Tsurugajo Castle: The Red-Tiled Fortress Behind Aizu's Unbreakable Samurai Spirit

# Tsurugajo Castle: The Red-Tiled Fortress Behind Aizu's Unbreakable Samurai Spirit

Most travelers rush through Aizu-Wakamatsu on a day trip from Tokyo, snap a castle photo, and leave thinking they've seen it. They haven't even scratched the surface. This small city in western Fukushima carries one of the most intense, heartbreaking, and fiercely preserved samurai legacies in all of Japan — and the castle at its center is not a relic. It's a statement.

## Why Aizu People Still Say 'Naranu Mono wa Naranu' — The Samurai Code That Never Died

Walk into any school in Aizu-Wakamatsu and you might hear a phrase that sounds like it belongs in a period drama: *"Naranu mono wa naranu mono desu"* — "What must not be done, must not be done." It's the final line of the *Jū no Okite*, the "Ten Rules" drilled into the children of Aizu samurai at the *Nisshinkan*, the domain's elite academy. These weren't abstract philosophies. They were daily behavioral codes: don't lie, don't bully, don't act in cowardice. And they're still taught — in modified form — in local elementary schools today.

This isn't nostalgia or cosplay. Aizu was on the losing side of the Boshin War in 1868, branded as traitors by the victorious Imperial forces. The punishment was savage: mass displacement, starvation, and decades of institutional discrimination. The people here didn't forget. Instead, they doubled down on their identity. The samurai code became an act of cultural survival.

You can visit the reconstructed Nisshinkan (admission ¥650) about 15 minutes by car northwest of the castle. It's a sprawling complex where kids once learned archery, astronomy, swimming, and Confucian ethics — all before the age of fifteen. The astronomy classroom alone, with its painted celestial globe, is worth the trip.

**Pro tip:** Most tour buses skip Nisshinkan entirely in favor of the castle. Go early in the morning and you'll likely have the place almost to yourself — particularly the archery range, which still has a visceral, austere beauty that no castle museum can match.

## The Red Tiles Most Visitors Photograph But Few Understand: What the 2011 Restoration Really Meant

Here's what most visitors don't know: that gorgeous red-tiled roof on Tsurugajo wasn't always red. For over four decades after the 1965 concrete reconstruction, the castle wore generic gray tiles, identical to dozens of other rebuilt castles across Japan. It looked fine. It just wasn't *right*.

The original Tsurugajo, as it stood during the brutal 1868 siege, had distinctive reddish-brown glazed tiles — *akagawara* — made from iron-rich local clay. These tiles weren't decorative. They were functional, designed to resist the harsh Aizu winters where freeze-thaw cycles shattered ordinary roof tiles. When Imperial forces bombarded the castle for a month straight, the walls crumbled but the roof held. That detail mattered enormously to locals.

In 2011 — the same year the Tohoku earthquake and Fukushima nuclear disaster devastated the region — Aizu-Wakamatsu completed a painstaking restoration of the roof to its original red tile. The timing was no coincidence. Fukushima was reeling from radiation fears, tourism had collapsed overnight, and the region was fighting an existential battle against stigma. Restoring Tsurugajo's true face was a deliberate act of defiance: *We are still here. We remember who we are.*

Today, Tsurugajo is the only major Japanese castle with red tiles, making it instantly recognizable. The castle interior (admission ¥520, or ¥830 combo with the Rinkaku tea house) houses a well-curated museum covering the Boshin War, but honestly, the top-floor observation deck and the exterior view from Tsurumi Park are where the emotional impact hits hardest — especially during cherry blossom season when over 1,000 *somei-yoshino* trees explode around the moat.

**Local secret:** Walk to the south side of the castle grounds to find the *Rinkaku* tea house, a Sen no Rikyu-lineage tea room where you can drink matcha (¥600 with a sweet) overlooking a pond that most tourists never reach because they exit from the main gate and head straight to the parking lot.

## Byakkotai Hill and the View That Ended Everything: Walking the Route the Teenage Samurai Took

Of all the stories embedded in Aizu-Wakamatsu, the *Byakkotai* — the White Tiger Corps — is the one that will stay with you longest, and the one that sits heaviest.

In the autumn of 1868, as Imperial forces closed in on the city, the Aizu domain mobilized everyone, including a reserve unit of boys aged fifteen to seventeen. Twenty members of the Byakkotai's *Shichu Nitai* squad retreated through enemy lines to Iimori Hill (*Iimoriyama*), east of the castle. Exhausted, wounded, and separated from their commanders, they looked down at the city and saw black smoke billowing over Tsurugajo. Believing the castle had fallen and their lord was dead, nineteen of them committed ritual suicide on the hillside. They were wrong. The castle was still fighting. The smoke came from burning buildings in the town below.

One boy, Iinuma Sadakichi, survived — his wound wasn't fatal — and lived until 1931, carrying the weight of that day for over sixty years.

You can walk the route today. From Iimoriyama's base, take the gentle slope path (skip the ¥250 escalator unless mobility is a concern; the walk is only 10 minutes). At the top, you'll find the nineteen graves lined up in a row, always with fresh incense burning. The view of Tsurugajo from this spot is clear on most days — and standing there, seeing how close and yet how impossibly far the castle must have felt to those boys, is genuinely devastating.

Nearby, you'll notice an unexpected monument: a Roman column gifted by Mussolini's Italy in 1928 and an iron eagle from Nazi Germany. These are uncomfortable artifacts of how the Byakkotai story was co-opted by foreign fascist movements romanticizing "beautiful death." The local museum (¥400) addresses this context honestly, which is worth respecting.

**Pro tip:** Visit the graves early morning before tour groups arrive (by 9:30 AM it gets crowded). The incense smoke drifting over the graves against a quiet sky is an image that needs no filter.

## Beyond the Castle Walls: Sake Cellars, Ouchi-juku, and the Living Samurai Culture Tourists Miss

Aizu-Wakamatsu has some of the best sake in Japan, and this isn't hype — it's geography. Cold, clean water flows from the surrounding mountains, and the region's rice and brewing traditions run centuries deep. The city has several active breweries you can visit, but start with **Suehiro Sake Brewery** (*Suehiro Shuzo*, free tours, tastings included), a ten-minute walk from the castle. Their *Kasen* label is a local staple, and their café inside a converted *kura* warehouse serves sake-infused desserts, including a sake kasu cheesecake that's dangerously good. **Miyaizumi Meijō** is another excellent stop with a small museum and tasting counter — try their *Sharaku* brand, which has become a darling among Tokyo sake bars.

For a half-day side trip, take the train to **Yunokami-Onsen Station** (about 40 minutes on the Aizu Railway, ¥1,190), then a bus (¥350) to **Ouchi-juku**, a preserved Edo-period post town that looks like it was yanked out of the 17th century. The thatched-roof houses are real — people still live and work in them. Try the signature dish, *negi soba* — buckwheat noodles you eat using a whole raw leek as your chopstick. It sounds absurd. It works. **Misawa-ya** near the center of the village does a reliable version for around ¥1,100.

Back in the city, don't overlook **Aizu Bukeyashiki** (¥850), a reconstructed samurai residence compound that's far more atmospheric than it sounds. The sprawling estate includes a rice-polishing mill, a tea ceremony room, and a section dedicated to the women of Aizu who fought — and died — during the siege.

**Local secret:** The Aizu Railway line to Ouchi-juku is scenic and mostly empty on weekday mornings. Sit on the left side heading south for river valley views that rival any tourist train — without the premium ticket price.

## Visiting Like a Local: Seasonal Timing, the Free Volunteer Guides, and Where Aizu Residents Actually Eat Nearby

Timing matters here more than most places. **Late April** is peak cherry blossom season at Tsurugajo, and the castle hosts evening illuminations that turn the moat into a mirror of pink and white — it's crowded, but worth it. **February** brings the *Aizu Candle Festival* (*Aizu Erosoku Matsuri*), when thousands of hand-made candles line the castle grounds and surrounding streets in the snow. It's magical, bitterly cold, and almost tourist-free. **Autumn foliage** peaks in early-to-mid November; Iimoriyama is spectacular then.

Aizu-Wakamatsu runs a **free volunteer guide program** through the tourist information center at JR Aizu-Wakamatsu Station. These are local residents — often retired — who guide in Japanese and sometimes English. Book at least a few days in advance through the Aizu-Wakamatsu Tourism Bureau website. They'll reshape your visit completely because they tell personal stories no signboard ever will.

For food, skip the tourist restaurants clustered near the castle parking area. Locals eat **sauce katsudon** (a pork cutlet over rice drenched in Worcestershire-style sauce, not egg) — it's the Aizu soul food. **Nakanoya** near Nanukamachi-dōri does an excellent version for around ¥900. For ramen, **Aizu Ramen** style features a flat, curly noodle in a rich soy-pork broth; try **Menpachi** near the station for a no-frills, deeply satisfying bowl (around ¥800). If you want traditional Aizu cuisine in a formal setting, **Takino** serves *kozuyu* — a delicate scallop-broth soup with taro, mushrooms, and wheat gluten that's been Aizu's ceremonial dish for generations.

**Pro tip:** Get a **Machiaruki Free Pass** (¥600/day) for unlimited rides on the Akabee and Haikarasan loop buses that connect the castle, Iimoriyama, Bukeyashiki, and the station. It pays for itself after two rides — and saves you from the surprisingly spread-out walking distances that catch many visitors off guard.
