adverb, noun which may take the genitive case particle 'no'
Describes doing something in the same manner as always, without change. Often used adverbially or with の to modify a noun.
彼は普段通り、朝6時に起きた。
He woke up at 6 a.m. as usual.
普段通りの生活に戻りたい。
I want to return to my normal life.
Almost synonymous, but 普段通り emphasizes the habitual state, while いつも通り is more colloquial and can refer to a specific repeated action.
Compound of 普段 (ふだん, 'usual, ordinary') and 通り (どおり, 'as, in accordance with').
