The largest Japanese black font across the top is just the company name: Almit
The small Japanese white font across the bottom just reads: Japan Almit Corporation
The white font on the right-hand side, which is probably the most important has the product number/grade, but also reads: yani-nashi or yani-free. I have no idea what yani is...Lead maybe, but that's just a guess.
I would search the web for Almit Corporation, and search for that product number.
Good Luck
