I realized I needed help when I was spending more and more time keeping track of expenses and dealing with Japanese bureaucracy headaches (trying to figure out how deductions work, etc.) rather than focusing on my craft, which is writing books!... Having to deal directly with filling my tax return at the end of the year has always been a big stress for me. Now the process is pain free thanks to OAO! It saves me time. A lot of time! And you know what they say, time is money. They provide frictionless service and are easy to communicate with. They care about me and my money. Working with OAO will remove all your headaches about taxes! Less headaches, more happiness.

Coming to Japan as a Berlin creative wasn’t esay at all. Things have to be in line 100% of the time. Otani-San took care of these things for me. Every time I leave their office I feel very relieved and secure. My creative chaos found a safe space in their office and I am very thankful for that.

I ended up taking the services of the Otani Accounting Office because their website was great and they had good reviews online.

The OAO team was with me every step of the way, offering advice and tips to make my future tax returns even easier.

As a result, I got a fantastic return, claiming the amounts that I was entitled to.”
