堅破山（たつわれさん）は茨城県の多賀山地（阿武隈高地）にある標高658.3ｍの山である。角枯山、黒前山ともいう。
もとは角枯山（つのかれやま）と呼んだ。紀元前80年頃、蝦夷の征服に出征していた黒坂命（くろさかのみこと）がこの地で病気になって死んで以来、黒前山と呼ぶようになった（『常陸国風土記』、茨城郡の条）。江戸時代になって、八幡太郎源義家の故事にちなんだ岩に、西山公徳川光圀が「太刀割石（たちわれいし）」と名づけた。この名前からこの山を竪割山、竪破山と呼ぶようになった、とされている。
江戸期まで巨石・山岳信仰の山であった。山頂に黒坂命（くろさかのみこと）を祭神とする黒前（くろさき）神社がある。
1080年（寛治元年）、奥州遠征途上の八幡太郎源義家が黒前神社に戦勝祈願をした際、夢に現れた神に授けられた太刀を大岩に振り下ろすと、これが真っ二つに割れたという。
竪破山頂とその周囲には、この太刀割石（磐屋（いわくら））の他にも、不動石ほかの大きな奇石や滝があり、太刀割石、神楽石、甲石（堅破和光石）、舟石、胎内石、畳石（腰掛け畳石）、烏帽子石と、不動滝（奈々久良滝）、剣滝、龍馬滝をあわせて、七奇石三瀑と呼ぶ。
登山道沿いに見られる奇石のうち、不動石は土石流で運ばれてきた石、烏帽子石・手形石は崩落崖より転落・破砕した石、畳石は斜面がブロックで滑り落ちてきて・堆積した石。太刀割石、甲石、神楽石は小起伏面上にあり、花崗岩が風化され残った球状のコアストーンである。太刀割石はコアストーンがさらに木の根により節理面に沿って開口し、片方が転倒したもの。甲石は一部だけ破断しているもの･･･破断した断片が舟石。神楽石は5,6片の板状破片に開口しているもの。甲石→太刀割石→神楽石の順で開口の度が進んでいると見ることができる。 竪破山山頂には、黒前神社本殿の裏に大きな花崗岩塊（花崗岩の岩峰地形でトアとよばれる）が露出し、もともとの巨石信仰の岩座であったと思われる。胎内石は、竪破山の残丘北方稜線にある小岩峰（トア）の基部が南面の大崩壊の崩落崖にそって重力移動し、岩峰基部に歪みが集中して節理割れ目に沿って岩が抜け落ち浅い洞窟となったもの。

A reference article: Mt. Tatsuware - Wikipedia
tatuware mountain (I who stand) is a heap of 658.3m above sea level in Taga Mountains of Ibaraki (Abukuma Highlands). I say corner mountain with withered trees and plants, black Maeyama.
I called it a corner mountain with withered trees and plants (Mt. horn him) formerly. I came to call it with black Maeyama since Kurosaka life (kurosakano mikoto) that went to the front of conquest of the Ezo in about B.C. 80 got sick in this ground and died ("Hitachi country topographical record" the article of the Ibaraki county). It was the Edo era, and, to a rock in connection with a historical fact of Taro Yahata Yoshiie Minamotono, Prince Nishiyama Mitsukuni Tokugawa named "a sword broken stone" (he lets you stand and are broken and be). It is said that I came to call this mountain vertical Wariyama, Mt. Tatsuware from this name.
It was the climax of huge stone, mountain worship until Edo period. There is in front of black (kurosaki) Shinto shrine to assume Kurosaka life (kurosakanomikoto) an enshrined deity on the mountaintop.
It is said that this was broken right in the two when I swing down a sword granted to God who appeared in the dream in Oiwa when (the Kanji first year), Oshu expedition Taro Yahata Yoshiie Minamotono in the way prayed a Shinto shrine before black for the victory in 1080.
Sword broken stone (cave used as dwellings (reason and others)) these in the Mt. Tatsuware top and the people The の et al. have immovable stone other big curious stone and waterfalls and call sword broken stone, noh dance stone, former stone , Funaishi, interior of the womb stone, Tatamiishi (chair Tatamiishi), Eboshiishi and firmness waterfall (Nana Hisayoshi waterfall), sword waterfall, Taki Ryoma in total with Waterfall of three seven strange stones.
The stone which a slope slid down by a block as for the stone which had been carried by a mud flood, Eboshiishi, the bill stone as for the firmness stone among curious stones seen along the mountain trail in stone, Tatamiishi that a fall crushed than a collapse cliff and deposited. A sword broken stone, former stone, the noh dance stone are the spherical core stones which it is weathered, and granite was left on a small ups and downs side. A core stone opened the sword broken stone by the root of the tree more along a logic side, and one was inverted. Thing ... piece which broke that only part of former stone breaks is Funaishi. The noh dance stone opens on five or six slices of board-formed pieces. I can consider that an orificial degree advances in order of former stone → sword broken stone → noh dance stone. On the Mt. Tatsuware mountaintop, a big granite lump (called toa by the rock peak topography of the granite) is exposed to the back of the Shinto shrine main shrine before black, and it is thought that it was a rock seat of the huge stone faith of the cause cause. As for the interior of the womb stone, the base of the Koiwa peak (toa) in the monadnock north ridgeline of Mt. Tatsuware moved gravity along a collapse cliff of the great collapse of the southern aspect, and a distortion concentrated on a rock peak base, and a rock fell along a logic crack, and it was in a shallow cave.
