Shops in the first 3 days of the new year

This new year is very cold.

I went to 100yen shop to buy some stuff. But! It was closed although I came in the cold. Oops!

I saw the web site of the shop to check before going there whether it has already opened, but there was no information about that.

When I was a kid, most of the shops and restaurants were closed in the first 3 days of the new year. But recently, many of them open from 2nd, some of them open even from 1st. So I took it for granted that the 100yen shop opened. According to a sign displayed on the shop's door, it will open from 4th. Hmm... Too late for recent trend.
