Antique Orimoto

This is an antique orihon (folding book) from the Meiji or Taisho era.

It was stored together with the Edo period personal name register that I listed the other day.
The era might possibly be the late Edo period, but I cannot confirm it, so I have listed it as Meiji/Taisho.

Please understand that it is unclear whether the contents are writings of some waka poems or calligraphy practice.

The total length is estimated to be over 5 meters.
Please judge and confirm the contents and total length from the photos.

The condition is good with almost no tears or holes, but please understand that it is an old item.

Thank you for looking.
