Where to buy yakiami grill net in tokyo?

Im looking for yakiami grill net in Tokyo and will make a family trip next year. Anyone has ideas about where to get one? Thanks!

Disposable Yakiami can be found at 100 Yen shops.

Thanks man. But im sortof looking for "double-layer" one that could last longer rather than disposal ones.

Something like this?

You can purchase at Tokyu Hands in Shibuya, Ikebukuro or Shinjuku and major homeware stores around 700 - 1000 Yen.
Disposable net is 100 -200 Yen.

I am sure you can get them in Kappabashi Street (かっぱ橋道具街, Kappabashi Dōgugai)

If you are in Osaka, Sennichimae Doguyasuji Shopping Street is the place.
