What Travellers Say
Reviews Summary
Visitors find the Nemuro Peninsula Chashi Sites profoundly moving due to their historical significance and stunning, remote coastal scenery. While the lack of traditional castle structures and the challenging access are noted drawbacks, the unique Ainu heritage and the '100 Famous Castles' stamp make it a worthwhile pilgrimage for dedicated travelers.
"Number 1 on the list of Japan's 100 Famous Castles. This is also the most difficult to reach, so I've chosen it as the final stop on my "100 Famous Castles of Japan" journey.
Standing in the wind, gazing at the northern coastline, an indescribable feeling of emotion and loneliness welled up in my heart. There are no towering castle towers or magnificent stone walls here, only ruins scattered across the wilderness and the sound of the wind, quietly telling the history of this borderland. Imagine centuries ago, the Japanese and Ainu peoples clashed, interacted, and coexisted on this land. The weight of history and the silence of nature intertwine to create a unique atmosphere.
As I placed the final seal on the "100 Famous Castle Seals," it felt like I had completed a long pilgrimage. From south to north, from famous castles to ancient villages, each one records a different facet of Japanese history and reflects the perseverance and passion I've carried along the way. The wind in Nemuro was cold, but my heart was warm. In that moment, I deeply realized that travel is not just about the destination, but a dialogue with time, land, and memory. My journey to Japan's 100 Famous Castles has come to a close. The Nemuro Peninsula Castle Ruins, located at the easternmost tip of Hokkaido, are a significant historical site of Japan's exchanges with the north. Preserved here are numerous Japanese defensive structures dating from the 16th to 18th centuries, bearing witness to encounters and conflicts with the Ainu people. Now listed as one of Japan's 100 Great Castles, it is renowned for its unique frontier history and vast natural landscapes."

"(2025.8.26) 百大名城No.1,印章設於多點。我是使用設於車站前観光協会的印章,不過該印章的狀況不大好,有淺層的分離色塊。印章構圖我現場沒找到,回來看其他人心得分享,似乎是從東南方望向此土丘。
花了好大的工夫及非常大的移動及時間成本,才抵達的城跡。國內線+機場巴士+配合交通時間釧路待兩晚+電車+公車+走路,結果攻過來,就為了要我看這一個在海岸邊的土丘?一瞬間是有點百感交集,傻眼。但也是笑一笑,繼續我的攻城之旅。我明白這個地點有其歷史意義,但實在是平衡不了我付出大量成本的感受,所以我也只能給一星了。城跡滯留時間,至多15分鐘。
我是11:49抵達納沙布岬公車站牌,搭下午3:10的公車離開。這樣的時間區間,足夠讓我從站牌來回步行攻城,然後納沙布岬一帶景點都有踩到,也有找個地方坐下來休息用餐。資料館似乎可租用電動腳踏車,但就算縮短了步行時間,最終行程也還是會受制於巴士時刻表,所以使用電動腳踏車的意義就不大了。
這邊是完全沒得物資補給,建議備好物資再前來攻城。攻城的整體計畫,事前務必縝密規劃,然後不能有閃失,畢竟這邊行程滾雪球可是非常不好玩的。"

"There are many remains of chashi in Nemuro, but what does "chashi" mean?
I looked it up and found out that it means fence or fortress in Ainu language, and was used for various purposes such as a festival site and sacred area...
It is one of the 100 famous castles.
There is a parking lot, so park there and walk a little to find it.
There is nothing there now, but it is a precious place.
You can get the castle stamp at

・Nemuro City Tourist Information Center (in front of Nemuro Station)"

Frequently Asked Questions
🚇 🗺️ Getting There
The Nemuro Peninsula Chashi Sites are quite remote. The most common approach is to fly into Memanbetsu Airport (MMB) or Kushiro Airport (KUH), then take a train or bus to Nemuro City. From Nemuro City, renting a car is highly recommended for exploring the various chashi sites scattered across the peninsula, as public transport is limited. Alternatively, local buses operate, but schedules are infrequent and require careful planning.
Access can be challenging due to the remote location and the dispersed nature of the sites. While some sites have parking lots, reaching them may involve short walks on uneven terrain. It's crucial to research the specific accessibility of each chashi you plan to visit.
For maximum flexibility and to visit multiple chashi sites efficiently, renting a car in Nemuro City is the best option. This allows you to set your own pace and easily navigate between locations.
Getting to Nemuro from Tokyo typically involves a flight to Hokkaido (e.g., Sapporo, Memanbetsu, or Kushiro) followed by a train or bus journey, which can take several hours. Factor in travel time to the airports as well.
While not as common as tours for more mainstream attractions, some local tour operators in Nemuro might offer specialized historical or nature tours that include the chashi sites. It's advisable to inquire with the Nemuro City Tourist Information Center for current options.
🎫 🎫 Tickets & Entry
No, the chashi sites themselves are historical ruins and are generally open to the public without an entrance fee. The primary cost will be transportation to and within the Nemuro Peninsula.

🎫 🧭 Onsite Experience
You'll find remnants of Ainu defensive structures and meeting places, often appearing as earthworks or mounds on the landscape. The experience is more about historical contemplation and enjoying the vast, windswept coastal scenery than seeing grand architecture.
Generally, there are very few amenities directly at the chashi sites. Some may have basic parking areas. It's essential to bring your own water, snacks, and any other necessities.
Chashi were defensive structures and ceremonial sites used by the Ainu people. The Nemuro Peninsula sites are particularly important as they represent the historical interactions and sometimes conflicts between the Ainu and Japanese settlers in this frontier region.
Absolutely! The dramatic northern coastline, the open landscapes, and the historical context make it a unique and photogenic location, especially during sunrise and sunset.
Visiting a single chashi site might take 15-30 minutes. However, to explore multiple sites and account for travel time between them, it's best to dedicate at least half a day, or even a full day if you're interested in the broader Nemuro area.
🍽️ 🍽️ Food & Dining
Nemuro City is known for its fresh seafood, especially crab and sea urchin. You can find restaurants and local eateries in Nemuro City. Daihachi-shokudo is a popular spot for crab dishes.
Dining options are very scarce on the peninsula itself. It's advisable to eat in Nemuro City before heading out to explore the chashi sites or pack your own food and drinks.
Nemuro is famous for its king crab (tarabagani), hairy crab (kegani), and sea urchin (uni). Trying crab ramen or crab fried rice is a popular choice.
Vegetarian and vegan options might be limited, especially in smaller establishments. Seafood is the dominant cuisine. It's best to inquire directly at restaurants about available options.
Yes, bringing your own food and drinks is highly recommended, especially if you plan to spend a significant amount of time exploring the peninsula. This ensures you have sustenance without relying on scarce local options.
📸 📸 Photography
Golden hours, shortly after sunrise and before sunset, offer the most dramatic lighting for capturing the landscapes and the subtle earthworks of the chashi. Midday can be harsh, but still offers clear views.
A wide-angle lens is great for capturing the expansive coastal scenery. A telephoto lens can be useful for distant shots of the sea or wildlife. Don't forget a sturdy tripod for low-light conditions or long exposures.
Anywhere along the coastline offers stunning views. Look for elevated points near the chashi sites that provide panoramic vistas of the sea and the rugged terrain. The approach to Cape Nosappu also offers great photo opportunities.
Be mindful of the weather, which can change rapidly. Strong winds are common. Also, respect the historical nature of the sites and avoid disturbing any remnants.
Drone usage regulations can vary. It's advisable to check local ordinances and obtain any necessary permissions before flying a drone over historical sites or protected natural areas.

The Historical Significance of Chashi
These chashi represent a crucial part of Japan's frontier history, particularly concerning the interactions and sometimes conflicts between the Ainu and Japanese settlers from the 16th to 18th centuries. The Nemuro Peninsula, being at the easternmost tip of Hokkaido and close to the Northern Territories, has a unique geopolitical and historical context. Visiting these sites provides a profound understanding of this complex past, far removed from the more commonly known samurai-era castles.
While the physical remains might be subtle – often earthworks, mounds, or stone foundations – their historical weight is immense. They are a testament to the resilience and cultural richness of the Ainu people and the historical significance of this borderland. The experience of standing on these ancient grounds, gazing at the northern coastline, evokes a unique sense of history and place.
Navigating the Remote Nemuro Peninsula
Public transportation on the peninsula is limited, with infrequent bus services that require meticulous schedule checking. For those relying on buses, it's essential to group nearby sites together and be prepared for significant waiting times. The roads leading to some chashi sites are well-maintained, but others might be unpaved or require careful driving. Always check local road conditions, especially during adverse weather.
When planning your visit, remember that amenities on the peninsula are scarce. It's highly recommended to pack essentials like water, snacks, and appropriate clothing, as there are few shops or restaurants once you leave Nemuro City. The experience is about immersing yourself in the natural beauty and historical solitude, so preparation is key to a rewarding trip.
The '100 Famous Castles' Stamp Quest
The stamp itself can be acquired at the Nemuro City Tourist Information Center, conveniently located in front of Nemuro Station. This makes it a relatively accessible goal even for those who might not have extensive time to explore every single chashi site on the peninsula. The stamp serves as a tangible memento of your journey to this remote and historically rich location.
While the physical sites may be ruins, the act of collecting the stamp connects you to a broader tradition of Japanese castle tourism and appreciation. It's a small but meaningful part of the overall experience, adding another layer to the journey of discovering Japan's diverse historical landscapes.
