This is exactly the kind of tired, everyday decision where "just grab a taxi" quietly costs you ¥6,000. Mio doesn't care that it's late — here's the math.
A late-night taxi starts around ¥500 base and climbs ¥300–500 per km, plus a ~20% night surcharge — so a real ride home is often ¥3,000–8,000+ depending on distance (illustrative). A capsule hotel is ¥3,000–5,000 for a bed, shower, and lockers. A manga/net café night pack (roughly 8 hours) is ¥1,500–2,500 and usually includes a reclining seat or flat booth, free soft drinks, and often a shower. Waiting for the first train (~05:00) costs nothing but the night.
| Distance home | Est. late-night taxi | Mio's pick |
|---|---|---|
| Under ~3 km | ¥1,500–2,500 | Taxi — cheap and you sleep in your own bed |
| ~3–6 km | ¥2,500–4,500 | Coin toss — taxi if you value sleep, net café if you value ¥ |
| ~6–12 km | ¥4,000–7,000 | Net café or capsule — cheaper than the fare |
| Over ~12 km | ¥7,000–12,000+ | Capsule/net café, then first train — don't pay ¥10,000 to sleep in a moving car |
So the honest answer is "how far are you?" Close in, the taxi is genuinely the smart buy. Far out, a ¥2,000 net café plus a ¥400 first-train ticket beats a ¥7,000 taxi by a wide margin — and you get a shower out of it.
The daytime fare you remember isn't the fare you'll pay. From roughly 22:00 to 05:00, taxis apply a ~20% late-night surcharge, and traffic-free empty roads don't help because the meter also ticks on time when idling. A route that's ¥4,000 at noon can be ¥4,800+ at 1 a.m. — the exact moment your judgment is worst.
Smart middle path: if you're more than a few km out, walk to the nearest net café (they're everywhere near big stations), take the shower, sleep in the booth, and catch the first train. Total: ¥2,000 all-in vs a ¥6,000 taxi.
Under ~3 km → taxi. ~6 km or more → net café or capsule, then first train. And if you're doing this most weekends, the real fix isn't a cheaper option — it's leaving 30 minutes earlier. The cheapest last-train problem is the one you never have.
