Unyso is a small-ish store with only three long aisles located at the busy Chatswood shopping strip. It might sound like 'Daiso' but apart from being Japanese (which translates to high quality products), what they sell is only a part similar.
Unlike Daiso, the prices vary accordingly, and they do not just sell homewares and stationeries, but also food products more than mere snacks as well as condiments, all made in Japan. The products are priced at a relatively expensive price points (as I would have come to know afterwards) but some items are quite unique you would have to make extra efford to find them elsewhere.
The aisles are clearly laid out and feels very neat and clean, it feels a breeze shopping in here.
When you shop there, you are given reusable fabric shopping bag which is quite nice. I could not see any staff apart from the cash register, though.
