Where to rent haneto costumes in Aomori

We are planning to go to the Nebuta Matsuri on August this year, and would like to rent a haneto costume to participate in the parade.

Does anybody know of a particular shop where we can rent them? It would be better if they could help us dress. I've read somewhere than not every shop does.

I would also like to know until what time the shops are usually open to return the costumes, because we were planning to take a train to Sendai early in the morning on the next day. Depending on whether we can return the costumes on the same date or not, we may need to change our plans.

Thank you very much for your help.

I believe your hotel can help you arrange this. Some seemed to have in-house rentals while others work with local rental shop I think. Try contacting them.

This is information of last year's Japanese.

There are several shops, somewhat, also it different price.
Please look at the shop rental(レンタル）.
Shop listed in the top (koubeya、神戸屋) seems to accept the contact in E-mail.
Maybe even at your hotel, you will get to correspond.
