[Aizu Historical Exploration] The mountain that 13-year-old boys bravely challenged ── The story of Hoyoji Temple and the Shugendo of Mount Iide


福島県会津美里町・雀林にある、法用寺(ほうようじ)。 その山門をくぐると、深い時間の気配が立ち上がってきます。 ここはかつて、霊峰・飯豊山(いいでさん)を統括する「別当寺」として、修験者たちが集まる巨大な拠点でした。そして、毎年夏──13歳になった少年たちが、命懸けの修行のためにこの境内に集まりました。

Suzurin, Aizumisato Town, Onuma District, Fukushima Prefecture. Quietly nestled among the fields in the southwest of the Aizu Basin, the temple stands.

In the precincts, a rare three-story pagoda in Tohoku quietly stands tall, and the main hall and Kannon hall retain their ancient appearance.

This is Hōyō-ji. It is a Tendai sect temple, one of the oldest in Aizu, founded in the 4th year of Yōrō (720 AD).

However, the true story of Hōyō-ji lies in a place that cannot be imagined from this quiet present precinct. Once, this was the largest base for the faith of the sacred peak, Mount Iide, stretching south from Aizu.

The "Betto-ji" that oversaw Mount Iide

Mount Iide, standing at an elevation of 2,105 meters at the border of Fukushima, Niigata, and Yamagata, has long been regarded as "the mountain where souls return after death" and was one of the centers of mountain faith in Tohoku.

Hōyō-ji has lived through a long era as the "Betto-ji" that oversees this faith in Mount Iide—a temple that serves as the headquarters of faith.

At its peak, it is said that 33 monk lodges lined the precincts. Many ascetics and worshippers visited here, donned their ceremonial attire, offered prayers, and then headed to the mountain.

(The position of Betto later moved to Renge-ji in the 8th year of Tenbun (1539). However, even during its time as Betto, Hōyō-ji was the center of faith in this area for over 800 years.)

Boys at the age of 13 take on life-threatening challenges

There is another aspect of the ascetic practices on Mount Iide that must not be forgotten.

In the villages of Aizu, there has long been a rite of passage where boys who turn 13 are recognized as "full-fledged men" by climbing Mount Iide.

However, this is by no means a light "ritual." Children climb a mountain over 2,000 meters high with the equipment of that time. Many boys lost their lives.

Before the ascent, the boys underwent strict training for 3 to 7 days at the Kannon hall of Hōyō-ji.

  • Kessai (purification) — to cleanse oneself and abstain from meat and foul substances
  • Mizugori (water purification) — to bathe in cold water and dispel impurities
  • Inscription on the pillar - Leave your name and a prayer for a "safe return" on the pillar of the Kannon Hall.

Thus, the boys who had prepared their minds and bodies headed towards the mountains.

The determination of the boys remains on the pillar.

On the pillar of the Kannon Hall, there are still traces of inscriptions left by the boys before their ascent.

Names, ages, dates, and short words praying for safety. These are the handwritten notes of boys from over 100, 200 years ago.

"I will endure this training" "I will return safely"

In every character they wrote, the child's fears, determination, and thoughts for their family are evident. Perhaps there were boys who left only their inscriptions without returning from the mountains.

Walking after knowing, Hōyō-ji

Now, if you visit Hōyō-ji, it appears to be a tranquil temple set in a quiet rural area. The tourist guidebooks simply mention it as "one of the Five Cherry Blossoms of Aizu - Tora-no-O Sakura" and "Important Cultural Property of the Prefecture - Three-Story Pagoda."

When we guide visitors at Hōyō-ji, we ask them to approach the pillar of the Kannon Hall first and take a closer look. The moment they whisper, "Oh, I can see the characters", their expressions change. The experience of visiting the main hall from there becomes entirely different.

When you walk knowing that this was once a grand temple with 33 monk quarters and a place where 13-year-old boys underwent life-threatening training every summer, a completely different landscape emerges.

If you stop in front of the Kannon Hall, the image of boys bathing in cold water suddenly overlaps with the precincts. Looking up at the pillar, the faint traces of inscriptions seem to speak across time.

I think that's what travel is ultimately about. It's not about where you travel, but how much you know and walk.

If you are visiting Hōyō-ji

Hōyō-ji is located in Suzuribayashi, Aizumisato Town, Ōnuma District, Fukushima Prefecture. It is about a 30-minute drive from Aizuwakamatsu City. It is situated in the rural area heading south from Aizuwakamatsu and Tsuruga Castle.

Three-Story Pagoda and Tiger's Tail Cherry Blossom

The three-story pagoda in the precincts is designated as an important cultural property of Fukushima Prefecture (not nationally designated. The three-story pagoda in the snow country is rare and tells the story of the weight of this temple's history). In spring, one of the Aizu Five Cherry Blossoms, the "Tiger's Tail Cherry Blossom," blooms in the precincts, and the combination of cherry blossoms and the three-story pagoda creates one of the finest spring scenes in Aizu.

Kannon Hall and the Inscribed Pillars

The inscriptions left by boys on the pillars of Kannon Hall have faded over time to the point that they can easily be overlooked if you're not careful. When you visit, be sure to get close to the pillars and look for those traces.

Places to Visit Together
