Common problems & how founders solve them
The friction points Japan builders keep hitting.
Local payment rails aren't obvious
Choosing between global Stripe and local providers matters Stripe JP + KOMOJU. Convenience-store payments (Konbini) still matter.

We see it constantly: 6-month roadmaps, no launch. The 3-project cap is designed against exactly this failure mode.

Translation & tax questions block launch
