The process for applying for a visa can be long and arduous. Thankfully Sendai has some top notch immigration lawyers who can help you out. Here is the link to the Sendai immigration office but we highly recommend hiring a professional. For a normal sized family you can expect to pay between $3000 to $5000 for the whole process up to issuance of your resident card.
Based on our experience we recommend Sendai Forest Visa and Law for all of your immigration visa needs. Their website can be read in English and they can converse in English as well.

The small building is easy to find and there is plenty of parking. You will need to speak Japanese or bring a friend as none of the immigration officers speak English. Again, we recommend you hire a lawyer to manage most of your interactions with this department. For much more information visit this LINK.
