Family-Friendly Month in Japan

I'm planning a one-month holiday in Japan with two adults and a toddler. We're looking for a close destination from Kuwait, preferably with easy access to family-friendly attractions. Key Requirements: - The primary focus of the trip will be visits to theme parks. - The destination should be within the city limits. - The trip should be designed to suit the needs of a toddler, with convenient accommodations and travel options. Ideal Skills and Experience: - Expertise in family travel planning, particularly with toddlers. - In-depth understanding of Japan's theme parks and family-friendly attractions. - Ability to provide detailed, practical travel itineraries.
