The Japanese version is only region locked in the sense of not being able to change the language & region nor being able to sign in using a foreign Nintendo account (it has to be a JP one). Cartridges from abroad (US, UK) do work but will automatically translate the UI into Japanese (if its supported).










I have a JP Nintendo account and payment method (on the eShop you can use gift cards & only reads JP CC). You use forwarders to acquire it at your own expense (shipping and customs value).
