Shinto priests perform ancient court music (gagaku) in the worship hall.
• Spring Grand Festival (April 17) — Celebrates Ieyasu’s deification anniversary with a procession of shrine maidens and ritual dances.
• Autumn Grand Festival (October 17) — Features demonstrations of mounted archery (yabusame) and traditional martial arts honoring Ieyasu’s military legacy.
• New Year’s Day Ceremony — The first sunrise of the year is particularly significant here, as devotees watch the sun rise over Suruga Bay from Ieyasu’s eastern vantage point.

Early morning in autumn (October-November) offers the clearest views across Suruga Bay to Mount Fuji. The climb up 1,159 steps is cooler before 9 AM, and the lacquerwork in the main hall catches the morning light at its richest. The autumn grand festival on October 17 includes martial arts demonstrations that connect directly to Ieyasu’s legacy. Cherry blossoms bloom in early April along the approach, though the focus here is architectural rather than seasonal. Winter (December-February) brings the best Fuji views but cold winds off the bay. Avoid the intense summer heat and humidity, which make the stone steps punishing. The shrine is never as crowded as Nikkō, giving space to appreciate the craftsmanship in relative quiet.
