Japanese teapot, modern Arita style

I would like to identify the mark of this teapot.
It is blue and white Arita style, hand painted including the mark.
I found it in a thrift shop, I took it because it is nicely painted despite it look me brand new.
I tried searching in the recent Arita production marks, but nothing of similar.



Probably some Member that can read Japanese (or Chinese?) can help me.

Thank you.

I think it is relatively new. Unfortunately I don't read Kanji but you may find the mark on the Gotheborg.com website which has lists of many of the 20thC Chinese and Japanese Ceramics marks.

Thank you Naomi.
