Be specific a bit. You want to do Tokyo and Hiroshima only in 2 weeks? Or Tokyo and all surrounding areas, then Kansai all areas, then Hiroshima area?

Can be done, but sked u can't really enjoy.
Ur 2nd option is pretty much safe and doable

I also traveling to Japan at 31 March till 10th April. ...any suggestions I need to take care?
Ps: I am newbie =_=

11 days at Osaka only was not too long.
If you want really betul betul cover full osaka.I can be tour guide.  It takes 90 days fully cover all.

No need JR pass.
It was useless in Kansai Area and Tokyo area. Plus shinkansen ride just one way.

If Shinkansen ride was 2 way then worth it.

If you dunno. Dont give false info to others.

Kansai Area are JR kill zone. JR are very limited usage in.
Hakone are totally  JR kill zone.
Tokyo also JR kill zone.

Kyoto to Tokyo one way just Rm530.

Why want spent Rm 1100 for JR rail pass? While usage just only 30%

wow, you're going the same time as i do haha.

Except my plan is as below:

31-Mar --> Arrive Tokyo 7am (discover around Asakusa, since we're staying there)
1-Apr --> Tokyo (Tsukuji, Tsukushima, Odaiba, Shibuya, Harajuku, Shinjuku, Ikebukuro)
2-Apr --> Tokyo (Akihabara entire day)
3-Apr --> Hakone
4-Apr --> Hakone + Kamakura
5-Apr --> Kamakura
6-Apr --> Back to Tokyo (still deciding where to go)
7-Apr --> Depart to Airport (unsure plans)

JR rail pass are biggest of all JR pass. It cover whole Japan.
JR west pass are useless if you no planning go Himeji , Okayama  , Hiroshima.

Kansai I already mention , it was JR kill zone. JR train are very limited used. Why still waste money on JR passes?

Kansai area are fully cover by  Subway , Nankai , Hankyu , Kintetsu. JR just a small actor.
Entire Kansai area only Universal Studio Japan are ezclusive JR line.  So you buy that stupid JR pass to ride to USJ only?

Lipoting in from tsukiji. As expected, RegentCid daikor tips of the month five thumbs up, super gooding. 👍👍👍👍👍

One change I noticed. Previously at inner market only the 'big two' sushi shop will long queue. Nowadays every single shop oso got a dozen ppl outside.

Depends on your definition of 'necessary.' A pocket wifi is most certainly not mandatory; you can get by with just spotty wifi hotspots and asking for directions from random strangers. But for me I always rent so I can whip up a quick google search or directions whenever things don't go exactly as planned.

Anyway reporting in from Sapporo/Otaru. Today the weather farked up our plans entirely. Rained the whole day + winds were the Destroyer of Umbrellas kind. Saw aunties and salarymen getting soaked after the winds turned their umbrellas inside out lol.

I have did some research and google so many website i found so confuse and don't really know where is a must visit place..especially kyoto.

i need people with experience to tell me their experience maybe they can guide me on planing my japan trip or maybe my plan is not good enough. you can help me to amend or update for me ok. its my first time to japan with gf.

thanks..

Cheaper but longer.
