Navigating a Tenant’s Request to Keep a Musical Instrument

About twice a year, one of my tenants asks if they can bring in a musical instrument. Last spring it was an electric keyboard, the year before that a full drum kit for a college student’s kid. Out of the 9 units I manage myself, I’ve said yes 4 times and no twice, and the difference usually comes down to 3 things: the instrument, the building, and whether the tenant is willing to invest in noise control themselves.

If you own rental property in Japan long enough, this request will land in your inbox. Handling it well protects your other tenants, your walls, and your renewal rate all at once.

Why This Comes Up More Than You’d Expect

Japan has one of the highest per-capita piano ownership rates in the world, and with home practice for guitar, violin, and electronic drums growing since 2020, I’d guess at least 15% of tenants under 40 either already own an instrument or are thinking about picking one up. Most leases here are silent on the topic entirely, which means tenants often assume it’s fine until a neighbor complains. I’d rather deal with the question upfront than the complaint six months later. I’ve also noticed the requests cluster right around move-in season, roughly February through April, when new tenants are still unpacking and haven’t yet learned the building’s habits, so I now bring the topic up myself during the move-in walkthrough instead of waiting to be asked.

Check What Your Lease Actually Says About Noise

Standard Japanese rental agreements almost always include a general noise clause, something like a ban on causing disturbance to neighboring residents, but very few spell out instruments specifically. When I revised my own lease template about 4 years ago, I added a line requiring written landlord approval before bringing in any instrument capable of producing sustained sound above normal conversation level. That single clause has saved me from at least 3 disputes where a tenant claimed they never knew it was an issue. If your current lease says nothing, don’t assume silence protects you u2014 assume it protects the tenant.

Not All Instruments Carry the Same Risk

I sort requests into three rough tiers before I even think about soundproofing:

• Low risk u2014 headphone-compatible electronic keyboards, electric guitars played through headphones, ukulele, most string instruments played quietly
• Medium risk u2014 acoustic guitar, violin, brass or wind instruments practiced for under an hour a day
• High risk u2014 acoustic piano, drum kits (acoustic or electronic with a physical kick pedal), any amplified instrument played through speakers

An acoustic upright piano can register 85 to 95 decibels at the source, which is loud enough to carry through a standard 12cm reinforced concrete wall if there are any gaps around plumbing or window frames. Drums are worse because the impact travels through the floor structure, not just the air, so a downstairs neighbor feels it as much as hears it.

Soundproofing Options I’ve Actually Tested

For medium-risk instruments, I’ve had good results asking the tenant to install a floor mat rated for sound insulation, which typically runs about 8,000 to 15,000 yen for a 2-mat set covering a 6-tatami room, plus a portable isolation shield behind an amp if they play electric guitar. For anything higher risk, I require one of two things before approval: a dedicated soundproof room addition, which I’ve quoted at 250,000 to 400,000 yen depending on wall thickness and floor isolation, or a hard restriction to electronic instruments with headphone output only. In one of my properties built in 2009 with better insulation specs, I allowed an acoustic piano with a rule limiting practice to between 10am and 7pm and capping sessions at 90 minutes. It’s worked for over 3 years with zero complaints, but I wouldn’t try that in my older 1998-built building down the street u2014 the walls just aren’t thick enough.

Put the Rules in Writing Before You Say Yes

Every time I’ve approved an instrument, I’ve done it through a short written addendum to the lease, not a verbal okay. It covers permitted hours, maximum volume expectations, what happens if a neighbor files a complaint (usually a 2-warning system before the approval is revoked), and confirmation that the tenant will cover any soundproofing costs themselves. This isn’t about being difficult u2014 it’s about having something concrete to point to if a dispute ever escalates to your rental management company or, in rare cases, small claims. I keep a copy in both the tenant’s file and my own records, and I ask them to sign within 5 business days of the request. I also note the addendum in my annual lease review, since about 1 in 5 of my tenants renews every year, and I’d rather catch an expired or forgotten agreement at renewal time than after a new neighbor moves in and starts complaining.

When I Say No

I’ve turned down two requests outright: an acoustic drum kit in a wood-frame building with paper-thin floors, and a tenant who wanted to practice trombone daily in a unit directly above an elderly resident who complained about far quieter things. In both cases I offered an alternative u2014 a nearby rental practice studio, which in most Japanese cities runs somewhere around 500 to 1,000 yen per hour u2014 rather than a flat refusal with no path forward. Tenants respond much better to a no that comes with an option than a no that just shuts the door. I’ve had one tenant take that studio suggestion, keep the lease for another 2 years, and never bring the instrument up again u2014 proof that a workable alternative usually matters more to people than getting the exact answer they originally wanted.

That’s the balance I try to strike across all 9 of my properties: protect the building and the neighbors, but don’t make music one more thing your tenants have to hide from you.
