Maxing Tsumitate vs Seichou NISA

Hi all

I’m 24 and new to investing with NISA. I’ve just opened my SBI account and would appreciate some general guidance.

Some general questions I have:

  1. I’m planning to contribute ¥100k/month(with card) to a Tsumitate NISA starting May, and I’ve already bought ~¥400k in a Growth NISA. However my colleagues who use Rakuten tell me I should try to max out my Tsumitate. But are there general advantages to maxing out Tsumitate? If iI buy ¥400k in a Growth NISA does it not make up for it? And does it make sense for someone early in their career to attempt maxxing out the full ¥3.6mil NISA limit if it's possible?
  2. How does timing usually work for NISA withdrawals? Is it typical to leave investments untouched for decades, or are there common situations where people cash out earlier?
  3. How do people generally approach timing contributions for Growth vs. Tsumitate NISA? Is there a difference between lump-sum vs. gradual investing? Is there such a thing as "waiting" for the ETF to drop based on the current geopolitical climate?
  4. Is it a good idea to only invest in eMAXIS Slim All Country? Is it the "safe" option?
  5. For someone with cash from previous investments in a U.S. brokerage account, are there general considerations for wiring it over to a Japanese bank account? If I wire the $ to my ¥ account, would it make sense to do so now since the yen is weak(I plan to live here atleast another 5 years)
