What's the best eSIM in Japan for a business trip?

Hi, I know this isn’t really the topic of this forum, but I wasn’t sure where else to ask, and there are people here who travel for trade shows or overseas orders, so I’m giving it a shot. I’m heading to Japan in three weeks to scout out suppliers for consumables (inks, transfer paper, that sort of thing), and I’m having a hard time finding decent internet connectivity there. I’ve seen that eSIMs have become the go-to solution to avoid getting ripped off by your usual carrier, but there are so many conflicting reviews online that I can’t make heads or tails of it anymore. So my question is simple: what’s the best eSIM Japan for about ten days, with fairly heavy daily use (maps, emails, a few photos to send on the fly)? Airalo, Ubigi, Nomad, Holafly—I’ve looked into pretty much all of them, and honestly, the reviews are all over the place. If anyone has tried one recently, I’d love to hear about it.
