Not sure if it's a good film or not all in all, but 'Escapade in Japan' is rather wholesome so I enjoyed it.
Can kid actors Jon Provost and Roger Nakagawa act? Not to be harsh, but no. However, that honestly doesn't even matter as they're extremely likeable and pretty adorable together across the film's plot. On the latter, it's a thin and far-fetched story, yet it works to create a cute adventure.
Cameron Mitchell and Teresa Wright are alright elsewhere on the cast, while Clint Eastwood makes his last fully uncredited role with a minor showing. The film missteps one or two times, but overall it's proper sweet. It also shows, from what I could tell anyway, Japanese culture off well, which wasn't always going to be case for a release from this era.
If you were to be critical it probably isn't all that, but it's charming and I'd undoubtedly watch it again. Deserves more eyes on it.
