Why Japanese Era Converter on sakutto is safe
Many online tools upload your files to external servers for processing. This tool never sends your input data to any server β everything is processed entirely in your browser.
* Some AI-powered tools require server-side processing. Tools that send data to a server will always notify you beforehand.
| Comparison | Typical online tools | sakutto |
|---|---|---|
| Where data is sent | Uploaded to external servers | Nowhere β processed in your browser |
| Data leak risk | Risk during transfer and server storage | No risk β no network transfer occurs |
| External traffic | File data travels over the internet | No file data appears in network logs |
| Offline use | Not possible (server required) | Works offline after initial load |
How browser-based processing works
- WebAssembly (WASM): Processes input data in your browser at near-native speed. No server communication occurs.
- Web Workers: Runs on a background thread separate from the main thread, so your browser stays responsive during processing.
- After processing, your browser automatically frees the data from memory. No input data remains outside your device.
For IT security teams: How to verify
You can verify that sakutto never sends your input data externally by checking the Network tab in your browser's DevTools while using the tool. You'll see that no requests involving your input data are made. This can also serve as documentation for your IT security team.
Frequently Asked Questions
Which Japanese eras are supported?
This tool supports the five modern Japanese eras: Meiji (from 1868), Taisho (from 1912), Showa (from 1926), Heisei (from 1989), and Reiwa (from 2019). These eras are part of Japan's traditional calendar system used alongside the Western (Gregorian) calendar.
How are transition years displayed?
For years when an era change occurred, both eras are shown. For example, 2019 displays as both "Heisei 31 (until April 30)" and "Reiwa 1 (from May 1)."
Are the conversion results accurate?
Yes. The start and end dates for each era are based on official government records. Note that for the early Meiji period (before 1873), the traditional Japanese calendar was in use, so dates are displayed in the Gregorian calendar equivalent.
Is my data sent to a server?
No. All conversion happens entirely in your browser, and no data is ever transmitted externally.
What year range is supported?
The tool supports conversions from 1868 (Meiji 1) through 2100.
