What it means
にしても expresses concession: even if something is the case, or even though it is the case, the result or judgment in the main clause still applies. It can present a condition that the speaker accepts for the sake of argument, or acknowledge an unfavorable fact without changing the conclusion. With a noun or a na-adjective, it usually attaches directly to the noun or adjective stem; with verbs and i-adjectives, it follows the plain form. The construction is neutral in register, so politeness is normally shown in the main clause rather than by changing にしても itself.
Usage note
Do not confuse にしても with にしては. にしても means “even if” or “even though,” while にしては means “considering” or “for.” With a noun, にしても can also mean “even for” or “even as for,” depending on context.
