Renaissance Playest: Japan Late 16th Century

I've just completed an excellent Renaissance game which simulated a clan dispute set in Late Feudal Japan c.1550 to 1600. Clan Yakato was opposed by Clan Onaka with the battle set in a lightly wooded valley. Both sides had roughly the same composition of troop types: Clan Yakato Samurai (Gendarmes, Extra Heavy Armour, Elite) 2 Samurai (Swordsmen, Heavy Armour, Elite) 1 Samurai (Swordsmen (Longbow), Heavy Armour, Elite) 1 Ashigaru Mixed Unit: 2 x Shot (arquebus), Medium Armour, Average 2 x Pikemen (spears), Medium Armour, Average 3 Wakato (Light Infantry (longbow), Light Armour, Average)1 Clan Onaka Samurai (Gendarmes, Extra Heavy Armour, Elite) 1 Samurai (Swordsmen, Heavy Armour, Elite) 1 Samurai (Swordsmen (Longbow), Heavy Armour, Elite) 1 Ashigaru Mixed Unit: 2 x Shot (arquebus), Medium Armour, Average 2 x Pikemen (spears), Medium Armour, Average 4 Wakato (Light Infantry (longbow), Light Armour, Average)1 Chugen One of the Ashigaru units designated as Elite Infantry units were composed of only four stands. This is in contravention of the Renaissance Rules, however, I felt that infantry formations were probably smaller than their European counterparts and this also increased the power of Samurai cavalry in relation to dismounted units, something I wanted to simulate. For aesthetics I represented every unit with 6 stands ranged 3 to front 3 to rear. As in my other games that I've used this method, the fifth and sixth were for visual purposes only with no impact on gameplay apart from bulking the unit during the process of casualty attrition. The game proved to be a real epic. It began well for Yakato and by turn 6 it looked as though they had the battle in the bag, however, a quite phenomenal revival of fortunes by Onaka Clan, showing a real Bushido spirit, kept their hopes alive all the way to end of Turn 15 when they were finally reduced to two units, leaving Yakato the bruised victors with five remaining functioning formations. Again I used the D20 casualty removal and the Charge Test solo amendment. All of these worked fine, introducing a few raised eyebrows when my elite Onaka Samurai Swordsmen refused to charge a waiting unit of Ashigaru. I'm starting to write up some Battle Reports so I'm hoping, in time, to post these with diagrams to the Files Section.
