Finding an apartment in Japan is one of the first real tests of life as a foreign developer here. The system is different from most countries — there's upfront money you didn't expect, paperwork in Japanese, and landlords who may quietly decline foreign applicants. But once you understand the rules, it's very manageable. This guide covers everything from picking the right neighborhood to signing the contract.

Understanding Japanese Apartment Types

Japanese apartments are categorized by a number + letter system. The number is the count of separate rooms (bedrooms), and the letter indicates what else is included: K (kitchen), DK (dining + kitchen), or LDK (living + dining + kitchen). Here's what each type looks like in practice:

1K
18–28 m²

One room with a small separate kitchen. Cheapest option. Fine for minimalists, but tight if you work from home.

1DK
25–35 m²

One bedroom + a dining/kitchen combo. A noticeable step up from 1K. Better for cooking and eating properly.

1LDK
35–50 m²

One bedroom + a proper living/dining/kitchen area. The sweet spot for developers who work from home.

2LDK
50–70 m²

Two bedrooms + LDK. Ideal if you want a dedicated home office, or you're moving with a partner.

Developer tip

If you work remotely or do side projects at home, don't cheap out on a 1K. The jump from 1K to 1LDK is usually only ¥10,000–20,000 more per month, but the quality-of-life difference is enormous. A proper desk setup in a separate room does wonders for your focus and your video calls.

Setting Your Budget

A common rule of thumb in Japan is to keep rent within 25–30% of your monthly take-home pay. On a ¥5,000,000 annual salary (~¥330,000/month take-home after tax), that means a rent budget of roughly ¥80,000–100,000. Not sure what your take-home looks like? See our IT Salary Guide for a full breakdown by level.

Here's a realistic rent range by city for a 1LDK apartment in a decent location:

City 1K 1LDK 2LDK
Tokyo (central) ¥80,000–120,000 ¥120,000–180,000 ¥160,000–250,000
Tokyo (suburban) ¥55,000–80,000 ¥80,000–120,000 ¥100,000–150,000
Osaka ¥45,000–70,000 ¥65,000–100,000 ¥85,000–130,000
Nagoya ¥40,000–65,000 ¥60,000–90,000 ¥80,000–120,000
Fukuoka ¥35,000–55,000 ¥55,000–80,000 ¥70,000–100,000
Remote worker advantage: If your company allows full remote, consider basing yourself in Osaka or Fukuoka. You'll pay roughly half Tokyo's rent, commute to the office a few times per month, and keep a significantly larger chunk of your salary.

The Upfront Costs (What Nobody Tells You)

This is where Japan's rental system catches most people off guard. Moving into a Japanese apartment isn't just first month's rent — it's a stack of fees paid all at once before you get the keys.

Fee Japanese Term Amount Notes
Security deposit 敷金 (shikikin) 1–2 months' rent Returned at move-out, minus any damage charges
Key money 礼金 (reikin) 0–2 months' rent A "gift" to the landlord. Non-refundable. Many newer apartments no longer require this.
Agency fee 仲介手数料 0.5–1 month's rent Paid to the real estate agency. Legally capped at 1 month.
Guarantor company fee 保証会社費用 0.5–1 month's rent Required for most apartments. Replaces the traditional personal guarantor.
First month's rent 前家賃 1 month Sometimes pro-rated if you move in mid-month
Lock replacement 鍵交換費用 ¥15,000–30,000 Standard safety fee. Usually required.
Fire insurance 火災保険 ¥15,000–25,000/year Mandatory. Can shop around — don't just accept the agency's option.
Typical total (on ¥80,000/month rent) ¥280,000–480,000
Watch out

Reikin (key money) is the big one. Some landlords still require 1–2 months of non-refundable key money. When comparing apartments, always check whether reikin is listed as 0ヶ月 (zero months). Many modern buildings — especially newer constructions — have dropped it entirely. Searching with the filter "礼金なし" (no key money) can save you ¥100,000+.

Renting as a Foreign Developer

The honest truth: some landlords in Japan won't rent to foreigners. It's not universal — the situation has improved a lot in major cities — but it still happens. Here's how to navigate it:

What landlords look for

If a landlord declines you

Don't take it personally — move on. There are thousands of listings in any major city. Agencies that specialize in foreign tenants (see the Apps & Platforms section below) have pre-vetted landlords who are open to renting to internationals. They'll save you a lot of rejected applications.

"I got rejected twice in my first search in Tokyo. I switched to an agency that specializes in foreigners and found a great place within a week. The key is working with the right people, not fighting the wrong landlords."

Choosing the Right Neighborhood

For developers, the main factors are: commute time, internet quality, cafe culture (for working outside), and proximity to tech meetups. Here are strong options by city:

Tokyo

Osaka

Fukuoka

Developer tip

Before committing to a neighborhood, do a test commute during rush hour. Google Maps timing is accurate, but the experience of a packed Tokyo train at 8:30 AM is something you need to feel once before deciding. A 45-minute commute in Japan is comfortable on most lines — a 30-minute one on a busy Yamanote Line stop can be brutal.

Apps & Platforms to Search for Apartments

SUUMO
Best overall

Japan's most popular real estate portal. Widest selection. Interface is in Japanese but very learnable. Use filters like 礼金なし (no key money) and 外国人入居可 (foreigners welcome).

GaijinPot Apartments
Foreigner-friendly

English-language listings from foreigner-friendly landlords. Smaller selection than SUUMO but zero language barrier. Great starting point when you first arrive.

Sakura House
Short-term / Share

Share houses and monthly apartments across Tokyo and Osaka. No guarantor needed. A smart option for your first 1–3 months while you settle and find a long-term place.

Homes.co.jp
Wide selection

Second largest portal after SUUMO. Worth cross-referencing to catch listings that don't appear on SUUMO.

at-home
Agency direct

Strong for finding agency-direct listings. Some exclusive inventory you won't find on SUUMO. Good UI for filtering by features.

UR Chintai
No guarantor needed

Government-managed apartments. No key money, no guarantor company fee, no agency fee. Longer waitlists but excellent value. Worth checking if you're not in a rush.

The Apartment Search Process, Step by Step

Step 1 — Start searching 1–2 months before your target move-in date

Japanese apartments move fast. Good listings in popular neighborhoods get snapped up within days. Start browsing 6–8 weeks out, and be ready to make a decision within 24–48 hours of a viewing.

Step 2 — Use a real estate agency (fudousan)

You don't sign directly with landlords in Japan — you go through a real estate agency (不動産屋 / fudousan-ya). Find one near your target neighborhood, bring your zairyu card, and tell them your budget, preferred area, and move-in date. They'll pull listings and schedule viewings.

If your Japanese is limited, look for agencies with English-speaking staff. Able Agent, Fontaine, and ABLE (エイブル) have branches with English-capable staff in major cities.

Step 3 — Visit in person

Always view the apartment in person before agreeing. Check: natural light at your intended working hours, mobile signal strength (pull up a speed test in the room), noise from the street or neighboring units, distance to the nearest konbini, and actual room dimensions vs. the floor plan.

Developer tip

Run a Wi-Fi speed test in the apartment — or at least check mobile signal. Japan's internet is excellent once you're set up with fiber, but if you need to work remotely during the 1–2 weeks before your home fiber is installed, you'll be relying on your phone's hotspot. Weak signal in a concrete building is a real problem.

Step 4 — Apply and submit documents

Once you pick an apartment, you submit an application (申込書). Typical documents required:

Approval typically takes 2–5 business days. The guarantor company does their own background check — this is where applications from foreigners sometimes get slowed down.

Step 5 — Sign the contract (重要事項説明)

Before signing, the agency is legally required to walk you through a 重要事項説明 (juuyou jikou setsumei) — a detailed explanation of the contract terms. This is done in Japanese. Key things to confirm:

Important

Ask the agency to clarify the move-out restoration cost (原状回復 / genjou kaifuku) policy upfront. Japan's guidelines say normal wear and tear is the landlord's responsibility — but some contracts try to shift the cost to tenants. Know what you're signing before you pick up the keys.

Setting Up Your Apartment as a Developer

Getting fiber internet

This is your first priority. Most Japanese apartments support fiber — check whether the building has 光回線 (hikari kaisen) infrastructure. The main providers are:

Setup takes 2–4 weeks after application. In the meantime, get a pocket Wi-Fi or SIM card as a temporary solution. Rakuten Mobile's unlimited data at ¥3,278/month works well as a bridge.

Essential utilities to set up on day one

Furniture and appliances

Most Japanese apartments come completely empty — no appliances, no curtains, sometimes not even light fixtures. Budget for:

Developer tip

Check Junk Market (ジャンク市場), Hard Off, and the Facebook Marketplace equivalent Mercari for used appliances. You can furnish an entire apartment for ¥50,000–80,000 buying second-hand. Many departing expats also sell complete furniture sets at low prices — check r/japanlife and local foreigner Facebook groups.

Move-Out: Avoid Common Pitfalls

Move-out is where many foreigners get hit with unexpected charges. Here's how to protect your deposit:
