Furniture tipping accidents during earthquakes cause many deaths and injuries. Estimates for a major earthquake directly under the capital suggest that roughly 30–50% of indoor injuries would result from furniture and appliance tipping and falling. However, in rental apartments, earthquake preparations often take a backseat due to concerns—"Are we allowed to drill holes in walls?" and "Will we be charged for repairs at move-out?"
This article compares the main furniture-securing methods across three dimensions—cost, prevention effectiveness, and restoration risk—and identifies approaches practical for renters. For a complete earthquake-preparedness guide (evacuation planning, full product lists, etc.), see our separate article "The Complete Earthquake-Preparedness Guide for Rental Apartments."
A type that secures by extending between the ceiling and the top of the furniture. Representative products include Diawalls and dedicated anti-tipping devices.
| Item | Details |
|---|---|
| Price range | ¥1,000–¥5,000 per unit |
| Securing effect | Medium to high (depends on ceiling strength) |
| Restoration risk | Low (ceiling marks may remain in some cases) |
| Installation difficulty | Easy (no tools required) |
Note: Drywall ceilings are weak under load, and tension rod components may leave indentations. Using dedicated pads or backing plates minimizes marks.
A method that secures L-brackets to wall studs or backing with screws, directly connecting the furniture to the wall.
| Item | Details |
|---|---|
| Price range | ¥200–¥500 per bracket (plus installation) |
| Securing effect | Very high (most reliable) |
| Restoration risk | High (screw holes remain in wall) |
| Installation difficulty | Medium to difficult (stud location confirmation required) |
For rental apartments: Move-out repair costs for screw holes are likely. Obtain written permission from the property manager before installation. If installed with permission, restoration obligations may be reduced in some cases (see Ministry of Land, Infrastructure, Transport and Tourism guidelines).
Estimated costs (including move-out repairs):
Gel or sticky-sheet types that adhere to furniture legs or backs.
| Item | Details |
|---|---|
| Price range | ¥500–¥3,000 per set |
| Securing effect | Low to medium (weak against horizontal shaking) |
| Restoration risk | Very low (fine marks may remain on flooring) |
| Installation difficulty | Extremely easy (just stick and go) |
Note: Insufficient for preventing large furniture (bookshelves, china cabinets, etc.) from tipping. Best suited as supplementary protection for side tables and small shelves.
Devices placed under furniture legs that absorb and distribute seismic energy.
| Item | Details |
|---|---|
| Price range | ¥2,000–¥10,000 per set (4-piece) |
| Securing effect | Medium (reduces front-to-back and side-to-side sliding; does not prevent tipping) |
| Restoration risk | Nearly zero (simply placed on flooring) |
| Installation difficulty | Extremely easy |
Note: More effective at preventing furniture from sliding and damaging walls than at preventing tipping. Best suited for small heavy items like TVs and AV equipment.
A type that uses a belt to secure from the top of the furniture to a wall stud.
| Item | Details |
|---|---|
| Price range | ¥1,500–¥4,000 per unit |
| Securing effect | High (assumes anchoring to a stud) |
| Restoration risk | Medium (screw holes may remain at attachment points) |
| Installation difficulty | Medium (stud location confirmation required) |
| Furniture Type | Recommended Method | Reason |
|---|---|---|
| Large bookshelves, china cabinets | Tension rods or wall securing (after obtaining permission) | Heavy and dangerous if they tip |
| Refrigerator | Dedicated anti-tipping straps + seismic isolators | Prevents secondary damage to electrical and gas systems |
| TV | Dedicated anti-tipping belts + isolation pads | Prevents power cord strain |
| Washing machine | Anti-vibration rubber mats | Reduces vibration and prevents movement |
| Chest of drawers, storage boxes | Tension rods or adhesive sheets | May also serve as room dividers |
| Method | Estimated Total Cost | Effectiveness Level | Restoration Risk |
|---|---|---|---|
| Adhesive sheets | ¥500–¥3,000 | Low | Very low |
| Seismic isolators | ¥2,000–¥10,000 | Medium | None |
| Tension rods (with backing plates) | ¥3,000–¥12,000 | Medium to high | Low |
| Belt-type wall securing | ¥2,000–¥8,000 | High | Medium |
| L-bracket wall securing | ¥3,000–¥20,000 (including move-out repairs) | Very high | High |
For renters looking to minimize costs, the combination of tension rods (with backing plates) + seismic isolators is the most practical option, offering reasonable protection while minimizing restoration risk.
For earthquake-proofing furniture in rentals, tension rods (using ceiling backing plates) offer the best balance of cost, effectiveness, and restoration risk, costing approximately ¥1,500–¥3,000 per piece. Wall screwing is most effective but carries restoration risk; always obtain written permission from the property manager before proceeding. For L-brackets and belt securing, it's important to estimate move-out repair costs beforehand and make decisions based on cost-effectiveness.
