Your First 30 Days Renting in Shinjuku: A Practical Checklist

You have signed the lease and collected the keys. Now the real work begins. The first month in a new Shinjuku apartment is full of small tasks that are easy to forget and annoying to fix later.

This checklist covers what to do, roughly in the order you should do it.

Days 1 to 3: Get the apartment running

• Electricity and water. These are usually already connected or start with a simple online form. Check that the breaker panel is switched on.
• Gas. Gas needs an in-person opening visit. A technician checks the line and turns it on. Book this before you move, or you will have no hot shower on your first night.
• Take photos of everything. Record existing scratches, stains and damage on day one. This protects your deposit when you move out.
• Find the garbage area. Ask the management company or check the notice board for the collection point.

Days 1 to 14: Register your address

Japanese law requires you to register your address at the ward office within 14 days of moving in. For Shinjuku residents, that means the Shinjuku City Office or one of its branch offices.

Bring your residence card and passport. At the same visit you can usually handle:

• National Health Insurance enrollment (if you are not covered by an employer plan)
• National Pension enrollment
• Updating your My Number card address, if you have one

The address on your residence card must match where you live. Many later tasks, from opening a bank account to signing a phone contract, depend on this step.

Week 2: Money and communication

• Bank account. Japan Post Bank and several online banks are common first choices for newcomers. Most require a registered address and a Japanese phone number.
• Phone contract. If you arrived on a temporary SIM, switch to a regular plan now.
• Internet. Fiber installation can take two to four weeks in busy areas. Apply early, or ask whether your building already has internet included. A pocket Wi-Fi rental can bridge the gap.

Week 3: Learn the local rules

Garbage sorting is the rule that trips up most newcomers. Shinjuku separates burnable waste, non-burnable waste, recyclables and bulky items, each with its own collection day. The ward publishes a guide in English. Put trash out on the right morning, in the right bag, and your neighbors will be grateful.

Noise matters too. Many Shinjuku buildings are wood or light steel construction. Avoid laundry, vacuuming and loud calls late at night.

Bicycles must be registered, and parking on the street can get your bike removed. Use your building's bike parking or a paid lot.

Week 4: Explore your neighborhood

Shinjuku is much bigger than its famous station. Once the paperwork is done, get to know the area you actually live in:

• Takadanobaba: student energy, cheap ramen, Waseda University nearby.
• Okubo and Shin-Okubo: Tokyo's Koreatown, with international grocery stores.
• Kagurazaka: stone-paved lanes and a quieter, older-Tokyo feel.
• Nishi-Shinjuku: office towers and the Tokyo Metropolitan Government Building, whose free observation deck is worth a visit.
• Yotsuya and Shinjuku Gyoen area: green space and calmer residential streets.

If you are still deciding between areas, this comparison of Shibuya vs Shinjuku explains how the two wards differ on rent, commute and daily life.

Keep your lease papers somewhere safe

You will need your contract for the renewal (usually every two years), for any repair requests, and for moving out. Note the notice period for leaving, typically one to two months, and the management company's contact number.
