としても details
Examples
even supposing; even if we take it that — concedes a constructed hypothesis and insists the outcome holds regardless
今から急いだとしても、終電には間に合わないよ。
ima kara isoida to shitemo, shuuden ni wa maniawanai yo.
Even supposing we hurry now, we won't make the last train. casual
この案が正しいとしても、予算が足りなければ実行できない。
kono an ga tadashii to shitemo, yosan ga tarinakereba jikkou dekinai.
Even supposing this proposal is correct, we can't carry it out if the budget falls short. neutral
仮に交渉が不調に終わったとしても、次の対応を今から検討しておくべきだ。
kari ni koushou ga fuchou ni owatta to shitemo, tsugi no taiou o ima kara kentou shite oku beki da.
Even supposing the negotiations end in failure, we should be considering our next response from now. formal
Formation
plain clause + としても（Nだとしても）attaches to plain clause
Notes
automatic-consequence と of 押すと — としても always concedes something
the speaker set up for argument's sake, never a lawlike trigger.
Related patterns
Similar
ても concedes an actual or plain hypothetical situation directly with no overt framing; としても explicitly marks the clause as a constructed SUPPOSITION via とする, reading more argumentative and at home in written discussion — 高[たか]くても買[か]う concedes a plain fact, 高[たか]いとしても買[か]う concedes a deliberately set-up hypothesis.
Both add とする to mark an overt, constructed supposition, but としたら threads into a CONDITIONAL continuation (if X, then Y follows — 予算[よさん]が足[た]りないとしたら、どうする？), while としても threads into a CONCESSION (even if X, Y still doesn't change — 予算[よさん]が足[た]りないとしても、進[すす]めるべきだ) — same hypothesis frame, opposite logical connective riding on it.
Lookalikes
Same と＿＿＿ても shell, differing only in the middle — と言っても concedes what's just been SAID or granted in words ("granting that," と言[い]っても言[い]い過[す]ぎだ), while としても concedes a constructed SUPPOSITION set up via する; skimming past 言う vs する at reading speed is an easy miss inside an otherwise identical frame.
One kana apart (に／と) and routinely misread as free variants — としても grants a single hypothetical case ("if it were so", お金[かね]があったとしても), while にしても enumerates real cases side by side (子供[こども]にしても大人[おとな]にしても) — swapping one for the other in a list of real alternatives vs. a lone granted hypothetical reads oddly even though both gloss "even if/granting".
