tenkyotodoke wo teisyutusuru.

It is read:

てんきょとどけ を ていしゅつする

A few notes:

• 転居届 = てんきょとどけ
• を = o (written wo in romanization, but pronounced o)
• 提出する = ていしゅつする

届 here means a notification, report, or official notice that you file with an office or government agency.

In this kind of compound noun, 届 is read とどけ.

So 転居届 literally means something like:

• moving-residence notification
• in natural English, change-of-address notice or moving notice

を marks the direct object of the verb.

So in 転居届を提出する:

• 転居届 = the document
• を = marks it as the thing being acted on
• 提出する = to submit

So the structure is basically:

[document] + を + [submit]

提出する is more formal and is commonly used for documents, forms, assignments, and official paperwork.

So it fits very well with 転居届, which is an official notice.

Compare:

• 転居届を提出する = formal, official-sounding, good for documents and administrative language
• 転居届を出す = more everyday and conversational

Both can be understood, but 提出する sounds more appropriate in bureaucratic or written contexts.

Yes. In Japanese, the subject is often omitted when it is obvious from context.

So 転居届を提出する。 can work as a complete sentence, especially in contexts like:

• instructions
• checklists
• manuals
• headings
• administrative guidance

Depending on context, the omitted subject could mean:

• I submit a change-of-address notice
• You should submit a change-of-address notice
• Submit a change-of-address notice

Japanese often leaves that unstated.

The dictionary form can do several jobs in Japanese. Here, it most likely has one of these uses:

• a neutral statement: submit a change-of-address notice
• a checklist/to-do item: to submit a change-of-address notice
• an instruction in a concise style: submit a change-of-address notice

So even though it is not explicitly saying please, the plain dictionary form is very common in written instructions and labels.

If you wanted to make it more directly polite, you could say:

• 転居届を提出してください。 = Please submit a change-of-address notice.

Not exactly. In Japanese administrative usage, 転居届 usually refers to a notice that you file when you move within the same municipality.

For example:

• moving to a different address within the same city/ward/town/village → 転居届

If you move from one municipality to another, different terms are often used:

• 転出届 = notice of moving out
• 転入届 = notice of moving in

So 転居届 is a specific official term, not just any casual word for moving.

Japanese often makes compact compound nouns by putting nouns together directly.

So:

• 転居 = moving residence / change of residence
• 届 = notice / notification

These combine into the fixed compound:

転居届

Using の is not the normal way to name this official document. Official document names are often very compact like this.

So 転居届 sounds like the proper document title, while 転居の届 would sound less natural in this context.

Yes. That would be a polite form and is very natural if you are speaking about your own action.

Compare:

• 転居届を提出する。 = plain form; dictionary style; often used in writing, lists, or neutral statements
• 転居届を提出します。 = polite spoken/written statement: I will submit / submit a change-of-address notice
• 転居届を提出してください。 = polite request: Please submit a change-of-address notice

So the best choice depends on the situation.
