Bonsai pot with Katakana symbols - Can somebody identify this pot?

[ShimpakuBonsai]

Recently I started to try to identify my bonsai pots which have artist marks.
I'm using the Japanese Bonsai Pot Blog as a reference but I can't find anything which looks like it.

I have a square blue glazed pot (10x10x5.5cm) with what looks like to be 4 Katakana symbols on the bottom of the pot.
To my best knowledge the Katakana symbols are: キセワト




Can somebody identify this pot?
Thanks in advance for your help.

It is most likely キク and セト, Kiku being the company name and Seto being the city it was made. Unfortunately, Kiku is a common name and hard to search.
It is Japanese and slip-cast.

It is a mass produced slip pot. Clay, glaze and shape are typical of production bonsai pots. Kiku is (or was--don't know if they're still around) a maker of bonsai tools based in China, so this might be associated with them.

Thanks for the help guys.

I know the name Kiku as a bonsai tool brand but I've never read anything about Kiku bonsai pots.
