The comparison requires separating organization, technology, logistics, manpower quality, tactics, and strategic reach. Using the Imjin War (1592–1598) and Joseon–Chongyu (Chongju?)—interpreted as campaigns around the same conflict—and broader Sengoku-era and late-Ming evidence yields a nuanced picture: Ming and Japanese forces were differently optimized. Japan’s armies were superior in offensive cohesion, battlefield aggression, and infantry marksmanship for the short, fast campaigns typical of Sengoku warfare; Ming forces were stronger in scale, fortified defense, artillery, and combined operations when properly supplied and commanded, but suffered chronic command, quality-control, and logistical problems that undercut those advantages.
对两者的比较需从编制、技术、后勤、兵员素质、战术及战略投送能力等方面展开。通过壬辰战争（1592-1598年）、朝鲜王朝的忠州战役（此处“Chongyu”暂解读为“Chongju”，即忠州战役，可视作同一冲突背景下的作战行动），结合日本战国时代及明末更广泛的史料可知，明、日军队各有优势侧重：对于日本战国时期典型的速战速决式短期战役，日军在进攻协同、战场主动性及步兵射击精度上更具优势；明军若补给充足、指挥得当，则在规模、防御工事、火炮装备及联合作战方面实力更强，但长期存在的指挥混乱、质量管控缺失及后勤问题，削弱了这些优势。

1) Organization and command
1. 编制与指挥
- Japanese (Sengoku)
- 日本（战国时期）
- Feudal but increasingly centralized under daimyo: clear chain within a clan, high discipline among retainers.
- 虽为封建制，但在大名统治下中央集权程度不断提升：家族内部指挥体系清晰，家臣纪律性强。
- Modular units (ashigaru, samurai) trained for combined massed arquebus volleys and close combat; daimyō exercised unified command in campaigns.
- 模块化部队（足轻、武士）经训练可协同实施火绳枪齐射与近战；大名在战役中拥有统一指挥权。
- Flexible command doctrine favoring rapid, decisive offensives and concentrate forces for single obxtives.
- 指挥理念灵活，倾向于快速、果断的进攻，并集中兵力达成单一作战目标。
- Ming
- 明朝
- Professional bureaucracy: provincial garrisons, hereditary military households eroded by the 16th century.
- 实行专业官僚体系：设有地方卫所，但到16世纪时，世袭军户制度已逐渐瓦解。
- Fragmented command between central court, regional jin (provincial) commanders, and semi-autonomous generals; political interference common.
- 指挥权分散于中央朝廷、地方总兵及半自治将领之间；政治干预现象普遍。
- Formal unit types (weiguo, tent-mounted cavalry, gun brigades) existed but coordination between provincial troops, Green Standard, and new recruits was uneven.
- 虽有正规部队编制（如卫所兵、营兵骑兵、火器营），但地方军队、绿营兵与新兵之间的协同能力参差不齐。

2) Training, morale, and troop quality
2. 训练、士气与兵员素质
- Japanese
- 日本
- Samurai core with high training; ashigaru increasingly drilled in musketry and unit tactics after mid-16th century.
- 以训练有素的武士为核心；16世纪中期后，足轻也逐渐接受火绳枪操作与战术配合训练。
- High motivation in daimyo-led campaigns; cohesive social military culture.
- 在大名率领的战役中，士兵战斗积极性高；拥有凝聚力强的军事社会文化。
- Ming
- 明朝
- Professional soldiers existed but many units were poorly trained or underpaid; mercenary and militia supplementation common.
- 虽有职业士兵，但许多部队训练不足或军饷微薄；频繁依赖雇佣兵与民兵补充兵力。
- Desertion and low morale frequent when logistics and pay failed; elite Ming units (like better artillery crews or veteran contingents) performed well when present.
- 当后勤补给中断、军饷拖欠时，逃兵现象频发且士气低落；但明朝精锐部队（如训练精良的炮兵班或老兵部队）若投入作战，表现通常出色。

3) Firearms, armor, and battlefield tactics
3. 火器、铠甲与战场战术
- Firearms
- 火器
- Japan: mass deployment of arquebuses (tanegashima) by late 16th century; disciplined volley fire, use of rotating ranks, combined with shock samurai attacks.
- 日本：16世纪末期已大规模装备火绳枪（“铁炮”）；战术上注重有纪律的齐射、轮射，并结合武士的冲击战术。
- Ming: early and extensive adoption of gunpowder weapons—matchlocks, cannons, petards, mines—but doctrinal integration varied. Ming artillery (field and siege) and naval cannon were technically advanced.
- 明朝：较早且广泛使用火药武器，包括火绳枪、火炮、炸药包、地雷等，但这些武器在战术体系中的整合程度不一。明朝的野战炮、攻城炮及舰炮在技术上较为先进。
- Armor and melee
- 铠甲与近战
- Japanese combined arquebus volleys with yari (pike) and samurai shock tactics; armor lighter for mobility.
- 日军将火绳枪齐射与长枪（“枪”）战术、武士冲击战术相结合；铠甲更轻便，以提升机动性。
- Ming cavalry and infantry retained more classical armor types; Chinese emphasis on missile and artillery support in siege contexts.
- 明朝骑兵与步兵仍沿用较多传统形制的铠甲；在攻城战中，明军更注重弓弩与火炮的火力支援。

4) Logistics and strategic depth
4. 后勤与战略纵深
- Ming advantages
- 明朝优势
- Larger fiscal and demographic base; capacity to muster tens of thousands of troops, naval resources, and siege trains.
- 财政与人口基数更大，能够征召数万兵力，调动海军资源及攻城装备。
- Established granary and supply systems in theory; ability to replace losses long-term.
- 理论上拥有完善的粮仓与补给体系；具备长期补充兵力损耗的能力。
- Ming limitations
- 明朝劣势
- Corrupt administration, delayed pay, poor requisitioning often undermined field armies. Long internal lines and bureaucratic delays hindered rapid concentration.
- 行政腐败、军饷拖欠、物资征调不力等问题常削弱野战部队实力。漫长的国内补给线与官僚体系的低效，阻碍了兵力的快速集结。
- Japanese
- 日本
- Excellent short-range logistics and campaign discipline under a daimyo; superior at rapid sustained campaigning in Korea initially due to compact command and motivated cadre.
- 在大名统领下，短途后勤保障出色且部队作战纪律严明；初期在朝鲜战场，凭借精简的指挥体系与积极性高的骨干力量，擅长开展快速持续作战。
- Limited strategic depth for protracted continental war; inability to rebuild massive losses without central national bureaucracy.
- 缺乏支撑长期大陆战争的战略纵深；因无全国性中央官僚体系，难以弥补大规模兵力损耗。

5) Siegecraft and engineering
5. 攻城战术与工程技术
- Ming strength: superior siege artillery, mining, and fortification doctrine; skilled use of cannons, rams, and coordinated sieges. Ming engineers and specialist artillery units could reduce fortifications systematically.
- 明朝优势：攻城火炮、坑道挖掘技术及防御工事建造理念更先进；善于运用火炮、撞锤，并组织协同攻城行动。明朝工兵与专业炮兵部队能够有计划地摧毁防御工事。
- Japanese: competent at storming and blockade, inventive in field engineering, but generally less effective against well-prepared, heavily-gunned fortifications without artillery parity.
- 日本：擅长强攻与封锁战术，在野战工程方面富有创造力，但若缺乏对等的火炮实力，面对防御完备、火力密集的工事时，通常效果有限。

6) Naval power
6. 海军实力
- Ming: experienced navy with large warships (somewhat diminished after mid-1500s but still capable), superior heavy cannon and riverine/sea logistics when committed.
- 明朝：海军经验丰富，拥有大型战舰（16世纪中期后规模略有缩减，但仍具备战斗力）；若全力投入，重型舰炮性能及内河与海上后勤保障能力更具优势。
- Japan: coastal fleets and strong small-ship capabilities; used transports effectively in Imjin War but lacked heavy naval artillery comparable to Ming treasure fleets. Korean navy (Joseon) superiority in coastal warfare also affected dynamics.
- 日本：拥有沿海舰队，小型舰船作战能力较强；壬辰战争中成功运用运输船，但缺乏能与明朝郑和宝船级别的重型舰炮。朝鲜王朝海军在近岸作战中的优势，也对战场态势产生了影响。

7) Performance in the Imjin War (1592–1598) — direct evidence
7. 壬辰战争（1592-1598年）中的表现——直接证据
- Initial Japanese successes (rapid capture of Seoul and Pyongyang) showed Japanese tactical superiority: speed, combined arquebus-ashigaru-samurai assaults, excellent logistics for a short campaign.
- 日军初期的胜利（迅速攻占汉城与平壤）体现了其战术优势：进攻速度快，火绳枪兵、足轻与武士协同突击，且短期战役后勤保障出色。
- Ming intervention changed the balance: Ming troops, when competent and adequately led, prevented full Japanese conquest, conducted sieges and field operations, and supported Korean counterattacks. Ming artillery and numbers were decisive in several actions.
- 明朝的介入改变了战局：明军若指挥得力、兵员精锐，便能阻止日军全面征服朝鲜，开展攻城与野战行动，并支援朝鲜反击。在多次战役中，明军的火炮优势与兵力规模起到了决定性作用。
- Key weaknesses revealed: Ming field armies often arrived late, suffered poor coordination with Korean forces, and some Ming contingents were poorly led or supplied. Conversely, Japanese supply lines stretched and attrition, guerilla resistance, naval interdiction, and Korean–Ming cooperation eventually blunted Japanese offensives.
- 双方关键劣势暴露：明朝野战部队常姗姗来迟，与朝鲜军队协同不畅，部分明军部队指挥失当或补给不足；相反，日军补给线逐渐拉长，加上兵力损耗、朝鲜游击队袭扰、海道被切断以及明鲜联军的协同抵抗，最终遏制了日军的进攻势头。
- Overall: Japanese armies were more tactically effective early; Ming strategic depth and material advantages prevented a total Japanese victory once Beijing-oriented obxtives were excluded.
- 总体而言：战争初期日军战术效能更高；但一旦日军放弃以进攻明朝都城北京为目标，明朝的战略纵深与物资优势便足以阻止其获得全面胜利。

8) Theoretical context and systemic differences
8. 理论背景与体系差异
- Military Revolution theory nuance: Japan shows rapid firearm-driven tactical change at unit level (massed arquebuses, volley fire), while Ming displays earlier gunpowder mastery at a strategic and siege level. Ming institutional sclerosis limited doctrinal adaptation; Japan’s state fragmentation produced local innovation and quick tactical learning.
- 军事革命理论视角下的细微差异：日本在部队层面呈现出由火器推动的快速战术变革（大规模火绳枪装备、齐射战术），而明朝则更早地在战略与攻城层面掌握了火药武器的运用。明朝僵化的体制限制了战术理念的革新；日本的分裂状态反而催生了地方层面的创新与快速战术学习。
- Industrial/organizational gap: Ming had greater capacity to mobilize resources (manpower, metallurgical output for artillery) but lacked modern centralized war finance and reforms necessary for long, professionalized expeditionary warfare.
- 工业与组织差距：明朝拥有更强的资源动员能力（人力、火炮所需的冶金产能），但缺乏现代化的中央集权式战争财政体系，也未进行支撑长期专业化远征作战所需的改革。

Conclusions (concise)
结论（简明总结）
Tactical edge: Sengoku Japanese forces had superior offensive cohesion, musket-ashigaru tactics, and short-term campaign effectiveness.
战术优势：日本战国时期的军队在进攻协同、火绳枪-足轻战术及短期战役效能上更具优势。
Strategic/material edge: Ming had superior strategic depth, artillery/siegecraft, and the ability to sustain large-scale campaigns if administration functioned.
战略与物资优势：若行政体系运转正常，明朝拥有更优的战略纵深、火炮/攻城技术，及支撑大规模战役的能力。
Operational reality: In the Imjin War, these strengths and weaknesses played out—initial Japanese tactical dominance was checked by Ming material power and combined Sino-Korean resistance; Ming administrative and logistical failings limited a decisive, clean victory but were sufficient to prevent Japanese conquest.
作战实际情况：壬辰战争中，双方的优劣充分显现——日军初期的战术主导地位被明朝的物资实力与明鲜联军的抵抗所遏制；明朝的行政与后勤缺陷使其无法取得彻底胜利，但已足以阻止日军征服朝鲜。
Comparative summary: Not a simple “better/worse.” Japan excelled at aggressive, innovative battlefield tactics; Ming excelled at scale, artillery and fortification warfare. Outcomes depended on leadership, logistics, and whether the conflict favored rapid offensives or protracted, resource-intensive operations.
对比总结：无法简单判定双方“谁更强”。日本擅长主动、创新的战场战术；明朝则在作战规模、火炮运用及防御工事作战方面更具优势。战争结果取决于指挥水平、后勤保障，以及冲突本身更适合速攻速决，还是需要长期、高资源投入的持久战。

According to historical record (see below Wikipedia post), Japan sent ~160K troops to Korea during the 1st invasion, and ~140K troops during the 2nd invasion. Those troops easily defeated Korean troops and occupied most part of Korea, which demonstrated their strength and capability.
根据史料记载（见下文维基百科内容），日本第一次入侵朝鲜时派遣了约16万兵力，第二次入侵时派遣了约14万兵力。这些日军轻松击败朝鲜军队，占领了朝鲜大部分地区，彰显了其实力与作战能力。
In response, Chinese Ming dynasty sent ~48K troops during the 1st invasion, and ~75K troops during the 2nd invasion. Those Chinese troops defeated Japanese troops in much higher numbers. This proves that Ming army was much stronger than Japanese army.
作为应对，中国明朝在日军第一次入侵时派遣了约4.8万兵力，第二次入侵时派遣了约7.5万兵力。这支明军击败了数量远超自身的日军，这证明明朝军队实力远胜日军。
Japanese army had superior guns obtained from Europeans, but Chinese troops had much more powerful cannons and superior cavalry.
日军拥有从欧洲获取的先进火枪，但明军拥有威力更强的火炮与更精锐的骑兵。

Looking at the records, the Japanese military had better equipment, even to the number of muskets, katana that can cut armor, even the number of people deployed, even on the naval side, Japan has more ships compare to Korean and Ming, Japanese generals were also more battle-hardened, but it seems Japanese supply logistics were run by morons, the supplies were cut numerous times leading to starvation of the main army and the eventual loss of Japan, either that or Yi sun si was a naval genius.
从史料来看，日军装备更精良，无论是火枪数量、可劈砍铠甲的武士刀，还是投入的兵力规模，均占优势；海军方面，日军舰船数量也多于朝鲜与明朝，且日军将领更富实战经验。但日军的后勤补给体系似乎由无能之辈负责，补给线多次被切断，导致主力部队陷入饥荒，最终战败。另一种可能是，李舜臣（Yi Sun-sin）是位海军天才（其指挥的朝鲜海军对日军后勤造成了关键打击）。
