4 great places to buy furniture and home goods in Japan

Nitori - Nitori is a home goods and furniture store in Japan with thousands of branches across Japan. Unless you're living in a particularly remote area it's likely you'll have a store nearby! But they also have their own web shop so if there isn't one nearby it's not a problem. Nitori is known for it's decent quality whilst being super cheap. They deliver most items and they also have a service where they can set up most items for you too. They have plenty of designs to choose from and their products are fashionable. 

Amazon - Need anything? Well it's likely you can find it on amazon. They have their own huge selection of goods as well as independent shops on their market place so you're always spoiled for choice. Of course this means you can order pretty much anything but without a physical store you're not going to see the item before it arrives. There's also the issue of if you're ordering a bunch of different stuff from different marketplace stores it's all going to be delivered separately. Their customer service is usually reasonably good at dealing with issues though.

Ikea - The Swedish furniture overlords. There are a few branches across Japan, but they also have their online store. Again they're known for being affordable and also fairly sturdy like Nitori. The only downside is you'll have to assemble everything yourself so if you're living alone you might need to call a friend to come and help.

Rakuten - Similar to amazon but its completely marketplace stores so you might have the issue of several different orders from different stores and organising/arranging the deliveries. There is a huge amount of choice in the large furniture department compared to amazon, however their customer service relies entirely on the store you're dealing with.
