1. Reference the right stock
Compare only against listings within ±5 minutes station walk, ±10㎡ size, ±10 years age. Suumo, Athome, Homes have comparable-listing filters that make this quick. Pull the median asking rent, not the average — outliers on both ends distort.
2. Advertise-and-move seasonality
- January–March: peak move-in season (jobs / university start April 1). Highest-price window; also highest AD budget from brokers.
- September: secondary peak (H2 transfers).
- Summer & December: slow. Cutting rent ¥2,000 in July is often faster than holding out.
3. AD (advertising fee)
“AD 1” means the landlord pays the broker 1 month of rent for finding the tenant. Standard is AD 1; slow properties advertise AD 2. Every AD point above 1 speeds fill by ~2 weeks in Tokyo. Calculate: 2-week rent lost vs 1 month AD — usually AD 2 is net positive when you're in month 2+ of vacancy.
4. Free rent (フリーレント)
Offering 1 month free at signing is more effective than cutting rent ¥1,000/month for the term. Sticker rent stays the reference for future comps. Brokers advertise “フリーレント1ヶ月” prominently.
5. The annual-take rule
Compare pricing scenarios on 24-month total take, not on monthly rent:
Scenario A — Ask ¥100,000, fills month 3 = 21 × ¥100,000 = ¥2,100,000 over 24 months Scenario B — Ask ¥97,000, fills month 1 = 23 × ¥97,000 = ¥2,231,000 over 24 months Winner: B by ¥131,000
6. Rent adjustment at renewal
Legally allowed only if you can show comparable rents have moved. Practically, tenants move if you push. Rule of thumb: don't raise rent unless comps are >5% above your rent — otherwise retention wins.
