Featured Shoji Hamada? Help with identifying this vase and mark please.

I have this huge lump of Japanese looking studio pottery very much in the Hamada style but have not seen this shape. It’s wax resist tenmoku glazed and I think the mark is Japanese but it’s extremely difficult to read. Any help would be great. Measures 31cm tall. Thanks.

 

Here are marks used by Shoji Hamada for comparison -

According to this potter, Hamada did not sign his pots -

But there are a number of students and descendants, Japanese and non-Japanese, who have worked in Hamada's style.

 

Nice piece.
