Need help identifying make of whole plate film holder

[Simon Benton]

I bought 5 whole plate film holders that were supposed to be for the Rittreck View. Two of them fit the Rittreck but the other 3 are a bit larger. The only mark I could find on them is shown below. Can anyone help identify the mark and which camera they might fit.?

The Japanese katakana characters (you have it upside down!) say "Hasemi".
