Internet-Free Rentals vs. Self-Contracted Plans: Which Costs Less? — Comprehensive Comparison of Speed, Fees, and Contract Flexibility

The Truth About "Internet-Free" Properties

Rental properties advertised as "internet-free" are popular on apartment search sites. However, choosing without understanding what "free" actually means can lead to disappointment—experiencing slow speeds that make the service unusable, or ending up subscribing to a separate mobile Wi-Fi plan. In this article, we compare internet-free properties with self-contracted plans across five key dimensions, drawing on 2026 market rates, and provide tailored recommendations for different use cases.

Three Types of "Internet-Free" Properties

Type 1: Shared Building-Wide Internet

A single optical fiber line serves the entire building, shared by all units. LAN wiring extends to each apartment. The cost is typically included in the maintenance fee.

Features

• •No installation work required; internet available immediately upon move-in
• •No monthly fee (included in rent and maintenance fee)
• •Speed decreases during evening peak hours due to shared usage
• •Router setup and configuration are your responsibility

Speed Reality

Speeds often drop to 10–30 Mbps during peak evening hours (9–11 PM). Zoom calls and standard video streaming work fine, but simultaneous 4K streaming and large file uploads become challenging.

Type 2: Individual VDSL Lines

This system uses individual telephone lines in each unit. Common in buildings over 20 years old, with a speed ceiling of 100 Mbps (typically around 50 Mbps in practice). There is also a risk of aging infrastructure.

Type 3: Provider-Partnership "Free" Plans

The property owner contracts with a specific provider and includes the cost in the rent. You cannot choose your provider, and speed and quality depend entirely on that provider's service.

Self-Contracted Fiber-Optic Plans

Major Fiber-Optic Services (as of 2026)

Installation fees are often effectively waived through promotional campaigns that spread the cost over 36 monthly payments.

Advantages and Disadvantages of Self-Contracted Plans

Advantages

• •Freedom to choose your provider
• •Higher speed ceilings (1–10 Gbps)
• •IPv6 IPoE-compatible providers can bypass evening congestion
• •Service can continue when you move

Disadvantages

• •Installation can take 1–2 months
• •Installation and setup fees apply
• •Early termination fees apply to 2-year contracts
• •Internet is not available immediately upon move-in

Monthly Cost Comparison

Compare a ¥80,000 rent with included internet against ¥78,000 rent plus a self-contracted ¥4,000/month fiber plan. The net monthly cost is ¥80,000 vs. ¥82,000—a ¥24,000 annual difference. Generally, internet-inclusive properties are priced ¥2,000–4,000 higher.

During evening peak hours, while internet-free properties drop to 10–50 Mbps, self-contracted IPv6 IPoE plans maintain 100–500 Mbps. For remote work or online gaming, self-contracted service is preferable.

Use Case–Specific Solutions

Remote Work Focus (Zoom Calls, Document Creation) → Self-Contracted

Zoom calls require stable speeds. To avoid quality degradation during evening peak hours, self-contracted fiber service is recommended.

Video Streaming Focus (Netflix, YouTube) → Internet-Inclusive Property

Even 4K streaming requires only around 25 Mbps. Most free internet services can provide this speed.

Online Gaming Focus → Self-Contracted (IPv6 IPoE)

Ping latency matters more than speed. For FPS and MMO games requiring sub-10ms ping, self-contracted service is essential.

Short-Term Stay or Business Trip (6 Months or Less) → Internet-Inclusive Property or Mobile Wi-Fi

Self-contracted service is not cost-effective when you factor in installation time and early termination fees. Comparing with mobile Wi-Fi rental (¥3,000–5,000/month) is worthwhile.

International Students and Foreign Residents → Internet-Inclusive Property

Contracting for fiber service in Japanese can be challenging. Internet-inclusive properties are available immediately upon move-in.

Things to Verify Before Viewing and Signing a Lease

When viewing a property, confirm the following:

• •Connection type (shared fiber, VDSL, or wireless)
• •Provider name and advertised maximum speed
• •Location of LAN ports in the unit (living room or bedroom)
• •Whether Wi-Fi router installation is permitted
• •Procedures for cancellation upon move-out

Using fast.com or speedtest.net on your smartphone during the viewing is an effective way to test actual speeds. It's also important to ask the real estate agent about actual nighttime speeds beforehand.

Summary

Whether an internet-inclusive property or self-contracted service makes sense depends on your use case. Self-contracted plans are advantageous for remote work and gaming, while internet-inclusive properties often work better for streaming, short-term stays, and foreign residents. Test speeds during viewings and match your decision to your actual internet usage patterns to avoid regret.

When choosing a property, consider both speed and monthly cost, and make your decision based on your actual internet usage style.
