Shiga Castles: Hikone Castle, Azuchi Ruins & Japan's Samurai Heritage by Lake Biwa
Why Shiga for Castles
Most travelers heading to Kansai visit Osaka Castle or Himeji Castle — both impressive, both famous, and both crowded. What many do not realize is that Shiga Prefecture, just east of Kyoto along the shores of Lake Biwa, holds two castle experiences that rival anything in the region: one intact, one destroyed, and both historically significant in ways that the more popular sites are not.
Hikone Castle (彦根城) is one of only 12 castles in Japan with an original surviving wooden keep. It has been standing since 1622 and is designated a National Treasure (国宝) — the highest cultural property classification in the country. According to the Hikone Castle official site, only five castle keeps in Japan hold this designation.
Azuchi Castle (安土城) no longer exists. Built by Oda Nobunaga in the 1570s, it was the first Japanese castle with a grand multi-story keep — the prototype for every castle tower that came after. It burned just three years after completion, following Nobunaga's assassination in the Honno-ji Incident (本能寺の変) of 1582. What remains are stone walls, foundations, and a steep hilltop that tells the story of Japan's most pivotal castle.
Together, they offer something no other prefecture can: a National Treasure castle you can walk through, and the ruins of the castle that changed Japanese architecture forever.
Hikone vs Azuchi at a Glance
| Hikone Castle | Azuchi Castle Ruins | |
|---|---|---|
| Status | Intact — original 1622 keep | Ruins — stone walls and foundations only |
| Designation | National Treasure | National Special Historic Site |
| Best for | Architecture, museum, mascot, gardens | History, hiking, imagination |
| Admission | ~¥1,000 adults (castle + garden) | ~¥700 adults |
| Time needed | 2-3 hours | 1.5-2 hours |
| Physical demand | Moderate (steep stairs inside keep) | Strenuous (500+ stone steps, 30-45 min climb) |
| From Kyoto | ~30 min by JR rapid | ~40 min by JR |
| Station | JR Hikone Station | JR Azuchi Station |
If your time is limited, Hikone is the higher-priority visit — you can touch, climb, and walk through original Edo-period architecture. If you are a history enthusiast or want to understand how Japanese castles evolved, Azuchi adds a dimension that no intact castle can provide.
Hikone Castle: Japan's National Treasure by Lake Biwa
What Makes Hikone Special Among Japan's Castles
Hikone Castle was built between 1603 and 1622 by the Ii clan (井伊氏), one of the most powerful feudal families under the Tokugawa shogunate. According to the Hikone Castle official site, the Ii family ruled from Hikone for approximately 250 years.
The keep is compact — three stories, smaller than Himeji — but what makes it remarkable is authenticity. Every wooden beam, every steep staircase, every defensive window is original. The architecture combines three distinct gable styles in a single structure, which is unusual among Japanese castles. The black-lacquered kato-mado windows are both decorative and functional.
Beyond the keep, the castle grounds include Genkyuen Garden (玄宮園), a 1677 landscape garden with pond views framing the castle tower, and the Hikone Castle Museum housing over 45,000 artifacts of the Ii clan. The combined ticket (castle, garden, and museum) costs approximately ¥1,500 (~$10) for adults.
For complete visitor details including hours, tickets, and Hikonyan schedule, see our Hikone Castle visitor guide.
Hikonyan and the Castle Town
Hikonyan (ひこにゃん) is Hikone's beloved mascot — a white cat dressed in the red samurai armor of Ii Naomasa. Created for the castle's 400th anniversary in 2007, Hikonyan performs daily at the castle grounds and draws significant crowds, especially on weekends. Check the official site for current performance times.
The walk from Hikone Station to the castle (about 15 minutes) passes through the old castle town, where you can find local shops and restaurants along the Iroha-matsu pine-lined approach road.
Azuchi Castle Ruins: Nobunaga's Lost Masterpiece
The Castle That Changed Everything
According to the Shiga Prefecture tourism site, Oda Nobunaga began construction of Azuchi Castle in 1576. Completed in 1579, it was revolutionary: the first Japanese castle with a lavishly decorated multi-story keep, featuring gold-leaf interiors, painted screens, and a design that elevated the castle from military fortification to symbol of political power.
Every major castle built after Azuchi — including Osaka, Himeji, and Hikone — drew on innovations that Nobunaga introduced here. Azuchi Castle was, in architectural terms, the beginning of what we now recognize as the classic Japanese castle.
But Azuchi lasted only three years. In 1582, Nobunaga was betrayed and killed at Honno-ji temple in Kyoto. Shortly after, Azuchi Castle burned — whether by enemy action or accident remains debated by historians. What survives are massive stone walls, foundation stones that mark where the keep once stood, and a steep mountain path lined with the ruins of samurai residences.
What Remains and the Climb
Visiting Azuchi Castle ruins is a hike, not a stroll. From the base of the mountain, approximately 500 stone steps lead up to the keep foundations at the summit. The climb takes 30-45 minutes and is steep and uneven in places — good footwear is essential. Walking sticks are available at the entrance. Many visitors on Reddit and TripAdvisor note that the climb is rewarding but demanding, especially in summer heat.
At the top, the stone foundations mark the exact footprint of Nobunaga's keep. The views across Lake Biwa and the surrounding plains help you understand why Nobunaga chose this spot — it commanded the main routes between Kyoto and eastern Japan.

Visiting Both: A Shiga Castle Day Trip from Kyoto
Both castles are accessible by JR train from Kyoto Station along the Biwako Line:
| Route | Duration | Cost | Notes |
|---|---|---|---|
| Kyoto → Hikone (JR Biwako Line rapid) | ~30 min | ~¥580 | Direct |
| Hikone → Azuchi (JR Biwako Line) | ~30 min | ~¥500 | Requires backtracking west |
| Kyoto → Azuchi (JR Biwako Line) | ~40 min | ~¥680 | Direct |
A suggested itinerary for visiting both in one day:
- Morning: Depart Kyoto early. Arrive Hikone by 9:00. Visit the castle, garden, and museum (2-2.5 hours).
- Midday: Train from Hikone to Azuchi (~30 min). Lunch near Azuchi Station.
- Afternoon: Climb the Azuchi Castle ruins (1.5-2 hours including the hike).
- Return: Train back to Kyoto from Azuchi (~40 min).
This itinerary works but is a full day. If you prefer a more relaxed pace, split the visits across two days — spend an afternoon at Hikone combined with Lake Biwa sightseeing, and dedicate a separate morning to Azuchi.
Prices shown are approximate based on 2025 data. Check the official sites for current admission fees.
Practical Tips for Shiga Castle Visits
- Start with Hikone if short on time: It is the more complete experience — original keep, garden, museum, and mascot in one site.
- Wear hiking shoes for Azuchi: The 500 stone steps are steep and can be slippery. Sandals and dress shoes are not appropriate.
- Check Hikonyan's schedule: The mascot performs at set times daily. Check the Hikone Castle official site before your visit.
- Bring water for Azuchi: There are limited facilities on the mountain. Summer visits are hot and the climb is strenuous.
- Autumn and spring are best: Cherry blossoms at Hikone and autumn foliage at both sites are the peak viewing seasons.
- Combine with Lake Biwa: Shiga's castles sit along Japan's largest lake. The eastern shore offers cycling, boat tours, and onsen towns that complement a castle day trip.
