Tl;dr: Do you already love japanese flavors/snacks? Redbean, matcha, and sakura your go-to everyday flavors? Does the added shipping not bother you? This box is for you!
I tried three boxes and all of them were OKAY. Each box had at least one thing I really loved and one thing I had to spit out. Most items are good, with a decent variety.
For the Sakura and Mochi box the fish wafer came broken, as did my friend who was also getting the box (super disappointing since it was a really odd and new sort of item to try).
The three boxes I got had a sort of same-y issue, where there were starting be some staple items and flavors like monokas (the wafers taste gross and the filling can be good or bad. The sweet soysauce one was disgusting, some of them the wafers fall to pieces and others can be (enjoyably) eaten like an oreo)
Three boxes in a row really pushed sakura as a flavor (to which I can say typically tasted like literally nothing but smelled nice) As well as red bean paste. Let me tell you, I don't hate red bean paste. It's. . .fine, in moderation. But I can't eat it by the spoonful and there was so much of it in these boxes. I know it's a Japanese dessert staple but I would have liked some more variation on flavor. Everything fish flavored was not my cup of tea, though. Fortunately only the first box seemed to push it.
Now for the best part of these boxes. The creme de la creme, the top of the top; it's kinako. It basically tastes like unsweet peanut butter and these boxes encouraged me to purchase an entire bag of the stuff. I can now have kinako for everything. Put it on ice cream. Put it on mochi. Consume it sprinkled on PB&J, put it into your chocolate chip cookie batter. Go ham, the stuff is amazing.
Now price. The price is fine. . .before shipping. Once you include shipping the price becomes a little steep. Almost 50$ per a box (in my case) with about 30$-40$ worth of product inside. So yeah, not great, but not awful.
Lets talk about non food. The plate was super cute, and I use it as a nice trinket dish. The cup was equally cute, matched the plate and is not good for hot liquids at all. I burned my hands trying to drink tea out of this cup, and it sweated bullets when I put juice and some ice in it later. Still adorable. Then there's the bowl. The bowl is plastic, and small. It's a decent ice cream bowl or rice bowl. It's also apparently edible and contains wheat, milk, soy, and egg allergens according to the booklet. I haven't attempted to consume my bowl. Someone please tell me if the plastic bowl is tasty.
Tea. Box 1: Salt water. Box 2: Soup broth. Box 3: Normal?? I haven't tried the third tea yet, I'm almost afraid. The first two boxes seemed to prioritize pretty tea over drinkable tea. The soup broth one was fine, but I wish someone would have warned me.
Misc grievances: The booklet didn't tell me the rice paper was edible in box 2. Would have been nice to know, the mochi was delicious but I didn't realize the rice paper it was stuck to could be eaten.
Overall: The experience was fun, I enjoyed it. Sure there's a lot of complaining here but at the end of the day only one or two items went uneaten from most of the three boxes I got. 50$ is just a bit too much for me (After shipping) though, especially if some boxes will have a third or more of the content be a miss. I don't like monokas, or fish flavored things, and I prefer my red bean paste in moderation which at the end of the day means I'd personally rather save my money. I do think this box is for some people though, and those people will adore it. Overall I'll continue following what comes out of these boxes to (hopefully) see a larger variety of flavor as the seasons change and likely only subscribe here or there for one time purchases.
