Seeking Recommendations for Second Japan Trip (March 13-28)

Hello fellow travelers,

I'm planning my second trip to Japan from March 13th to 28th. Here's my current itinerary:

• March 13: Flight from Delhi to Tokyo
• March 14: Arrive in Tokyo at 6:30 AM; spend the day in Tokyo
• March 15: Flight to Okinawa at 11:45 AM, arriving at 2:45 PM
• March 15-18 (4 days): Exploring Okinawa
• March 19: Flight back to Tokyo at 12:40 PM, arriving at 2:55 PM
• March 20-27 (8 days): [Open to suggestions]
• March 28: Flight back to Delhi at 11:45 AM

I've previously visited Tokyo, Kyoto, and Nara. I understand I might be a bit early for the main cherry blossom season, but I'd love to catch any early blooms if possible. I'm open to day trips from Tokyo and wouldn't mind going for an easy hike.

Is visiting Mount Fuji feasible during this time? Are there other places around Tokyo where I can see cherry blossoms during my dates?

Thanks in advance for your suggestions!
