Add comparison cities relevant to your schedule: Click + Add City and search for cities such as New York, London, and Sydney to compare Karatsu with major finance, media, and Asia-Pacific business hubs. These comparisons are practical for exporters, remote teams, and travel planners because Japan often overlaps only partially with Europe and has little same-day overlap with the US East Coast.
Drag across the grid to select a workable meeting window: Use the Select button if needed, then drag on Karatsu’s 24-hour timeline to highlight a range such as 9:00 AM to 11:00 AM JST. On a standard-time comparison, that shows as 8:00 PM to 10:00 PM the previous day in New York, 12:00 AM to 2:00 AM in London during UK winter, and 11:00 AM to 1:00 PM in Sydney, which quickly confirms whether a morning meeting in Karatsu works better for Australia than for North America or Europe.
Move, resize, and export the selected time range: Drag the purple selection by its center to test alternate slots, or use the left and right handles to tighten the window before sharing it. Once selected, use ICS download, Google Calendar, Gmail, Copy to clipboard, or Share link so a distributor, travel group, or remote project team sees the Karatsu meeting time correctly in their own local calendar.
About Karatsu Time Zone
Karatsu uses the Asia/Tokyo IANA time zone, the standard time zone used across all of Japan. Its offset is UTC+9:00, also known as Japan Standard Time (JST), and this offset remains constant throughout the year. If it is 12:00 PM in Karatsu, it is 3:00 AM UTC on the same day.
Karatsu does not observe daylight saving time, and Japan currently does not shift clocks in spring or autumn. That means the local time in Karatsu stays stable year-round, which simplifies scheduling for factories, shipping operations, tourism businesses, and international teams that need predictable meeting times with Japan. While countries such as the United States and United Kingdom change offsets seasonally, Karatsu remains fixed at UTC+9.
Karatsu is located in Saga Prefecture on the island of Kyushu in western Japan, but it shares the same national time standard as Tokyo, Osaka, Fukuoka, and Sapporo. Nearby countries and regions operate on different offsets: South Korea is also UTC+9, China is UTC+8, and Taiwan is UTC+8, so Karatsu is 1 hour ahead of Shanghai and Taipei but aligned with Seoul. This matters for ferry travel, regional trade, and cross-border business coordination in East Asia.

Does Karatsu observe daylight saving time?
No, Karatsu does not observe daylight saving time, and Japan does not currently change clocks seasonally. That means Karatsu stays on UTC+9 in January, July, and every month in between, which makes recurring international scheduling more predictable than in countries with spring and autumn clock changes.
What is the time difference between Karatsu and New York?

What is the best time to call Karatsu from the US?
For the US East Coast, the most practical window is usually Karatsu morning, roughly 8:00 AM to 10:00 AM JST, which falls in US evening the previous day. For the US West Coast, late morning or early afternoon in Karatsu can work better because the Pacific time zone is even further behind, so many teams schedule Japan calls near the end of the US workday or the start of Japan’s day.
What is the best time to call Karatsu from the UK?
The best time to call Karatsu from the UK is often late afternoon or early evening in Karatsu, which maps to UK morning or around midday, especially during British Summer Time. If you try to call Karatsu at 9:00 AM JST, it is only 12:00 AM in London in winter or 1:00 AM in summer, so that slot is usually too early for UK-based staff.
What is the UTC offset for Karatsu?
Karatsu uses a fixed UTC+9:00 offset all year. This means local time in Karatsu is always nine hours ahead of Coordinated Universal Time, with no daylight saving adjustment to account for in spring or autumn.
What currency does Karatsu use?
Karatsu uses the Japanese yen (JPY), the national currency of Japan. Visitors and business travelers will use JPY for accommodation, local transport, dining, and retail purchases, while international invoices and supplier payments to Japanese companies are also commonly settled in yen.
Is Karatsu the same time as Tokyo?
