Hi guys, I will landed in Narita, spend 2 nights in takayama and 4 nights in Tokyo. Is JR pass is the best options?

tokyo wide pass will be very useful if going several areas as it's valid for 3 days. can use for travel to Ichigo Yuzawa, Nikko and kawaguchiko + local travel around tokyo.

I can bet you no one here in this forum had better knowledge about Passes than me if you know who am I in this sector.   
I know all passes pro & cons.  That guy now focus on Kawaguchiko, so Fuji Hakone Pass are more suitable, unless he give me his full itinerary.

After 11 OCT all vaccine approved by WHO will be accepted and do not need PCR (Sino are on the approved list)

omg, big luggage is not allowed on shinkansen

JR Limited Express Fuji Excursion will go Kawaguchiko Station using Fujikyu line. Because JR & Fujikyu got agreement. But If you half way get down at Shimoyoshida Station, then from Shimoyoshida Station to Kawaguchiko Station, you need to buy ticket because JR Rail Pass are no longer valid.

There are only one JR Limited Express in entire Japan even using JR Rail Pass also need top up money for extra ticket was JR Limited Express Saphir Odoriko.
JR Rail Pass only covered until Ito Station. From Ito station to Izukyū-Shimoda station need top up another 3k Yen

This the only Train you cannot complete entire journey with using JR Rail Pass on JR Train. 

Bro, do you know how to get & exchange JR Rail Pass ?

Once you got the JR Rail Pass, you just need to show this ticket at counter, the station staff will open the special gate to let you pass.
If this JR Rail Pass, you no need buy any more train ticket from Machine. JR Rail Pass user using JR Shinkansen & JR Limited Express must get the Seat Reservation & Train Ticket at JR Ticket Office inside Train Station.

buggered, looks like pocket wifi it is then when travelling haha

Redeemed my krisflyer points for myself and my wife as our "honeymoon" trip for SQ.
Flying to Narita on 16 November until 30 November 2022 (Haneda all fully redeemed, sigh...)
I'm arriving 730am JPT 17 November in Narita, I have 13 days to go around.

Need sifus to help me on:
1. mySOS / Fast Track (for vaccination cert) and also Japan Web (for immigration/customs clearance), these need to be filled when? 1 week before travelling?
2. My wife wants to stay as long as possible in Tokyo to shop however I would want some detour out of Tokyo since we are having so many days in Tokyo.
- I'm thinking of going to see Mt Fuji, is a day trip enough? Thinking going to Hakone or Kawaguchiko just to see Mt Fuji and walkaround only, dont really have any other particular place. JR Tokyo Wide Pass is sufficient to cover?
- I'm thinking of going to Gundam Factory in Yokohama, probably another day trip.
- Wife wants to do strawberry picking but saw from internet, its not the right season. Unsure how to do this haha.
- Trying to formula a list what to do in Tokyo. She just gave a bunch of names like Shibuya, Ginza, Asakusa etc but unsure what to see there.
- We both been to Kyoto and Osaka before, so not too keen to go again.
