Are you a VTuber or game streamer in Japan looking for a soundproof rental where you can stream without disturbing neighbors? Here’s the catch: not all soundproof rentals are suitable for streaming. Rentals designed for music performance differ significantly from optimal VTuber and game streaming environments.
This guide thoroughly explains the three essential elements VTubers and game streamers must consider when choosing soundproof rentals in Japan: internet speed, power capacity, and soundproofing performance. Plus, a comprehensive checklist to avoid costly mistakes.
3 Reasons VTubers & Game Streamers Choose Soundproof Rentals#
Reason ①: Stream Anytime Without Neighbor Concerns#
For VTubers and game streamers, streaming schedules often align with viewer availability—late nights and early mornings are common. In regular Japanese rentals, loud voices at night require neighbor consideration, limiting streaming content.
Soundproof rentals allow streaming without time restrictions.
Benefits for VTubers & Game Streamers:
- Late night/early morning streaming doesn’t disturb neighbors (D-45+ properties)
- Game streaming reactions and shouts unrestricted
- Horror game screams and FPS excitement uninhibited
- VTuber character voices (high/low pitches) performed freely
- ASMR silence requirements met
Especially for VTubers, character performances often require loud or distinctive voices. Soundproof environments let you focus on acting and maximizing character appeal.
Reason ②: High-Quality Streaming Without External Noise#
For VTubers and game streamers, audio quality significantly impacts viewer satisfaction. Even with entertaining content or skilled gameplay, poor audio drives viewers away.
Regular Japanese rentals inevitably let external noise contaminate streams, preventing professional streaming environments.
External Noise Blocked by Soundproof Rentals (D-50+)
- Vehicle traffic, motorcycle engines (-30~35dB)
- Neighbor sounds (TV, conversation, footsteps) (-25~30dB)
- Emergency vehicle sirens (-35~40dB)
- Rain, wind sounds (-20~25dB)
- Construction noise (-30~35dB)
Properties with D-50+ soundproofing substantially reduce this noise. Especially for ASMR streams, singing streams, and talk streams, this silence enhances viewer immersion.
Audio Quality Importance in Game Streaming:
- Voice chat (VC) audio clarity
- Accurate game sound effects delivery to viewers
- No external noise breaking viewer concentration
Reason ③: Acoustic Environment That Enhances VTuber & Streamer Voices#
Many soundproof rentals feature acoustic tuning for music performance. This benefits VTuber and game streaming too.
Benefits of Well-Tuned Soundproof Rentals:
- VTuber character voices recorded clearly and distinctly
- Game commentary easily reaches viewers
- Moderate reverberation without unpleasant echo
- Less microphone noise, easier audio editing
Important Note: Music-Focused ≠ Streaming-Focused
Soundproof rentals designed for music often have increased reverberation to beautify instrument tones. This can cause “excessive voice echo” problems for game streaming and talk streaming.
Additional Optimization for Streaming:
- Add acoustic foam (install on wall behind microphone)
- Introduce reflection filters
- Optimize desk placement (30cm+ from walls)
We’ll detail this in “Interior Acoustic Adjustment Techniques” later.
Required Soundproofing for VTubers & Game Streamers: D-Value Guidelines#
D-Values Different from Music: What VTubers & Game Streamers Need#
When selecting soundproof rentals in Japan, always check the “D-value” sound insulation indicator. Higher D-values mean better sound insulation, preventing sound leakage and external noise intrusion.
Music performance (drums, guitar amps, etc.) typically requires minimum D-50+, but VTubers and game streamers often find D-45 sufficient.
Recommended D-Values for VTubers & Game Streamers
| Stream Genre | Recommended D-Value | Reason | Rent Premium (Estimate) |
|---|---|---|---|
| Talk/Chat Streaming | D-40~45 | Conversation volume relatively low | +¥10,000 |
| Game Streaming (General) | D-45~50 | Reactions and shouts involved | +¥20,000 |
| Horror/FPS Streaming | D-50~55 | Screams and excited voices loud | +¥30,000 |
| VTuber Singing Streams | D-50~55 | Singing voice penetrates easily | +¥30,000 |
| ASMR Streaming | D-55~60 | External noise blocking critical | +¥40,000 |
| Instrument Performance | D-55~65 | Depends on instrument (piano, guitar, etc.) | +¥40,000 |
Higher D-values mean better soundproofing but correspondingly higher rent. Choose appropriate performance matching your streaming style and budget.
Important: D-Value Alone Insufficient
- D-value indicates “sound insulation between adjacent rooms”
- External noise (roads, trains) requires separate verification
- Floor vibration performance (L-value) also important (gaming chair vibration countermeasures)
Critical for VTubers & Game Streamers: Internet Selection Points#
Required Internet Speed for VTubers & Game Streamers in Japan#
For VTubers and game streamers, internet connectivity is the most critical infrastructure. No matter how perfect the soundproofing, slow internet causing stream stuttering will drive viewers away.
Why Internet Environment Should Be Top Priority in Soundproof Rental Selection:
- Difficult to improve later (limited by building infrastructure)
- Directly impacts stream quality
- Biggest factor affecting viewer satisfaction
Recommended Speeds by Platform (Upload)
| Platform | Quality | Required Upload | Recommended Upload | Stream Style |
|---|---|---|---|---|
| YouTube Live | 720p | 3 Mbps | 5~10 Mbps | Talk, chat streaming |
| YouTube Live | 1080p | 6 Mbps | 10~20 Mbps | Standard VTuber streaming |
| YouTube Live | 1080p 60fps | 10 Mbps | 20~30 Mbps | Standard game streaming |
| Twitch | 720p | 3 Mbps | 5~8 Mbps | Casual streaming |
| Twitch | 1080p 60fps | 8 Mbps | 15~25 Mbps | Game streaming |
| TwitCasting | Standard | 1 Mbps | 3~5 Mbps | Talk streaming |
| Discord Screen Share | 720p | 3 Mbps | 5~10 Mbps | Limited streaming |
Important Notes for Game Streamers
Above speeds are for “streaming only.” Game streaming requires additional bandwidth:
- Online game play: 10
30 Mbps download, 510 Mbps upload - VC tools (Discord, etc.): 1~3 Mbps upload
- Streaming software (OBS, etc.): 10~30 Mbps upload
Total 30+ Mbps upload minimum, ideally 50+ Mbps is optimal.
VTubers & Game Streamers Need Fiber! Property Viewing Verification#
When selecting soundproof rentals, verify internet environment during property viewing. Discovering “internet too slow for streaming” after signing is too late.
Internet Points VTubers & Game Streamers Must Verify During Viewing
Connection Type Verification
- Fiber optic (fiber to each room): ★★★★★ Top priority
- LAN wiring (fiber to building, LAN to room): ★★★★☆ Acceptable
- VDSL (via telephone lines): ★☆☆☆☆ Avoid
ISP Verification
- Flets Hikari (max 1 Gbps): Nationwide, high stability
- NURO Hikari (max 2 Gbps): Strong upload speed, streaming-optimized
- au Hikari (max 1 Gbps): Independent network, congestion-resistant
- SoftBank Hikari (max 1 Gbps): IPv6 support, high-speed
Building Sharing Status
- Independent connection per room: ★★★★★ Most stable
- Building-wide shared: ★★☆☆☆ Possible evening speed reduction
Construction Feasibility & Costs
- Is fiber optic construction possible?
- Who bears construction costs? (landlord or self)
- Construction timeline (immediate move-in possible?)
Absolutely Avoid: VDSL Soundproof Rentals
Common in older soundproof rentals, VDSL (via telephone lines) has 100 Mbps download maximum, with actual speeds 20~50 Mbps. Upload speeds are even slower—unsuitable for streaming.
For streaming-focused living, prioritize fiber optic (fiber to each room) properties.
VTuber & Game Streamer Power Supply: Preventing Mid-Stream Breaker Trips#
Calculate VTuber & Game Streaming Equipment Power Consumption#
VTuber and game streaming environments consume surprisingly high power. Mid-stream breaker trips ruin all streaming progress.
VTuber & Game Streaming Equipment Power Consumption Examples
| Equipment | Power Consumption | Notes |
|---|---|---|
| Gaming PC | 300~500W | High load with graphics card |
| Monitors (2~3) | 100~200W | Dual/triple displays |
| Audio Interface | 10~30W | Increases with phantom power |
| Lighting (Ring lights, etc.) | 50~100W | Essential for VTuber streaming |
| Air Conditioning | 500~1,000W | Essential in sealed soundproof rooms |
| Chargers, Smartphones | 50~100W | Notification checking during streams |
| Gaming Chair Massage Function | 30~50W | If used |
| Total | ≈1,040~1,980W |
Important: Japanese Household Outlet Limitations
- Single circuit (breaker) typically 1,500W maximum
- Exceeding this trips breaker, interrupting stream
- Soundproof room outlets often on single circuit
Preventing Mid-Stream Breaker Trips:
- Verify property power capacity beforehand (ask management during viewing)
- Put air conditioning on separate circuit (when possible)
- Choose LED lighting (lower power consumption)
- Install UPS (uninterruptible power supply) for power interruption protection
VTubers & Game Streamers Must Verify Outlet Count During Viewing#
During property viewing, definitely verify outlet count and positions. For VTubers and game streamers with extensive equipment, outlet shortage is critical.
Required Outlet Count for VTuber & Game Streaming Rooms
| Equipment | Required Outlets |
|---|---|
| PC + Monitors (2~3) | 3~4 outlets |
| Audio interface + Lighting | 2 outlets |
| Chargers, Smartphone | 1~2 outlets |
| Air Conditioning | 1 outlet (dedicated circuit) |
| Total | 7~9 outlets |
- Minimum 6+ outlets (4 outlets definitely insufficient)
- Ideal 8~10 outlets (considering equipment expansion)
- Multiple wall locations ease wiring (concentrated desk-side placement ideal)
Soundproof Rental Outlet Situations
Some soundproof rentals have extra outlets installed for music equipment. Conversely, older properties may have only 2 outlets—beware.
Viewing Verification Method:
- Count soundproof room interior outlets
- Photograph placement for records
- Verify which walls have outlets (reference for desk placement)
- Ask management “Can outlets be added for streaming equipment?”
Insufficient Outlet Solutions:
- Use power strips (avoid daisy chaining, use parallel connections)
- Use wall-mounted extension cords (reduce floor wiring)
- Request addition construction with landlord permission (¥20,000
50,000 / $130330, negotiable) - Consolidate USB-powered devices via USB hub (supplied from PC power)
