We started around 6 am and reached 5th station at 8:45 am. That was the most boring part of the trip. It is a zig-zag way, all rocky, decent slope and the sunny weather. You just keep turning every now and then. We almost kept running through that part. We got freshed at 5th station and I caught bus for Kawaguchiko at 9:30. Trek to Mt. Fuji was definitely tiring. I would advice to carry as much less weight as possible with you. You can buy drinks and supplements at intermediate stations, though they are costly but it will reduce the weight. Be well prepared for cold at the summit. At sometimes winds also flow heavily, so bring ear plugs/caps. Also, carry a walking stick, helps to reduce strain on knees. At 5th station some wooden sticks are available on sale and on intermediate stations, you can collect stamps on those sticks and bring them home as souvenirs. While climbing down, it's better to use some mask and eye protection. Also, make sure you have ankle length shoes. otherwise, just like me, you will need to keep taking out stones/sand at regular intervals from shoes or you can use duct tape to seal of the shoes entrance. There is no any scenery to enjoy during climbing. The only good thing about trek is the Sunrise and feeling of reaching to such a height ( 3770 meter). Otherwise there is nothing else than stone, rocks, sand and soil.
I reached Kawaguchiko around 10:30. It's a small town, with tourism as main occupation. You can see ads by different agencies, lots of hotels, restaurants etc. My hostel - K's hostel Mt.Fuji - was 15-20 mins walking from station. I reached there by 11 o'clock and checking time was 3 o'clock. They were kind enough to let me check in at that time and rest in lounge. But I couldn't get room as cleaning was going on. She showed me a nearby Onsen on map and I thought of relaxing there for sometime. Onsens are the hot springs all over Japan, some are artificial but mostly are natural. It is said that taking a dip in onsen for sometime heals all the body pains. I hadn't have the experience so far. So I thought what could be better day to test it than today. If it really helps, will cure my body pains from trekking and if doesn't, it will prove that it doesn't work. So, I went to onsen. I spent around an hour in it and it really cured my tiredness and body pain. I returned to hostel, but rooms were not yet ready. I took rest in lounge till 15:00 and then shifted to room. I slept for around 5 hours but that was a very sound and peaceful. I woke up around 8 o'clock. Looked for any Indian restaurant nearby. There was one, 10 mins walking. I went there, ate up to full bream, returned to hostel and slept again.
