(Translated by Google) I will visit by car around the end of June 2024.
One of the 24 chashi ruins in the Nemuro Peninsula Chashi Ruins, which are registered as one of Japan's 100 Famous Castles, this is one of the chashi ruins built by the early modern Ainu people and maintained for tourists.
Chasi is translated as a fort, but it is also used for rituals, festivals, and negotiations, so if we were to compare it to modern times, it would be like a community center on a hill surrounded by a moat and a wall.
As you drive along Route 35, a sign for the Chashi ruins will appear on the north side, so it's easy to find as long as you don't drive too fast. If you deviate from the road and go down the slope, you will arrive at a free parking lot on open gravel with a frame line for four cars. There's plenty of space, so you can probably park two more cars.
If you walk for about 10 minutes up the narrow path in the field towards the top of the hill from the parking lot, you will see a staircase reinforced with metal. You can also reach the chashi ruins on the hill by climbing the gentle slope on the side without choosing the reinforced stairs.
In summer, the grass is so deep that it is difficult to find traces of moats or pit dwellings.
The Sea of Okhotsk seen from the top of the hill is spectacular, and if it was a clear day instead of cloudy, you could see the four northern islands and be deeply moved.
Japan's 100 Famous Castles stamps are available at the reception desk on the 1st floor of the Nemuro City Northern Territories Museum located at Cape Nosappu, 3 km to the east (6 minutes by car), and at the Nemuro City Tourist Information Center next to Nemuro Station, 21 km to the southwest (30 minutes by car). You can press it at two locations: at the desk in front of the reception desk on the 1st floor of the Information Center.
There are no public toilets, so let's do it around Cape Nosappu to the east.

2024年6月末頃に車で訪れる。
日本100名城に登録された24基ある「根室半島チャシ跡群」から観光客向けに整備された近世アイヌ人が築いたチャシ跡のひとつ。
チャシは砦と翻訳されてるが、儀式祭礼や談判も行われるので、現代に例えるなら濠と塀に囲まれた丘の上の公民館のイメージ。
道道35号線を走ると北側にチャシ跡の案内標識が現れるので、速度を出し過ぎない限り見つけ易い。道道から外れて坂道を降りると自動車4台分の枠線が記された露天砂利の無料駐車場に着く。余地が広いのであと2台分は駐められそう。
駐車場から丘の上を目指して原っぱの中の細道220mを10分ほど歩けば金属で補強した昇り階段が現れる。補強階段を選ばずに脇のなだらかな坂道を昇っても丘の上のチャシ跡にたどり着ける。
夏は草が深いので濠や竪穴式住居の痕跡を見つけにくい。
丘の上から眺めるオホーツク海は壮観で、曇天じゃなくて晴天なら北方四島が見えて感動が深かったろう。
日本100名城スタンプは、東へ3km(車で6分)先の納沙布岬にある根室市北方領土資料館1階受付、西南へ21km(車で30分)先の根室駅の隣にある根室市観光インフォメーションセンター1階受付前の机、の2箇所でで押せる。
公衆トイレは無いので、東の納沙布岬あたりで済ませよう。

(Translated by Google) 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 History and Nature Museum
・Nemuro City Tourist Information Center (in front of Nemuro Station)

根室には、たくさんのチャシ跡があるけど、「チャシ」とは?
調べたらアイヌ語で柵、砦という意味で、祭りの場や聖域として多目的に使用されていたらしい…
100名城のひとつ。
駐車場があるので、そこに停めて少し歩けばわかります。
今は何もない所ですが、貴重な場所ですね。
お城スタンプは、
・根室市歴史と自然の資料館
・根室市観光インフォメーションセンター(根室駅前)
で、押す事が出来ます。
(Translated by Google) (August 26, 2025) No. 1 of the Top 100 Castles, with seals located at various locations. I used the seal from the Tourism Association in front of the station, but it's in poor condition, with some lightly separated color patches. I couldn't find the seal composition on site, but after reading other people's experiences, it seems to be looking at the mound from the southeast.
It took a lot of effort, travel, and time to reach the castle ruins. Domestic flights, airport shuttles, two nights in Kushiro to accommodate travel time, trains, buses, and walking—and all I had to do was see this mound on the coast? For a moment, I was overwhelmed with emotions, stunned. But then I smiled and continued my journey. I understand the historical significance of this place, but it just doesn't justify the significant expense, so I can only give it one star. The castle ruins lasted a maximum of 15 minutes.
I arrived at the Cape Nosappu bus stop at 11:49 AM and took the 3:10 PM bus. This gave me plenty of time to walk back and forth from the stop, explore the Cape's sights, and find a place to rest and eat. The museum seems to offer electric bike rentals, but even if this shortens the walking time, the final itinerary will still be subject to the bus schedule, so using an electric bike is not very effective.
There are no supplies here, so it's recommended to prepare well beforehand. The overall plan for the siege must be carefully planned in advance, and no mistakes can be made. After all, a plan that spirals out of control is very unpleasant.

(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。
