It’s always bothered me how few merchants are willing to ship their goods worldwide. If the customer is willing to pay for the shipping and customs costs, why should they be denied? Unfortunately, the vast majority of Japan and U.S. based companies hold to this “not outside our borders” policy.
These Japanese-food-goods oriented companies do, however, ship worldwide. Good for them! Often you’ll find that their prices are not that different from what you might pay for similar goods shipped within the country you reside. And for people who live in parts of the world without a lot of Japanese-oriented businesses, they are saviors.

Sites that I’ve tried myself are marked with a (maki).
These mailorder stores carry a wide variety of products, edible and otherwise.

These companies act as your ‘friend who lives in Japan’, for a fee of course. You have things shipped to them from merchants who don’t ship overseas, which they will then send it to you. The commission is usually around 10%, but it pays to compare their service fee structures (some require a flat service fee on top of the percentage.)
Tenso  seems to be the most active shipping service at the moment. They are advertising heavily on Google Adsense and such (you may see their ads pop up on these pages), and they seem to be the recommended shipping service of Rakuten. Their web site is in English, Japanese, Mandarin and Cantonese. They charge a 10% fee for receiving and shipping your package to you. They can also consolidate multiple package for you before shipping them out to you, for an additional fee. Comments: I’ve used them a couple of times, and they are quite reliable. (maki)

Comments: “I use i-tm4u for anything I want to buy from Japan, especially when the company does not ship OS. I’ve bought a few Bento boxes as well as other non Bento items through them and they have always been well packaged and arrive quickly. Their commission is low and shipping is very reasonable.” -(Becki)
“Today i received my work-of-art lunchbox and can say that i-TM4U […] is a very good and reliable shopping agent. It is very difficult to communicate with Japanese companies in English so i was glad to rely on their help with payment, shipping etc. i-TM4U was very accurate with all the info, the box was very well packed as i asked and the pricing is reasonable, too.” -(Anna from Russia)
