★★★★★

I asked them to handle the Certificate of Eligibility and renewal application for a Specified Skilled Worker visa. Communication was efficient, and the explanation of the documents I needed to prepare was clear. They handled everything very carefully, and the procedures for the foreign national were completed successfully. I can highly recommend this administrative scrivener.

★★★★★

They helped me with document translation and obtaining an apostille. Their work and communication were both prompt and accurate, and their handling of overseas shipping was extremely helpful.

★★★★★

I asked them twice to obtain embassy consular authentication for an application for Malaysia’s “Second Guardian Visa.” I also requested translation. Compared with other offices, their fee was reasonable and their service was careful. For the second request, despite my sudden request, they responded as quickly and carefully as possible with expedited service. I cannot thank them enough.

★★★★★

After being transferred to Panama, I needed apostille procedures in Japan for a document required by the local Ministry of Education: a certificate issued by the international school my child had attended in Japan. In addition to communicating with the international school and about the letter of attorney, they carefully handled changes to the document’s contents and the signatory. The procedures were completed successfully. They shared progress updates promptly, so I was able to entrust the work to them with confidence.

★★★★★

I visited for a consultation about citizenship and permanent residency. They answered my questions very gently and carefully, resolving my various concerns and putting me at ease. There are honestly few offices knowledgeable about international matters, so Mr. Sato’s expertise is extremely valuable and appreciated. I believe I can entrust work to this office with confidence.

★★★★★

Thank you very much for all your help. Their responses were clear and their service was careful, so I was able to leave everything to them with confidence. I am glad I asked Mr. Sato. If I have another opportunity, I would definitely ask again. Thank you very much.

The best administrative scrivener. They have helped me with many things. I look forward to continuing to work with them.

★★★★★

Thank you for responding promptly and carefully, even during the Obon holiday period. I was able to entrust the matter to them with confidence even from overseas. Thank you very much.

“Is life overseas more fulfilling than life in Japan? The number of Japanese permanent residents overseas reaches a record 580,000; tax savings and children’s education are among the reasons, and 20% of affluent people say they are considering it for the future.”

Message from the Representative

English reference translation of Taiga Sato's administrative scrivener registration certificate, registration number 19080406, registered February 15, 2019

Taiga Sato · Registration No. 19080406. Certificate shown with an English translation for reference.

Hello.
My name is Taiga Sato, and I am an administrative scrivener.

Thank you for visiting our website.
On behalf of busy clients, we provide prompt assistance in obtaining apostilles and consular authentication.

Our office is located in Minato-ku, Tokyo, where many foreign embassies are concentrated, so travel time to the Ministry of Foreign Affairs, notary offices and embassies in Japan is reduced.
This enables us to complete urgent procedures for our clients promptly.

Our clients include individuals planning to leave Japan to study or work abroad, doctors living overseas, large companies such as listed companies, and small and medium-sized businesses.

We also hold a DHL export account, enabling the smooth overseas shipment of documents.

Apostille and consular-authentication procedures can involve an enormous amount of time and rework when you are unfamiliar with them.

Speed is important, but careful double-checking is essential. We have seen cases in which a person’s name was spelled incorrectly on an important document, requiring enormous time and additional expense to correct.

If you have any concerns, please feel free to contact us.

Taiga Sato, Certified Administrative Scrivener
