I've managed to damage Takeda through a war of attrition but unfortunately this weakening of Takeda (he's still strong though) has lead to Hojo capturing most of the map so even if I manage to finally break Takeda I'm going to get slaughtered by Hojo.
I think my mistakes were:
1) Not taking Sado early
2) Relying on trade partners who were neighbours
3) Not investigating far flung trade opportunities
4) Treating the diplomacy as it was in past TW games
As I have said elsewhere on the forum, my belief is that if you are relying on a neighbour (say Takeda) strongly to support your armies for an invasion elsewhere, they will let you build up and then pull the rug out from under you by breaking the trade agreement just as you are ready to attack. This wrecks your economy forcing you to downsize your army and threatens your borders forcing you to stop expansion and concentrate on defence.
The only reason I survived the initial betrayal was that I risked public disorder and just took my armies on an immediate pre-emptive strike on the Takeda border regions. This allowed me to stabilise my economy to an extent and keep most of my army (not to mention the fact that I killed Takeda Shingen, his son and a couple of generals in an epic battle).
Outcome of this effort? I'm at a stale mate with heavy losses on both sides and have been for years with no hope of declaring peace.
