Hour-by-Hour Comparison
Time Difference: Singapore to Tokyo
This page shows the live time conversion between Singapore and Tokyo. The hour-by-hour chart above makes it easy to find overlapping business hours for meetings or calls. Green highlights indicate standard business hours (9 AM – 5 PM) in each city.
The Easy Asia Pair
Singapore (UTC+8) and Tokyo (UTC+9) are just 1 hour apart — Tokyo is always 1 hour ahead. Neither city observes DST, so this gap is constant year-round. A 9 AM meeting in Singapore is 10 AM in Tokyo. This near-alignment has facilitated deep economic integration between Southeast and Northeast Asia.
Financial Coordination
The SGX (Singapore) and TSE (Tokyo) trading hours overlap significantly. SGX opens at 9 AM SGT (10 AM JST) and both exchanges are active simultaneously through most of the trading day. This overlap enables real-time cross-market arbitrage and portfolio management. Fund managers in Singapore can actively trade Japanese markets during normal business hours and vice versa.
ASEAN-Japan Business
Japan is one of ASEAN's largest trading partners and investors. The 1-hour gap between Singapore (ASEAN's financial hub) and Tokyo supports the tight supply chain integration between Japanese manufacturers and Southeast Asian production facilities. Toyota, Sony, and other Japanese multinationals coordinate their regional operations from the Singapore-Tokyo corridor with virtually no time zone friction.
Scheduling Tips
With only 1 hour of difference, Singapore-Tokyo scheduling is almost domestic in its simplicity. A 10 AM conference call works as 10 AM SGT / 11 AM JST — both perfectly within business hours. The only consideration: Japan's business culture values punctuality more strictly. Be precise with start times, even though the conversion is trivial. The 1-hour gap also means business travel between the cities (7-hour flight) involves minimal jet lag adjustment.
