My first rental property came with a toolbox that held one flathead screwdriver, a rusty hammer, and a tape measure that no longer retracted. That was fine for hanging a calendar, but the night a tenant called about a running toilet at 9 pm, I realized I owned nothing that could actually fix it. Fifteen years and 9 rental units later, I’ve settled on a kit that handles roughly 80% of the repair calls I get without a single emergency trip to the hardware store.
If you’re just starting out as a landlord, you don’t need a garage full of equipment on day one. You need a focused set of tools that covers plumbing, light electrical work, drywall patching, and general fastening. Here’s what I’d buy first, based on the calls that actually come in.
Start With the Repairs You’ll Actually Face

18V Professional Impact Driver
My most-used tool. If you own one power tool, make it this.
In my first year of managing a single unit, about 60% of my maintenance calls fell into just three categories: a loose or leaking fixture, a door or cabinet hinge working itself out, and a small drywall hole from moving furniture. None of that requires specialty equipment. It requires a handful of reliable basics you can grab in under a minute, because a tenant with no working faucet at 8 pm does not care that you’re still deciding which drill to buy.

Power Tool Combo Kit (18V)
Combo kits are always better value than individual tools u2014 one battery charges all.
This is the kit I keep in a single carry case, and it has ridden along to more than 200 repair visits across my properties. Spend around 15,000 yen here and you’ll cover most jobs:
- 16 oz claw hammer for hanging, prying, and light demolition
- A 6-in-1 screwdriver with interchangeable Phillips and flathead bits
- Adjustable wrench, 25 cm, for fixture nuts and shut-off valves
- Needle-nose pliers and standard slip-joint pliers
- 5.5 meter tape measure with a locking tab
- Utility knife with a snap-off blade
- Small level, around 24 cm, for shelves and picture rails
- Stud finder, since Japanese apartment walls hide studs at irregular spacing
I keep a second, smaller version of this same kit in my car. In the first two years I lost close to 3 hours a month driving home for a forgotten tool before I doubled up.
Two Power Tools Worth Buying Early
You don’t need a full workshop, but two power tools pay for themselves fast. A cordless drill driver, 18V class, handles everything from tightening loose cabinet hinges to installing curtain rails and assembling flat-pack furniture between tenants. Mine has run for six years on its original two batteries and has driven what I’d estimate is well over 10,000 screws. The second is a compact oscillating multi-tool, useful for trimming door bottoms that stick after a tatami-to-flooring conversion, cutting caulk lines cleanly, and sanding small patches. Together these two tools cost me about 22,000 yen when I bought them, and I’ve never regretted the purchase.
Plumbing and Electrical Basics

Tool Storage & Workshop Organizer
A well-organized toolbox saves 20 minutes on every job. Multiply that by 100 repairs.
Plumbing calls are the most common emergency you’ll get, so stock a plunger, a roll of plumbers tape, a basin wrench for tight under-sink nuts, and a set of replacement washers and O-rings sized to your fixtures. A cheap 20,000 yen wet-dry shop vacuum has saved me from three separate flooded-bathroom situations, and it pays for itself the first time you use it. On the electrical side, keep a non-contact voltage tester, a small assortment of wire nuts, and a headlamp, since half of the electrical issues I’ve dealt with happened in a dark closet or crawl space where a phone flashlight just isn’t enough. I never do work beyond swapping a light fixture or outlet cover myself; anything touching the breaker panel goes to a licensed electrician, and that boundary has kept me safe for over a decade. Knowing where every unit’s main breaker and water shut-off valve is located has probably saved me more money than any single tool in this list, since a fast shut-off can turn a flood into a minor mop-up job instead of a full floor replacement.
Consumables and Small Parts Add Up Fast
The tools get the attention, but consumables are what actually get jobs finished. Keep a small parts organizer stocked with drywall anchors, assorted screws and nails, caulk in white and clear, spackling compound, and a few spare toilet flappers, since that single part explains a surprising share of running-toilet calls. I restock this box about once every 3 months across my properties, spending roughly 4,000 yen each time, and it means almost every repair gets finished in one visit instead of two.
Keep It Organized or It’s Useless
None of this matters if you can’t find the right tool in under a minute while a tenant is standing there. I use a single hard-sided case for hand tools, a separate bag for the power tools and batteries, and a labeled bin for consumables, all stored on one shelf near the door so I can grab everything in about 30 seconds on my way out. When I ran a loose pile of tools in a cardboard box for my first two properties, jobs that should have taken 20 minutes regularly stretched past an hour just from searching. Organization isn’t a luxury step, it’s the difference between a quick fix and a wasted evening. I also keep a laminated checklist taped inside the case lid listing what should be in there, so after a big job I can restock in 2 minutes instead of discovering a missing wrench on the next emergency call.
Start small, buy quality where it counts, and add specialty tools only when a specific job demands them. That’s the approach I use across all 9 of my properties, and it’s kept my repair costs and my stress level lower than I ever expected when I started.
