While "free internet" properties sound attractive, they involve landlord installation costs and quality limitations. This article provides practical guidance for foreign tenants—who often face difficulties setting up their own internet contracts after arriving in Japan—to understand the real benefits and potential drawbacks.

In recent years, rental properties in Japan that advertise "free internet" and "Wi-Fi equipped" have increased rapidly. On major property portals like SUUMO, LIFULL HOME'S, and Atohom, 30–40% of new and newly built apartments and 20–30% of single-person apartments now bear the "free internet" label. This trend reflects both landlords' differentiation strategies and changing tenant preferences.

There are two types of guarantees for rental leases: joint guarantors and guarantor companies. We'll explain in detail how each works, their advantages and disadvantages, and how to choose the right option.
According to the Ministry of Land, Infrastructure, Transport and Tourism's housing market survey, the proportion of tenants citing "internet environment" as an important factor in choosing a rental property jumped from 42% in 2015 to 78% in 2025. In particular, with the spread of remote work and online classes, having high-speed internet available on move-in day has become a deciding factor in property selection.
For foreign tenants, free internet properties offer value beyond just cost savings. Shortly after arriving in Japan, setting up internet through major providers like NTT, au Hikari, or SoftBank Hikari involves multiple hurdles: presenting a residence card, dealing with Japanese-language requirements, scheduling installation work, and paying initial setup fees of ¥20,000–¥40,000. With free internet properties, tenants can begin using the internet on day one without any contract procedures, significantly shortening the onboarding period after arrival in Japan.
Understanding how landlords structure their internet costs will help you make better choices when selecting a property.
Landlords generally choose from three main approaches. First, bringing fiber-optic cable to the building common areas only and distributing it to each unit via VDSL (copper telephone lines). Installation cost per building: ¥500,000–¥1.5 million. Monthly management fee: ¥50,000–¥150,000 per building. Typical download speed per unit: 20–80 Mbps—sufficient for video streaming and remote work, but may experience lag with 4K streaming or online gaming.
Second, Fiber-to-the-Home (FTTH), which runs fiber-optic cable directly to each unit. Installation cost per building: ¥1.5–¥4 million. Monthly fee: ¥30,000–¥80,000. Typical download speed: 200–900 Mbps—comfortable for families and those working from home full-time. Commonly found in newer and luxury apartment buildings.
Third, home router or pocket Wi-Fi devices. Landlords contract these at ¥2,500–¥4,500 per month per unit and provide them to tenants. Installation cost is nearly zero, but typical download speed is only 10–50 Mbps and can become extremely slow during evening peak hours.
Listing pages on SUUMO or HOME'S usually only say "free internet," so you need to ask about the actual system and speeds during a property viewing.
When viewing a free internet property, be sure to ask your real estate agent these four questions:
First: Internet type (FTTH, VDSL, or home router). Many real estate agents can't answer this on the spot. Ask them to contact the property management company right away, or get the direct phone number for the management company or provider so you can call yourself.
Second: Actual download speeds. For new buildings, you may only find theoretical maximum speeds, but for occupied buildings a year or older, you might get speeds closer to what current tenants experience. If possible, test the connection in the unit using fast.com or speedtest.net on your smartphone during the viewing—it only takes a minute if they give you the Wi-Fi password.
Third: Speed during evening peak hours. In shared-connection buildings, speeds can drop to one-tenth or less between 7 pm and 11 pm when all residents are online. Always ask about evening speeds.
Fourth: Support and response time for problems. If the internet goes down, do you contact the provider directly or go through the management company? Is multilingual support available? What's the average repair time? Get these answers in writing before signing the lease.
You don't have to rely on free internet—contracting your own fiber-optic service is becoming easier for foreign residents. Here are realistic options:
First option: Budget mobile SIM services (Rakuten Mobile, LINEMO, ahamo, etc.). You can get 20–100 GB per month for ¥3,000–¥4,000, and use phone tethering as home Wi-Fi. You need only a residence card and can find English-speaking shops.
Second option: Home routers (SoftBank Air, WiMAX, Rakuten Turbo, etc.). No installation needed—just plug in. ¥4,000–¥5,500 per month for 50–200 Mbps. You need a residence card and credit card.
Third option: NTT fiber (Flets Hikari or collaboration services) + provider contract. ¥4,500–¥6,000 per month for 300–900 Mbps. Installation takes 2–4 weeks and English support is limited, but this is ideal for families and long-term residents.
Ask your real estate agent for referrals to "foreign-resident friendly" fiber providers—this makes the process smoother. Some multilingual guarantor companies like GTN and Casa have partner providers.
Here's what works best depending on your situation:
International students (1–2 year stay, ¥40,000–¥60,000 rent, online classes in your room): Prioritize free internet properties. Even 20–80 Mbps (VDSL) is plenty for Zoom and YouTube. Setting up your own fiber costs ¥80,000–¥100,000 in the first year, so choosing a free property saves that while supplementing with phone tethering when needed is the most cost-effective approach.
Work visa holders (single) (3–5 year stay, ¥60,000–¥90,000 rent, remote work 2–3 days per week): Prioritize FTTH free internet properties. VDSL or home router speeds risk being too slow for work, so it's safer to assume you'll need your own NTT fiber and choose accordingly. If your employer covers internet costs, your out-of-pocket is nearly zero.
Families (4+ members, ¥100,000+ rent, simultaneous online learning, streaming, and remote work): Even if a property offers free internet, I recommend getting your own FTTH fiber. Families need speed that can handle multiple simultaneous users, and ¥5,000/month is worth the investment.
Free internet properties significantly ease the transition for foreign residents right after arrival. By confirming the connection type, checking evening speeds, and assessing whether it fits your usage patterns, you can maximize the benefit while remaining flexible to upgrade to your own contract if needed.
