English: As the names that are similar to '及川 and 笈川' (OHIKAWA), there are 追川氏 and 生川氏, but it is not well known whether they are just phonetic equivalents, related or totally different names.
Japanese: 「及川・笈川」（おひかは）に似た姓としては、追川氏・生川氏があり、これらは当て字の違いにすぎず同系なのか、あるいはまったく別の姓なのか詳細不明である。
English: There also exist 老川氏, 翁川氏 (OIKAWA, おいかは) and 小井川氏 (OIKAWA, をゐかは), but they seem to be different names.
Japanese: また老川氏・翁川氏（おいかは）、小井川氏（をゐかは）等の苗字も存在するがこれらは別の姓であろう。
English: MINAMOTO no Yorimasa (Yorimasa BABA) was a famous samurai warrior and poet who appears in "Heike Monogatari" (The Tale of the Heike) and is renowned for getting rid of the nue (a creature of Japanese legend).
Japanese: 源頼政（馬場頼政）は『平家物語』の登場する有名な武将で歌人、鵺退治の伝説でも名高い。
English: There is the bloodline from his son, MINAMOTO no Nakatsuna, as well as one from Nakatsuna's younger paternal half-brother, Masatsugu OIKAWA.
Japanese: その子・源仲綱から出た系統と、仲綱の異母弟・及川政嗣から出た系統とがある。
English: Later, Nakatsuna's son MINAMOTO no Naritsuna governed OIKAWA manor in Tajima Province, Kinosaki County (near what is now Toyooka City) and identified himself as MINAMOTO no Naritsuna.
Japanese: 仲綱の子・源成綱はのちに但馬国城崎郡（今の豊岡市近辺）の及川荘を領し、源成綱と称した。
English: Naritsuna (Moritsuna)'s uncle, Masatsugu, identified himself as OIKAWA, whereupon Naritsuna and the Masatsugu bloodline flourished in Oshu, but later it went to ruin and consequently the Naritsuna bloodline flourished instead of this.
Japanese: 成綱（＝盛綱）の叔父・政嗣も成綱に従って及川を称し、この政嗣の系統が先に奥州において栄えたがのちに滅亡し、以後は成綱の系統がこれに代わって栄えた。
English: Masatsugu was a descendant whom his father Yorimasa left when he went to Oshu, leaving the capital, and among the families he became a pioneer of localization in Oshu.
Japanese: 政嗣は、父・頼政が奥州に下向した時に残した胤で、一族中では奥州土着の先駆けとなった。
English: Masatsugu was probably more than 40 years younger than his older paternal half-brother Nakatsuna and was probably younger than his cousin Naritsuna.
Japanese: 政嗣は異母兄・仲綱より40歳以上も若く、おそらく甥の成綱よりも歳下であった。
English: Apparently, Naritsuna also followed the Kamakura bakufu (Japanese feudal government headed by a shogun) because Naritsuna's elder brother, MINAMOTO no Aritsuna, joined MINAMOTO no Yoritomo when Yoritomo rose up in arms (the place name 'OIGAWA village' in Atsugi City, Kanagawa Prefecture, seems to have had a relationship with Naritsuna or Naritsuna's son Mitsutsuna OIKAWA, but formerly it was also written as '及河' and was properly read as 'OIGAWA' in a dull sound.
Japanese: 成綱の兄・源有綱は源頼朝の挙兵の際に参陣していることから、成綱もまた鎌倉幕府に従ったと思われる（神奈川県厚木市の「及川村」という地名は成綱または成綱の子・及川光綱の縁かとも思われるが、古くは「及河」とも書き「おいがわ」と濁って読むのが正しい。
English: Mitsutsuna's offspring Mitsushige OIKAWA became a retainer of the Yuki clan in Shimousa Province and was localized in Shimousa, and Mitsushige's offspring Mitsufusa OIKAWA became a retainer of the Shirakawa Yuki clan and obtained territory in Oshu (Fukushima Prefecture) (there is the place name 'Oikawa village' in Kitakata City, which may suggest that there was a relationship with the Oikawa clan in those days, but the birth of the place name was after the Shoo era and previously it was called Nikkuni).
Japanese: 光綱の子孫・及川光重は、下総国の結城氏の家臣となって下総に土着、その子孫・及川光房は白河結城氏の家臣となり奥州（福島県）にも所領を得た（喜多方市に「笈川村」という地名あり、あるいはこの頃の及川氏に関係あるやにも思われるが、この地名ができたのは承応年間以後のことでそれ以前は新国（にっくに）といった）。
English: The OIKAWA clan became a retainer of the KASAI clan, which had influence from the southern part of Iwate Prefecture to the north part of Miyagi Prefecture but, due to the consequent development, was divided into three family lines.
Japanese: 及川氏は岩手県南部から宮城県北部にかけて勢力を有した葛西氏の家臣となったが、その経緯から三つの家系に分かれている。
English: Initially, Masatsugu's grandson Sadatsugu OIKAWA became a retainer of the KASAI clan in the earliest time, but he was exterminated due to the reasons described below.
Japanese: まず政嗣の孫・及川定嗣がもっとも早期に葛西氏の家臣となっているが下に述べるようにのちに滅ぼされた。
English: Next, there was Yoritada OIKAWA, who became a retainer of the KASAI and moved to Oshu as one of Mitsutsuna's offspring.
Japanese: 次いで、光綱の子孫にも、葛西家臣となり奥州に移住した者として及川頼只がいた。
English: Mitsufusa OIKAWA's great-grandson Mitsumura OIKAWA was killed in the Yuki War, so that the line temporarily went to ruin; Mitsumasa's son Mitsumura OIKAWA lost his territories, ran away and sought refuge in the KASAI clan.
Japanese: 及川光房の曾孫・及川光政は結城合戦で討死、結城氏は一時滅亡となり、光政の子・及川光村はすべての所領を失い、逃げて葛西氏を頼った。
English: Mochinobu KASAI gave territories to Mitsumura and made him his retainer (at that time, many families seemed to remain in Shimousa; the OIKAWA clan concentrates in the northern part of Chiba Prefecture, and currently six percent of all OIKAWA clan are residents of Chiba Prefecture).
Japanese: 葛西持信は光村に領地を与えて家臣とした（この時、下総に残った一族もかなりいたらしく、千葉県北部に及川氏が集中しており、現在の全及川氏の6％が千葉県人）。
English: In the mid-fifteenth century (the Muromachi period), the offspring of Sadatsugu OIKAWA raised a rebellion against the KASAI clan, but Mitsumura suppressed it.
Japanese: 十五世紀中頃（室町時代）、及川定嗣の子孫は葛西家に対して謀叛を起こしたが、光村がこれを鎮圧。
English: Thus the Sadatsugu family line was destroyed, whereupon the Mitsumura family line took over; the OIKAWA clan gave rise to many branches, spread and increased throughout Oshu.
Japanese: それで定嗣の系統は滅亡し、光村の家系が取って代わり、及川氏は多くの分流を派生しつつ、奥州に増え広がった。
English: Currently, the OIKAWA family name centers on the middle and southern parts of Iwate Prefecture and the northern part of Miyagi Prefecture (53％ of all OIKAWA clan live in both prefectures), but was scattered around the prefectures of the Tohoku region such as Aomori, Akita, Yamagata and Fukushima.
Japanese: 現在、及川という苗字は岩手県の中部南部と宮城県の北部を中心としつつも（両県合わせて全及川氏の53％）、青森・秋田・山形・福島の東北地方各県に散在している。
English: During the early sixteenth century (the mid-Sengoku (Warring States) period), Mitsumura's grandson Shigetane OIKAWA fought with the Esashi clan but was defeated, and consequently the Mitsumura family line went to ruin.
Japanese: 十六世紀初頭（戦国時代中頃）、光村の孫・及川重胤は江刺氏と戦って敗れ、光村の家系は衰退した。
English: During the mid-sixteenth century (the late Sengoku period), in the time of Yoriie OIKAWA, a grandson of Yoritaka, they were deprived of the territory by his master, the KASAI clan; subsequently, the family line went to ruin and took up farming again.
Japanese: 十六世紀中頃（戦国時代末期）、頼高の孫・及川頼家の時、同族間の内紛により主君葛西氏に領地を召し上げられてこの家系も没落し多くは帰農した。
English: Shigeuji OIKAWA survived as a retainer of the KASAI clan although the Shigetane family line declined, but later, during the time of Hideyoshi TOYOTOMI, the KASAI clan was destroyed by Hideyoshi; all the family became ronins (masterless samurai), and some of them joined Kasai-Osaki-ikki (the revolt of the former retainers of the Kasai and Osaki clans).
Japanese: また重胤の家系は衰えながらも及川重氏が葛西家臣として生き残っていたが、のちに豊臣秀吉の時代になり、葛西氏が秀吉に滅ぼされると一族はみな浪人となって、葛西・大崎一揆に加わる者もいた。
English: Eventually, some of them became retainers of the DATE and NANBU clans, like Shigehide OIKAWA (an offspring of Mitsumura) or Nobutsugu OIKAWA (a son of Yoriie).
Japanese: 最後には及川重秀（光村の子孫）や及川信次（頼家の子）のように、伊達氏や南部氏の家臣となるものも出た。
English: (Today, as for the OIKAWA family name, thirteen percent of it is in Hokkaido, seven percent in Tokyo and some of it is in the prefectures of Ibaragi, Saitama and Shizuoka).
Japanese: （現在、及川という苗字は北海道に13％、東京都に7％が住む他、茨城・埼玉・静岡の各県にもいる）。
English: In medieval times they were localized in Oshu as retainers of the KASAI clan; the three family lines rose and fell alternately, had conflicts with neighboring forces and spawned many branch families.
Japanese: 中世には葛西氏の家臣となって奥州に土着し、三つの家系が交互に興亡して近隣の諸勢力と抗争しつつ、多くの分家庶流を生んで繁茂した。
English: Sadatsugu OIKAWA, Shigeuji OIKAWA, Shigetane OIKAWA, Tsunashige OIKAWA, Mitsumura OIKAWA, Yorio OIKAWA, Yorikane OIKAWA, Yoritaka OIKAWA, Yoritada OIKAWA
Japanese: 及川定嗣・及川重氏・及川重胤・及川綱重・及川光村・及川頼雄・及川頼兼・及川頼高・及川頼只
English: Various crests were used depending on the family, but ultimately there were many Katabami (cuckooflower) crests.
Japanese: 家により多様な家紋が使われているが、しいていえば片喰（かたばみ）紋系が多い。
English: Katabami' crest/'Maruni Katabami' crest/'Ishimochi Jinuki Katabami' crest/'Maru ni Chukage Ken Katabami' crest (examples of Iwate Prefecture)

English: There are branch families from OIKAWA clan such as 'OTOKOZAWA clan,' 'MASUBUCHI clan,' 'SHISHIORI clan,' 'ONODERA clan' (ONODERA of the MINAMOTO family) and so on.
Japanese: 及川氏から分派した家には「男沢氏」「鱒淵氏」「鹿折氏」「小野寺氏（源姓小野寺）」等がある。
English: During the Battle of Jugorigahara, which was fought in September and October 1588, the allied troops of Kagekatsu UESUGI and Yoshikatsu DAIHOJI, led by Shigenaga HONJO, fought against Yoshiaki MOGAMI's troops, which were led by the brothers Yoshinaga and Katsumasa TOZENJI.
Japanese: 十五里ヶ原の戦い（じゅうごりがはらのたたかい）は天正16年（1588年）8月、本庄繁長率いる上杉景勝・大宝寺義勝連合軍と東禅寺義長・東禅寺勝正兄弟率いる最上義光軍との戦である。
English: The Shonai district received high economic benefits based on its inclusion of the Shonai plains and Sakata Minato port, so various clans including Uesugi, Mogami and Onodera watched for an opportunity to plunder this area.
Japanese: またこの地域は庄内平野や酒田市湊を抱えており経済的価値が高く、周囲の上杉氏や最上氏、小野寺氏などが獲得を狙っていた。
English: During the 1580s, when the lord of Yamagatajo Castle, Yoshiaki MOGAMI, who was rapidly expanding his territory, launched an attack on the Shonai district, the lord of Ourajo Castle, Yoshiuji DAIHOJI, confronted Mogami's troops with the help of Shigenaga HONJO, who had been an alliance from the days of his father Yoshimasu DAIHOJI.
Japanese: 1580年代、急速に領土を拡大していた山形城主最上義光の攻勢がついに庄内にも及ぶようになると、尾浦城主大宝寺義氏は父・大宝寺義増の代からの盟友本庄繁長の支援を受けてこれに対抗した。
English: In 1583, using Yoshinaga TOZENJI, a senior vassal of the Muto clan and the lord of Tozen-ji Castle, Yoshiaki assassinated Yoshiuji.
Japanese: 天正11年（1583年）、義光は武藤氏重臣・東禅寺城主東禅寺義長を利用して義氏を暗殺。
English: Yoshiaki, while continuing his attack, killed Yoshiuji's younger brother and successor as the head of the family, Yoshioki DAIHOJI, during November and December 1587.
Japanese: 天正15年（1587年）11月には家督を継いだ弟の大宝寺義興をも攻め殺した。
English: Subsequently, Shigenaga HONJO's son Yoshikatsu DAIHOJI, who had been adopted by Yoshioki DAIJOJI, was determined to resume his power while taking refuge with his biological father.
Japanese: この時、義興の養子となっていた本庄繁長の子・大宝寺義勝は実父の下に逃れて捲土重来を誓った。
English: When Masamune DATE intervened in an internal disturbance of the Osaki clan by using force, which is called the Battle of Osaki in January and February 1588, since the Osaki family was the head house of the Mogami family as well as the family home of Yoshiaki's lawful wife, Yoshiaki sent reinforcements to Osaki's territory.
Japanese: 翌天正16年（1588年）1月、最上家の本家にあたり正室の実家でもある大崎氏の内紛に伊達政宗が武力介入すると（大崎合戦）、義光は政宗を討つべく大崎領に援軍を派遣した。
English: Kagekatsu UESUGI sent troops to conquer the Shonai district, by taking advantage of the situation in which Yoshiaki was busily occupied with the battle against Masamune.
Japanese: 義光が政宗との戦に忙殺されているのを好機と見た上杉景勝は、庄内占領のため兵を動かした。
English: Although the battle was initially a pitched battle, the Uesugi's allied troops, who outnumbered those of Mogami, gradually drove their opponent into a corner.
Japanese: 合戦開始当初は両軍互角の状況だったが、次第に数で劣る最上軍が追いつめられていった。
English: When Katsumasa was informed of his brother's death, he also charged the opponent's headquarters alone and made a surprise attack on Shigenaga HONJO with his sword; but he was killed by Shigenaga and his close retainers.
Japanese: 兄戦死の報を受けた勝正もまた単身本陣へ突入し、不意をついて本庄繁長に斬りかかったが逆に繁長と側近達に討ち取られた。
English: The sword Katsumasa used at this time was the noted Masamune sword, which was later passed into the hands of Shigenaga HONJO to be renamed Honjo Masamune (the noted sword "Masamune" once owned by Shigenaga HONJO).
Japanese: この時勝正が手にしていたのが名刀正宗で、本庄繁長の手に渡り本荘正宗と言われるようになったという。
English: The Mogami's troops were defeated despite their continual resistance at places including Asahiyama-jo Castle; consequently, the Shonai district was incorporated into the territory of Kagekatsu UESUGI.
Japanese: この後、最上軍は朝日山城などで抵抗を続けたが敗れ、庄内地方は上杉景勝の版図となる。
English: Shigenaga advanced his troops further as he was spurred by his side's victory, but he was obliged to withdraw due to a fierce counter-offensive by the Mogami troops at Higashine.
Japanese: 繁長は余勢を駆ってさらに兵を進めたが、東根で最上勢の猛反撃に遭い撤退した。
English: The battle broke out after the proclamation of a cease-fire edict for the Ou region issued by Hideyoshi TOYOTOMI in December 1587 and January 1588; which means that the allied dispatch of the troops by Uesugi should have been unlawful.
Japanese: この戦が起きたのは、天正15年（1587年）12月の豊臣秀吉による奥羽惣無事令の発令後であり、本来この出兵は認められないはずであった。
English: When Yoshikatsu was punished by being deprived of his fief the Shonai district in 1591, the district was given to Kagekatsu UESUGI.
Japanese: さらに、天正19年（1591年）に義勝が改易された後、庄内を与えられたのは上杉景勝であった。
English: Yoshiaki MOGAMI had a deep hatred for Hideyoshi and the Uesugi clan, becauase he was infuriated by the decisions made by Hideyoshi and because he was grievously shocked by the death of his daughter Komahime, who was a concubine of Hidetsugu TOYOTOMI and, as instructed by Hideyoshi, executed in the Hidetsugu Incident.
Japanese: この裁定と秀次事件における駒姫の死とが重なって、最上義光は秀吉や上杉氏に対して深い憎悪の念を抱いた。
English: Yoshiaki MOGAMI won back the Shonai district from Uesugi in May and June 1601.
Japanese: 最上義光が上杉から庄内を奪還するのは、慶長6年（1601年）4月のことであった。
English: This was one of the two factions in the Toyotomi government with Kiyomasa KATO and Masanori FUKUSHIMA, etc. taking a leading part, and it is often mentioned in contrast with the Bunchi-ha (also called the Bunri-ha) which was led by Mitsunari ISHIDA, Yukinaga KONISHI and others.
Japanese: 加藤清正・福島正則などを中心とした豊臣政権内部の2つの派閥の一つで、石田三成・小西行長などの「文治派（文吏派とも）」と対比して呼ばれる。
English: Following the death of Hideyoshi TOYOTOMI, a bitter rivalry between the two factions developed and Ieyasu TOKUGAWA who was one of the Gotairo (Council of Five Elders) and received the support from the Budan ha interfered in this conflict.
Japanese: 豊臣秀吉死後激化したこの二派の対立に五大老の一人である徳川家康が介入（武断派に支持された）。
English: As one of the prominent figures in the administration, Toshiie MAEDA who was also one of the Gotairo died around this time, and there was no one left to stop the contention, which led to the Battle of Sekigahara.
Japanese: さらに同じく五大老の一人で家康と並ぶ政権の重鎮であった前田利家の死により対立を止める者が居なくなり、関ヶ原の戦いの要因の一つとなった。
English: Although most military commanders of the Budan-ha were the ones who rendered distinguished services in a number of battle fields (especially in the Bunroku-Keicho War) (their name "Budan" meaning resorting to military means came from this fact), they could not be said to have had high positions in the center of the administration.
Japanese: 武断派の武将たちは、今まで数々の戦場（特に文禄・慶長の役）で、大きな戦功を立てたたものが多かった（これが武断派の名称の由来となった）が、その功績に比して政権の中枢で大きな地位を占めているとはいえなかった。
English: Because of this, they had complaints about people like Mitsunari ISHIDA who did not make many contributions in the battle fields but became one of the Gobugyo (five major magistrates) and seized power as a civil servant.
Japanese: そのため戦場での功績は少なかったものの、五奉行の一人で文吏として政権中枢で権力を振るっていた石田三成らに対し、不満を持つようになったのである。
English: Although the family first referred to itself as the Arakawa clan, Yasutsugu INA, a grandson of Yasuuji ARAKAWA who had been given a part of Ina County, Shinano Province, by the Seii taishogun (literally, "great general who subdues the barbarians") Yoshihisa ASHIKAGA, called himself Kumazo INA.
Japanese: 初め荒川氏を称してたが、荒川易氏のときに征夷大将軍足利義尚から信濃国伊那郡の一部を与えられ、易氏の孫の伊奈易次の代に伊奈熊蔵と号した。
English: Yasutsugu, having been defeated in a territorial dispute against his uncle Yasumasa and stripped of his residential castle, moved to Mikawa Province and became a vassal of the Matsudaira clan.
Japanese: 易次は叔父の易正との所領争いに敗れて居城を奪われたため、三河国に移り松平氏の家臣となった。
English: Tadamoto INA, Yasutsugu's son, served Hirotada MATSUDAIRA and his son Ieyasu TOKUGAWA, residing at Kojima-jo Castle in Mikawa Province (the present-day Nishio City, Aichi Prefecture).
Japanese: その子伊奈忠基は松平広忠・徳川家康父子に仕えて三河国小島城（現在の愛知県西尾市）を居城とした。
English: When Ieyasu entered the Kanto region, Tadatsugu followed him to become daikangashira (head of Edo-period prefectural governorship (magistrate, bailiff)), the predecessor of Kanto gundai (a magistrate of the Kanto region), playing a leading role in Tokugawa's rule of their Kanto territory.
Japanese: 家康の関東入国に従って代官頭（関東郡代の前身）となり、徳川氏の関東領国支配の中心的役割を担った。
English: Subsequently, Tadatsugu, as a fudai daimyo (a daimyo as hereditary vassal to the Tokugawa family) became the first lord of the Musashikomuro Domain, with his eldest son Tadamasa INA inherited as the second lord.
Japanese: 忠次はその後譜代大名として武蔵小室藩の初代藩主となり、長男の伊奈忠政が2代藩主となった。
English: Although the Ina clan is generally regarded as a branch family of the Ashikaga clan, as mentioned above, it was described as the Fujiwara clan in "Kansei Choshu Shokafu" (a record of the family trees of samurai warriors of the Edo bakufu).
Japanese: 上記のように伊奈氏を足利氏の庶流と見る説が一般的だが、『寛政重修諸家譜』には藤原氏と記載されている。
English: After the death of Hideyoshi TOYOTOMI in 1596, clashes between the Bunchi-ha faction and Kiyomasa KATO, Masanori FUKUSHIMA and others in the Budan-ha faction became more intense.
Japanese: 慶長元年（1596年）の豊臣秀吉死後に加藤清正、福島正則らとの対立が顕在化する。
English: In 1600, when Mitsunari and his followers took up arms against Ieyasu TOKUGAWA, who was a member of the Council of Five Elders, the Budan-ha faction sided with Ieyasu leading to the Battle of Sekigahara.
Japanese: 慶長5年（1600年）には五大老の徳川家康に対し三成方が挙兵し、武断派は家康方に荷担し関ヶ原の戦いに至る。
English: The defeat at Sekigahara ended in the execution of Mitsunari and others, and the system of Five Commissioners of Toyotomi administration disintegrated.
Japanese: 関ヶ原での敗北により三成らは処刑され、豊臣政権の御奉行制は崩壊することとなった。
English: The Shonai Rebellion occurred in 1599 in Shonai, Hyuga Province (the present-day Miyakonojo City, Miyazaki Prefecture and surroundings) between the Shimazu clan and the Ijuin clan, the chief vassal of the Shimazu clan.
Japanese: 庄内の乱（しょうないのらん）は、慶長4年（1599年）に日向国庄内（現在の宮崎県都城市及びその周辺）で起きた、島津氏とその重臣である伊集院氏との争乱である。
English: This rebellion, which was the largest revolt within the Shimazu clan, was eventually resolved through the mediation of Ieyasu TOKUGAWA.
Japanese: この乱は、島津氏家中最大の内乱であり、最終的には徳川家康の仲介により解決に至ったものである。
English: The rebellion is also considered the reason that the Shimazu clan couldn't send a large force to the Battle of Sekigahara, because the rebellion occurred immediately after the Keicho Campaign and just before the Battle of Sekigahara.
Japanese: また、慶長の役直後、関ヶ原の戦い直前の大乱であり、島津氏が関ヶ原の戦いに大軍を送れなかった原因になったともいわれている。
English: On April 4, 1599, Tadamune IJUIN was killed by Tadatsune SHIMAZU's sword at the Fushimi Shimazu residence.
Japanese: 慶長4年（1599年）3月9日、伏見島津邸に於いて島津忠恒が伊集院忠棟を斬殺した。
English: Tadamune IJUIN was Yoshihisa SHIMAZU's chief vassal and an important follower who worked for the Shimazu clan in the conquest of Kyushu.
Japanese: 伊集院忠棟は、島津義久の筆頭家老であり、島津氏の九州制覇のため活躍した功臣である。
English: When Hideyoshi TOYOTOMI started his conquest of Kyushu, he recognized the difference in military force between the Toyotomi clan and the Shimazu clan and therefore recommended an early surrender.
Japanese: 豊臣秀吉の九州征伐の際は、豊臣氏と島津氏の兵力の違いを認識し早期降伏を主張した。
English: After the surrender, he made himself a hostage and went to Kyoto for post-war activities; that contributed to the continuance of the Shimazu clan.
Japanese: 降伏後は自ら人質となり上洛し戦後処理にあたり、島津氏の存続に貢献した。
English: Therefore, he was recognized as the major vassal of the Shimazu family, and received one county directly from Hideyoshi as part of the post-war treatment.
Japanese: そのため、島津家の代表的家臣と認められ、戦後処分でも秀吉から直接肝属郡一郡を拝領した。
English: In 1594, a survey was conducted within the Shimazu family territory, and the Ijuin clan received Miyakonojo, the land worthwhile 80,000 koku of rice, with a certificate from Hideyoshi TOYOTOMI.
Japanese: 文禄3年（1594年）、島津家領内で検地が行われると、伊集院氏は豊臣秀吉から朱印をもって都城8万石を給された。
English: The Hokugo clan originally held Miyakonojo, but since Tadayoshi HOKUGO was underage and there weren't enough soldiers for the invasion of Korea, the clan was transferred to Kedoin and the size of its territory was reduced to 37,000 from 69,000 koku.
Japanese: それまで都城を領していた北郷氏は北郷忠能が幼少であったことと、朝鮮出兵で軍役の不足があったこともあり、祁答院へ移され石高も6万9千石から3万7千石へ減らされた。
English: Tadamune received direct orders from Hideyoshi and became the manager for the enfeoffment distribution after the survey.
Japanese: また、忠棟は秀吉から直接命令を受け、検地後の知行配分の責任者となった。
English: Consequently, discontent within the Shimazu family was concentrated on Tadamune and he was called the 'flatterer, crafty person' who was disturbing the Shimazu family.
Japanese: このため家中の不満は忠棟に集中し、家中を乱す「佞人」であるとも呼ばれた。
English: Tadatsune SHIMAZU was the third son of Yoshihiro SHIMAZU, who was a younger brother of Yoshihisa SHIMAZU, the head of the main family of the Shimazu clan.
Japanese: 島津忠恒は、島津氏宗家当主、島津義久の弟である島津義弘の三男であった。
English: Because Yoshihisa had no sons and Tadatsune's elder brothers Tsurujumaru and Hisayasu died young, he married Yoshihisa's third daughter, Kameju, and became a successor as the head of the Shimazu clan.
Japanese: 義久に男子無く、また、忠恒の兄（鶴寿丸・島津久保）が若くして死去したため、義久の三女である亀寿と結婚し、島津氏宗家の後継者となった。
English: According to Nisshu Shonai Gunki, there is an entry stating that Mitsunari ISHIDA or Ieyasu TOKUGAWA told Tadatsune, who had returned from Korea after the death of Hideyoshi TOYOTOMI, that Tadamune IJUIN was thinking of rebellion, but there is no other historical evidence of the same era to prove it.
Japanese: 豊臣秀吉の死後、朝鮮から帰国した忠恒に石田三成もしくは徳川家康が伊集院忠棟に叛意があることを伝えたという日州庄内軍記の記述があるが、それを裏付ける同時代史料はない。
English: As the successor to the head of the Shimazu clan, Tadamune IJUIN recommended Yoshihisa's second daughter Shinjo's husband, Akihisa SHIMAZU; that might be another reason for Tadatsune to hate Tadamune.
Japanese: 島津氏宗家相続の際、伊集院忠棟は義久の次女である新城の婿、島津彰久を推奨しており、忠恒にとって忠棟は憎悪の対象であったといえる。
English: Moreover, the domain failed in sending sufficient supplies to the troops that Tadatsune led during the Korean invasion.
Japanese: また、朝鮮の役で出陣した忠恒らの遠征軍に対して、国元からの補給が満足に行われなかった。
English: Tadamune didn't go to Korea, so he was blamed for the insufficient supplies for Tadatsune and was borne a grudge against by the other vassals of the Shimazu clan.
Japanese: 忠棟は朝鮮に出陣しておらず、忠恒らは補給不足の原因が忠棟にあると考えていたことなどもあり島津氏家臣からも深く恨まれていた。
English: Therefore, Tadatsune called Tadamune during the absence of Yoshihisa and Yoshihiro, and killed him.
Japanese: そこで忠恒は、義久、義弘の留守中に忠棟を呼び出し斬殺に到ったものである。
English: Although he was a vassal of the Shimazu clan, the act of killing Tadamune, who had been given Miyakonojo, the land worthwhile 80,000 koku of rice, with a certificate, could have been taken as an act of treason against the central government.
Japanese: 島津氏の家臣であるとはいえ、朱印をもって都城8万石を給されている忠棟を殺害したことは、中央政権に対する反逆ともとれる行為である。
English: Ieyasu TOKUGAWA, who held the real political power at that time, supported Tadatsune's actions by approving a lord's punishing his vassal who rebelled, and as a result, Tadatsune returned to the Shimazu residence.
Japanese: 当時実権を握っていた徳川家康は、主君は反逆した家臣を成敗できるとして忠恒の行為を支持し、その結果忠恒は島津邸へ戻った。
English: Yoshihisa explained to Mitsunari ISHIDA that Takamune's assassination was solely Tadatsune's decision and he was not involved in any way.
Japanese: 義久は、忠棟殺害は忠恒の独断によるものであり、自分は全く関与していないと石田三成に弁明している。
