New Tesla Supercharger Opens in Ota-ku, Japan — 4 Stalls Now Live in Kamiikedai

Tesla's Japan charging network just got a little denser. The official @TeslaCharging account confirmed the opening of a brand-new Supercharger station in Kamiikedai, Ota-ku, Tokyo — a 4-stall site that brings fast DC charging to one of the capital's busiest southern wards.

📊 Station at a Glance

Ota-ku sits in the southern part of Tokyo, bordering Kanagawa Prefecture. It's home to Haneda Airport and a dense residential population — making reliable EV charging infrastructure here genuinely useful, not just a checkbox expansion. The Kamiikedai neighborhood specifically is a quiet residential district, and a local Supercharger means owners in the area no longer need to route through central Tokyo or head toward Yokohama for a fast charge.

🗾 Japan Network Context: Where This Fits

This opening is one piece of a much larger push. According to verified data, Tesla operated approximately 695 Supercharging stalls across 138 locations in Japan as of December 2025. The company has set a target of reaching over 1,000 stalls at 180–200 locations by 2027 — a roughly 40% increase in stall count within two years.

The pace of expansion is picking up to match demand. Tesla's EV sales in Japan doubled between 2022 and 2025, with the company surpassing 10,000 units sold in Japan for the first time in 2025. More cars on the road means more pressure on the charging network — and Tesla is clearly responding.

On the technology side, Tesla introduced its first V4 Supercharger stalls in Japan at Enshu Morimachi, Shizuoka Prefecture, when it celebrated its 600th Japan Supercharger milestone in October 2024. V4 hardware supports cabinet output up to 500 kW and is expected to become standard at new sites throughout 2026. Tesla has not confirmed whether the Kamiikedai station uses V3 or V4 hardware — owners should check the Tesla app for stall-level power ratings once the station appears in navigation.

🚦 Owner's Action Plan

1. Update your Tesla navigation: New Supercharger stations typically appear in the Tesla navigation system within days of opening. If Kamiikedai doesn't show yet, a soft reboot (hold both scroll wheels) can refresh the map data.
2. Add it to your route planning: If you regularly travel between central Tokyo and Kanagawa, Kamiikedai is worth adding as a waypoint option. It sits in a residential area, which typically means lower congestion than airport-adjacent or highway stations.
3. Check stall availability in the app: Open the Tesla app → Charging → find the Kamiikedai station to see real-time stall availability and power output before you head over.
4. Non-Tesla EV owners: If you drive a vehicle with a NACS (SAE J3400) port — including select Sony Honda Mobility Afeela models or future Mazda and Stellantis vehicles — this station may be accessible to you depending on your vehicle's software and Tesla's network access policy in Japan.

📰 Deep Dive

The Kamiikedai opening is a small but telling data point in Tesla's Japan infrastructure story. Ota-ku is the kind of location that signals Tesla is moving beyond the obvious highway corridor and tourist-area placements and starting to build genuine urban density. For owners who live or work in southern Tokyo, a neighborhood Supercharger is a fundamentally different use case than a highway fast-stop — it enables top-up charging during errands or a dinner, not just long-distance travel.

The broader 1,000-stall-by-2027 target is ambitious but credible given the pace of recent openings. Japan's charging infrastructure has historically lagged behind the country's EV adoption ambitions, and Tesla's willingness to invest in dense urban placements — rather than waiting for government-led charging corridors — gives its owners a real day-to-day advantage. The doubling of Tesla sales in Japan through 2025 suggests that charging confidence is translating directly into purchase decisions.

One thing worth watching: the NACS adoption wave in Japan. With Mazda committing to the standard from 2027, Stellantis following suit, and third-party hardware suppliers like ABB and PowerX planning NACS-compatible equipment in 2026, Tesla's Supercharger network in Japan is on a path to becoming a shared public resource — not just a Tesla-exclusive perk. Each new station opened today is infrastructure that will serve a much wider pool of EV drivers within the next two to three years.
