Reddit mentions of Celestial Seasonings Herbal Tea, Cinnamon Apple Spice, 20 Count (Pack of 6)

>chamomile, ginger, cinnamon, apple pieces and natural flavors

How about the Stash version, seems quite close: https://www.amazon.com/Stash-Tea-Chamomile-packaging-Individual/dp/B003D4IYQC?th=1

Alternatively, consider brewing the Egyptian chamomile and a ginger tea together. Apple/ginger is a nice taste:

1. Herbal Apple Ginger tea
   
2. Celestial Apple Ginger tea

2 suggestions - if you think herbal teas might be OK:

• Get that an assortment pack of Celestrial Seasons, probably the fruit sampler. It has some nice teas in it. I would probably give them 2 boxes. Some of the flavors are really nice.
  
• Pick a few boxes of Tazo Tea or Similar brands to give them. Pick some nice flavors you know taste good. Some of these might be a bit unusual for Japan, and might be appreciated.

  If it were me, I would also buy a box of some of these flavors from this sampler:
  
  Country Peach, Razzberry Zinger, Black Cherry (all really good). Lemon Zinger tea is also excellent.

It's good stuff. Hopefully this isn't breaking the rules, but here is a link. I bet you can find it in your local grocery store.
