A privately run, small shop—usually family- or owner-operated rather than part of a large chain (a 'mom-and-pop' store).
この通りには昔ながらの個人商店がたくさん残っている。
There are still many traditional mom-and-pop shops left on this street.
個人商店は大手よりも融通が利くことが多い。
Small private shops are often more flexible than big companies.
休日は地元の個人商店で買い物をするのが好きだ。
I like shopping at local independent shops on my days off.
