Communication was very smooth and service was very prompt.


R.C.様(USA, Refund of withholding tax from lump-sum withdrawal payment claim)

Great service. Got the refund of my withholding tax promptly. They were also always fast to respond to my emails. I’ve recommended Cazasa to my friends in Japan and would have no reservation doing so again.

Prompt service.


H.Z.様(Canada, Tax filing agency service)

It was such a pleasure to be under your care. If there is anyone ever in need of tax services in my type of situation please allow me to refer them to you.


Valued Customer様

Masuda-san was always well-informed, quick to respond, and extremely helpful to ensure I received all of my refunds after leaving Japan.


Valued Customer様

Thank you for the timely support and excellent service especially since I had to leave Japan in a short notice and due to Japanese language for official communication. Would also be happy to refer you to my colleagues in Japan if they need tax related consultation.
