Put today's walkable window on your own site

One line of HTML. No account, no cost, no tracking of your visitors. Built for Hiroshima hotels, ryokan, tour operators and anyone writing about Miyajima.

What it looks like

The code

<div id="miyajima-tide"></div>
<script src="https://miyajimatides.com/embed/widget.js" async></script>
<p><a href="https://miyajimatides.com/">Tide data by Miyajima Tides</a></p>

Paste it where you want the box to appear. The script draws into the empty div; nothing else on your page is touched. It brings no jQuery, sets no cookies, and makes no further requests.

The one condition

Keep the visible link back to miyajimatides.com. That is the whole price. The tide calculation is free to use, and the link is what pays for keeping it free.

Raw data instead

If you would rather build your own display, the same figures are published as JSON:

https://miyajimatides.com/api/today.json

CORS is open, so you can read it from the browser. Same condition: show the link.

Where the numbers come from

• Japan Meteorological Agency tide predictions for Hiroshima (station Q8, Ujina).
• Walkable below 100 cm; the gate floats above 250 cm. These are practical thresholds, not official ones.
• The reference station is Hiroshima, about 15 km from Miyajima in the same bay. Predictions are astronomical: strong wind and low pressure move real water levels.
• Regenerated every day. If the widget ever finds itself showing a date that is not today, it stops making claims about “now” and points at the live page instead.
