I do not speak or read Japanese but there are a couple of sites that may help !! The one above has a pretty comprehensive list !! Although matching the mark may be difficult !! One wrong line can change the meaning !! Have you thought about taking it to a Japanese restaurant or market and ask them to translate it for you ??
Another easier to use site is www.gotheborg.com !! You may try sending them a pic and ask them what it is !!
