Regarding the "Manhole Cards" distributed by our museum, we have run out of stock and will temporarily suspend distribution as of Friday, January 30, 2026.

Distribution is scheduled to resume in mid-February 2026..
*The lot number for the next delivery will remain the same as the first issue.
*The reopening date is tentative and subject to change.

As soon as the date for resuming distribution is decided, we will announce it on our website and the Prefectural Sewerage Division website.

We appreciate your understanding and cooperation.
