It was confirmed this past week by a good friend of Kazue, that her husband is Tom of Toy & Goods Trading. That shop appears to be up and running.
Please note, if you order from them that they accept only Paypal. Do not pay with a balance, pay with a credit card through Paypal. That way even if Paypal denies your claim (if you have to make one) you can always turn to your credit card company and do a chargeback. Paypal hates that but you are protected.
I thought it was very, very strange that no one except the person who confirmed the information to collectors knew this. It's rather unusual for a husband and wife to have very similar but separate businesses in the same area. Perhaps Kazue was trying to prove to Tom that she could do it better.
Some who regularly order from T&G Trading are understandably concerned that he might go under as well. All I can say is that if you have a major credit card, use it through Paypal. Get all your funds out of your account before ordering and use as your back up funding source a credit card - not a bank account.
Tom has the prettiest duo for sale. They are "Good Morning Amelie" and "Good Night Misaki" from the Secret Code Collection. His price is 32,600 yen for the set. That's $403.31 USD; 244.59 British Pounds; or 270.50 Euros. They are also available separately but they look so pretty together.
