When I first started managing properties in Tokyo, I made the classic mistake: I added amenities based on what I would want as a guest. A premium coffee machine. Some books. A decorative plant. Lovely in theory. In practice, guests rated the WiFi speed more than any of it.

After managing multiple properties and reading hundreds of guest reviews, I’ve built a much clearer picture of which amenities actually drive higher ratings, more bookings, and the ability to charge more — and which ones just look good on a listing page.

TL;DR

  • High-speed WiFi has the single largest impact on guest satisfaction of any amenity — treat it as infrastructure, not an extra
  • Japan has unique baseline expectations: slippers, a trash separation guide, and an easy-to-use shower are make-or-break for domestic guests
  • A few targeted additions (pocket WiFi to lend, quality towels, a simple welcome kit) can justify 10–15% higher ADR
  • Self-check-in hardware pays for itself quickly by reducing host workload while improving guest experience
  • Many “lifestyle” amenities that look great in photos generate essentially no measurable uplift in reviews or bookings

Why Do Amenities Matter Differently in Japan?

Japan’s accommodation market is competitive, and guests — both domestic and international — have high expectations. But the shape of those expectations differs from markets like Berlin or Bangkok.

Japanese domestic travelers, who make up a meaningful share of short-term rental guests even at internationally-focused properties, expect a level of thoughtfulness that many Western guests simply don’t notice. International guests, meanwhile, encounter Japan’s unique customs — garbage separation rules, the slippers-at-the-door norm, the absence of a Western-style toilet seat in older buildings — and their experience will be shaped almost entirely by how well you’ve prepared them.

The gap between a 4.7 and a 4.9 on Airbnb — which can determine whether the algorithm shows your listing or buries it — often comes down to exactly these small, Japan-specific details.

What Is the Non-Negotiable Baseline for a Japan Short-Term Rental?

Every property needs to clear a basic bar before any “premium” amenities matter. Missing any of these is a review killer:

Fast WiFi. Japan has excellent internet infrastructure, and guests know it. They expect 100Mbps+ and many will run a speed test in the first ten minutes. If you’re still on ADSL or relying on a mobile hotspot, no amount of nice bedding will compensate. Fiber connections are widely available — get one.

Climate control that works. Tokyo summers are brutal; winters in central Japan are genuinely cold. A functioning air conditioner and heater aren’t amenities — they’re utilities. If either is slow, loud, or operates via a cryptic remote control (common in older Japanese units), fix it or replace the remote with a bilingual instruction card.

A trash separation guide. This is uniquely Japan. Guests — especially first-time international visitors — find the local garbage rules confusing, and getting it wrong creates real friction. A clear, laminated guide in Japanese and English (and ideally Korean and Chinese given the dominant inbound markets) prevents mess, reduces stress, and gets mentioned positively in reviews more reliably than almost any other single item.

Slippers. Every Japanese domestic guest expects them. Most long-stay international guests come to appreciate them. This is a ¥1,000 purchase with outsized impact.

A shower that works properly. Obvious on paper, but older Tokyo properties frequently have weak water pressure or confusing bath/shower toggle controls. Guests mention this in reviews. Test it yourself if you haven’t recently.

Which Amenities Actually Justify a Higher Price?

Once your baseline is solid, these additions have measurably moved our numbers:

Pocket WiFi to lend. Counterintuitive given how good the in-property WiFi is — but guests love having something to take out with them. It removes the real anxiety of navigating a new city without data, and guests mention it by name in reviews. If you’re already on a data plan, the per-unit cost is low.

Quality bedding and towels. Not “expensive,” but clearly not discount-bin. Hotel-weight towels are felt immediately. Guests don’t consciously think “these towels justify a higher rate,” but they do consciously write “the place felt very well looked after” — which amounts to the same thing.

A simple welcome kit. Tea, coffee pods, a few locally-bought snacks, a handwritten or printed welcome note. Cost per booking: ¥500–800. Review impact: disproportionately high. Guests who feel welcomed write warmer reviews, full stop.

A portable fan for summer. Air conditioning handles the bulk of cooling, but a small desk or bedside fan is often what guests want for sleeping. A ¥2,000 item that generates genuine appreciation in July and August.

A transit IC card (Suica/PASMO) with a small balance. A higher-commitment option, but for properties that attract airport-fresh arrivals or first-time Japan visitors, lending a pre-loaded card removes a real first-day friction point. Guests remember this.

What Are the Amenities That Look Good But Don’t Move the Needle?

Honestly, a lot of the lifestyle items that look great in photos.

A premium espresso machine photographs well and costs ¥15,000–30,000, but unless your guest profile is heavily coffee-focused, most guests won’t use it or won’t distinguish it from a basic drip machine. Good quality instant coffee serves 90%+ of guests just as well.

Board games, books, and printed local guidebooks in a binder — these rarely get used. A QR code linking to a curated Google Maps list of nearby spots is more practical, more current, and takes zero shelf space.

Decorative objects, artwork, and plants are valuable for listing photography but generate essentially no review mentions from actual guests.

How We Approach This at BenStay

Our method is to start from reviews and work backwards. We track what guests specifically mention — both positives and pain points — across properties, and we invest based on that signal rather than assumptions.

The consistent pattern: WiFi, cleanliness (the operations side), ease of check-in, and the garbage/slippers/temperature trifecta dominate guest comments. Everything else is secondary.

When we do add amenities, it’s matched to the guest profile of that specific property. Properties attracting longer-stay guests or remote workers get a better desk setup and an external monitor. Properties near transit hubs get the pocket WiFi and IC card. Properties with a strong domestic Japanese guest mix get more careful attention to the bathroom and kitchen.

On the maintenance and upgrade side, when we’re deciding whether to invest in better shower fittings or replace aging air conditioning units, being able to quickly compare contractor quotes through Aimitsu makes the ROI calculation a lot cleaner — especially when you’re weighing multiple properties at once.

FAQ

Q: Do I need to provide a washing machine in a Japan short-term rental?

For stays over three nights, a washing machine is close to expected — particularly by domestic Japanese guests. For shorter-stay properties it’s a strong differentiator rather than a hard requirement. If your property doesn’t have one, disclose this clearly before booking and note the nearest coin laundry in your welcome guide.

Q: What languages should my amenity guides and welcome materials be in?

At minimum: English and Japanese. Given that Korean and Chinese travelers consistently rank as the top inbound markets by JNTO arrivals data, adding Korean and Simplified Chinese to key guides — especially the trash separation guide — is worth the one-time translation effort.

Q: How often should I audit and refresh my amenities?

At minimum twice a year: before summer peak season and before the winter period. A practical ongoing cadence is every 15–20 guest stays — check condition, replace worn items, and scan your most recent batch of reviews for any recurring mentions. The reviews tell you exactly where to spend next.
