Moving to Toyosu: The Ultimate Foreigner’s Guide to Renting in Koto-ku (2026)

Welcome to your complete guide to renting an apartment in Toyosu, Tokyo. Whether you are relocating to Japan for the first time or moving within Tokyo, finding the right home can be a daunting process.

This guide is written and reviewed by a licensed takken-shi (宅地建物取引士) who lives in Koto-ku. Marokama is not a brokerage and does not list property. This guide will walk you through the rent market, hidden costs, and how to pass the strict screening processes in this highly sought-after waterfront district.

Not ready for a two-year lease? If you need a short-stay place for one to six months while you settle in, a serviced or by-the-month unit is usually cheaper and far simpler — no key money, no guarantor. Full prices, contract terms and booking steps are in our guide to monthly, furnished & serviced apartments in Toyosu.

Why Toyosu is the Top Choice for Expats in Tokyo

Toyosu has transformed from an industrial port into Tokyo’s premier family-friendly waterfront district. For expats and young professionals, it offers a lifestyle that is rare in central Tokyo: wide sidewalks, massive parks, and high-end apartments with stunning views of Tokyo Bay.

Plus, with direct access to the Yurakucho Line and Yurikamome, you can reach Ginza in just 7 minutes and major business hubs like Otemachi in under 15 minutes.

2026 Rent Market Trends in Toyosu

Because over 80% of residential properties in Toyosu are luxury high-rise “Tower Mansions” built after 2005, the rent here is higher than the Koto-ku average. These buildings often feature 24/7 concierge services, fitness centers, and sky lounges.

Here is a quick look at the average monthly rent in Toyosu:

Layout Type	Approx. Size	Average Rent (Monthly)	Best Suited For
Studio / 1K	25 – 35 sqm	¥120,000 – ¥160,000	Singles, Young Professionals
1LDK (1 Bed)	40 – 55 sqm	¥180,000 – ¥270,000	Couples, Single Executives
2LDK / 3LDK	60 – 85 sqm	¥300,000 – ¥550,000+	Families with children

Essential Japanese Rental Customs & “Hidden” Costs

Before signing a contract, you must understand Japan’s unique initial costs. In Toyosu, the upfront move-in cost is typically 4 to 6 times the monthly rent.

Deposit (Shikikin / 敷金): Usually 1-2 months’ rent. This is held by the landlord for damages and cleaning fees when you move out.
Key Money (Reikin / 礼金): Usually 1 month’s rent. This is a non-refundable “gift” to the landlord. (Note: As a Takken Shi, I can sometimes negotiate this down for you!)
Broker Fee (Chukai Tesuryo / 仲介手数料): Capped by Japanese law at 1.1 months’ rent (including tax).
Guarantor Company Fee (Hoshogaisha / 保証会社): Usually 50% to 100% of one month’s rent. Most landlords in Toyosu require this even if you have a high income.

3 Tips to Pass the Rental Screening as a Foreigner

High-end apartments in Toyosu often have stricter financial requirements set by major developers (like Mitsui or Mitsubishi). Here is how to prepare:

Prepare Income Documentation: You will need an employment contract or tax certificate showing an annual salary of at least 3 times the yearly rent.
Secure a Japanese Emergency Contact: Even with a guarantor company, almost all management companies require a Japanese-speaking emergency contact residing in Japan.
Leverage Corporate Contracts: If your employer is willing to sign the lease on your behalf (Corporate Contract / Hojin Keiyaku), your chances of passing the screening in luxury towers increase significantly.

The Honest Pros and Cons of Living in Toyosu

To help you make an informed decision, here is an honest, unbiased look at daily life in Toyosu:

Healthcare Access: Proximity to major hospitals like Showa University Koto Toyosu Hospital.
Green Spaces: Excellent parks like Toyosu Park, perfect for jogging and weekend picnics.

The Cons:

Ready to Read the Fine Print? Ask a Takken-shi

Searching through Japanese real estate portals can be frustrating due to outdated listings and hidden language barriers.

A takken-shi cannot give you access to the industry database (REINS) — that is restricted to licensed brokerages, and Marokama is not one. Nor can Marokama negotiate for you or act as your agent. What a takken-shi can do is read a listing, and the disclosure documents behind it, and tell you in English what they actually say — including what they leave out.
