Working remotely from Japan

Japan has world-class infrastructure and zero internet restrictions. The challenge is the time zone — 13–17 hours ahead of the US. Your IT will see the IP and the timezone metadata; what they don't see is up to you.

What your IT actually sees from Japan

• IP geolocation. Japanese consumer IPs (especially NTT FLET'S fiber) resolve to "Japan" with extremely high confidence. M365 + Google Workspace flag it on first login. Okta, Duo, and any conditional-access policy with country rules will trigger on the very first authentication attempt.
• MFA push location. A Japanese SIM (Docomo, au, SoftBank) or local WiFi gives the push approval the same Japan stamp. Two foreign signals, both Japan, on the same login event = obvious story.
• Working-hour mismatch. This is the biggest Japan-specific tell. Even if you handle the IP and timezone metadata, your activity timestamps in Slack/Jira/email will cluster at unusual US times. A pattern of "always responds at 11pm ET" over weeks is observable in any analytics dashboard your manager pulls. The cleanest cover: have a story for why you're working evening hours.

Working hours overlap

Japan is 13–17 hours ahead of the US. There's no clean overlap during normal business hours either way:

• Best case (Eastern): 9pm Japan = 8am ET. Your "morning standup" is your evening. Doable if you're a night-owl or live solo.
• West Coast: midnight Japan = 9am PT. Genuinely brutal — you're up until sunrise to make a meeting.
• Strategy: Most people who do Japan well front-load: do all real-time meetings in the evening Japan time (8pm-midnight), then async heads-down work the rest of the day.

Banking & streaming gotchas

Banking: Japanese ATMs only accept cards with international PIN routing — not all US debit cards work. Use 7-Eleven ATMs (Japan Post Bank network) — they're the most reliable. Cash culture is strong; carry more yen than you would dollars in most US cities.

Cards: US bank fraud algorithms generally treat Japan as "low-fraud" and won't auto-block. Set a travel notice anyway. Capital One, Schwab, and Charles are friction-free.

Streaming: Netflix swaps to JP library (a treasure trove of anime if you're into it; English UI stays). Hulu blocks. ESPN+ blocked. Apple TV+ works. Most others block. If your IP shows home, your US libraries stay intact.

Phone: US phones work on Japanese SIMs but are often locked. Mobal, Sakura Mobile, and IIJmio are good prepaid options — passport scan required.

The "Japan-specific" things most people miss

• Japanese fiber is the fastest in the world. 1 Gbps symmetric is standard. Latency to US East = ~150ms (mostly fixed by physics, not by ISP); to US West = ~80ms. Video calls work fine but feel slightly delayed.
• Co-working spaces require ID + introduction. Most spaces in Tokyo expect an introduction or membership. Drop-in spaces exist but are pricier than European equivalents. Most apartments have great fiber — work from there.
• Earthquake auto-alerts. Your phone will receive Japanese government emergency alerts — they're loud and unmissable. Not relevant for IT but worth knowing if you're on a Zoom call.
• Tatemae and IT. Japanese culture has strong norms around appearing professional. If your camera shows a tatami room or sliding doors during a call, plan to address it (virtual background, neutral wall) — these are obvious "you're in Japan" tells.
